1.1 Outline

The M65727 is a highly efficient motion estimation LSI used to estimate motion vectors for real-time encoding of dynamic images. M65727 can be used together with the frame memory, the M65721 (Controller LSI) and the M65722 (Pixel Processor LSI). It operates under the control of the M65721. M65727 accepts the template macro block (MB) data inputs from the M65721 and accepts the search window image data from the frame memory. It estimate the motion vectors by searching the minimum value of the mean absolute error between template block data and search window image data. It outputs the result to the M65721. The M65721 and the M65722 are able to generate prediction image using the above mentioned motion vector. The M65727 is designed so that it is applicable to MPEG2, the international video compression standard.

3. Outline of Functions

3.1 Outline

M65727 is configured as shown in Fig. 3.11. Its main components are the Input Unit, the Integer-pel Unit, the Motion detection Unit, the Half-pel / Dual-Prime Unit, and the Output Unit. When the Field/Frame mode is selected, the search window image data and template MB data are inputted to the Input Unit from their respective input ports. The data is used as the source data of the Integer-pel Unit after its order is changed. Then, the mean absolute error is calculated for each cycle at the Integer-pel Unit and the result is given to the Motion detection Unit and the best integer-pel precision motion vectors are estimated. Then, at the Half-pel Unit, the best half-pel precision motion vectors are estimated. The results are output from the Output Unit. When the Field/Frame Dual-Prime mode is selected, the template MB data and the search window image data of the first field and the second field are sent to the Input Unit from their respective input ports and become the source data of the Dual-Prime Unit. Then, the motion vector estimation is conducted at the Dual-Prime Unit and the results are output from the Output Unit. The functions of each unit are outlined below.

3.2 Block Configuration

3.2.1 Input Unit

The function of Input Unit is to output the search window image data and the template MB data to the Integer-pel Unit or Dual-Prime Unit with the necessary sequence and timing. Having this block enables the user to input comparatively freely the needed search window image data, using the sync signal (SSYNC) and the data enable signal (DENSWC), without regard to the motion estimation sequence. Similarly, necessary template MB data can be inputted fairly freely using the sync signal (MSYNC) and the data enable signal (DENMBC). The search window image data is inputted from the highest line towards the lowest line scanning left to right. The output sequence, on the other hand, starts from the leftmost column to the rightmost column and scans top to bottom. The input and output sequence of the search window image data for DualPrime are from the highest line to the lowest line and scanning from left to right. The search window image data is inputted as 4 vertical continuous pixels using the 32 bit input port. The Input Unit outputs a pixel per cycle by parallel-serial conversion.

3.2.2 Integer-pel Unit

The function of this block is to calculate the mean absolute error using the template MB data and the search window image data coming from the Input Unit. The Integer-pel Unit is composed of processing elements arranged in parallel, allowing high speed processing of the data to be evaluated. Three sets of calculated mean absolute error (corresponding to 16x16 block and two sets of 16x8 block) are given to the Motion detection Unit. Three sets of search window image data and the template MB data that correspond to the three sets of vectors are transferred from the integer-pel Unit to the Half-pel Unit.

DISTRIBUTION RESTRICTED. COPYRIGHT RESERVED 1995

3.2.3 Motion detection Unit

The function of this block is to select the vest motion vector of the integer-pel precision by comparing the 16-bit mean absolute error coming from the Integer-pel Unit. In addition, this block stores distortion of vector (0,0). In case when the distortions for multiple motion vectors are same, the most suitable motion vector is determined according to the order of priority. The output data depends on the modes. When the integer-pel precision search mode is specified during the Field/Frame mode, the following items are output to the Output Unit. They are three sets of best integer-pel precision motion vectors, the distortion for each, and the distortion for each vector (0,0). If the half-pel precision search mode is specified when the Field/Frame mode, the three sets of best integer-pel precision motion vectors and the distortion for each vector (0,0) are output to the Output Unit. And, the distortions for each integer-pel precision vector are output to Half-pel Unit.

3.2.4 Half-Pel / Dual-Prime Unit

This Unit calculates, during the Field/Frame mode, the mean absolute errors for half-pel precision vectors and detects the minimum distortions using the partial search window image data around best integer-pel precision vectors. The search window image consists of 18x18 pixels and two sets of 18x10 pixels around the three sets of integer-pel precision motion vectors detected at the Motion detection Unit. Eight kinds of interpolated images are generated by the half-pel interpolation filter. This image is matched against the template MB data given from the integer-pel Unit and the minimum distortions are detected from the above results. During the Field/Frame Dual-Prime mode, it detects the best dmv from the template MB data, the first search window image data and the second search window image data.

The first and second search window image consist of 18x18 pixel (10) each. The interpolated image from the first search window is generated according to the central position information (Displacement based on 0.5 pixel from 16x16 (8) pixels contained in 18x18 (10) pixels). Similarly, nine sets of interpolated images are generated through the interpolated filter from the second search window. Then, the nine sets of averaging images of the first and the second images are obtained. Next, the block matching between the template MB data is conducted and the best dmv is obtained. In case of the Frame Dual-Prime mode, not only the minimum evaluation value, but all the evaluated values for all the displacement are output.

3.2.5 Output Unit

This is the interface circuit related to the Output Port, DOUT. Necessary data comes from the Motion detection Unit and Half-pel / Dual-Prime Unit and is output to through DOUT in sync with the output request signal, OREQC.

3.3 Operational Modes

M65727 has the following operational modes which can be switched externally. This chapter outlines the operational modes of M65727.

3.3.1 Field / Frame / Field Dual-Prime / Frame Dual-Prime

M65727 is capable of 4 modes, namely Field mode / Frame mode / Field Dual-Prime mode / Frame Dual-Prime mode, to work with the prediction mode of MPEG2. These modes are specified as shown below using MODE pins. They must be specified before the chip operation and fixed during operation.

00: Field mode 01: Frame mode 10: Field Dual-Prime mode 11: Frame Dual-Prime mode

Field mode detects three sets of motion vectors simultaneously which work with 16x16 block, 16x8 (upper) block, and 16x8 (lower) block. Frame mode detects three sets of motion vectors simultaneously which work with 16x16 block, 16x8 (top) block, and 16x8 (bottom) block. Field Dual-Prime and Frame Dual-Prime mode detect the dmv.

3.3.2 The Search Range in Horizontal Direction

The search range in the horizontal direction can be selected from ±7.5 / ±15.5 / ±31.5 /± 63.5/ and ±127.5. The number of cycles needed for the motion vector estimation increases in proportion to the size of the horizontal search range. When ±15.5 or larger is specified as the horizontal search range, it is expected that multiple chips with interleaving manner are used. Refer to Chapter 5.5 for the number of chips needed when the horizontal search range is ±15.5 or more. The horizontal search range is specified as shown below using HSIZE pins. The horizontal search range must be specified before the chip goes into operation and should be fixed during the operation.

000: ±7.5, 001: ±15.5, 010: ±31.5, 011: ±63.5, 100: ±127.5, 101 ~ 111: Reserved

3.3.3 The Search Range in Vertical Direction

The vertical search range can be selected from ±7.5 and ±15.5. This range detects a minimum execution cycle (550 / 806) In the vertical expansion mode, the search range will be ±8.0 / ±16.0. See Chapter 5.5 for the number of chips needed for the vertical expansion. The vertical search range is specified as shown below using VSIZE pin. This must be done before the chip operation and it should be fixed during the operation.

0: ±7.5, 1: ±15.5

The vertical search range of ±7.5 can be used only under 27MHz operation.

DISTRIBUTION RESTRICTED. COPYRIGHT RESERVED 1995

3.3.4 Search range expansion for Vertical direction

The non-expansion mode of vertical search range is ±7.5 / ±15.5 as explained above. At this time, the order of priority for vectors, which have same distortions, gives the highest priority to the vector (0,0). When the search range expansion mode of the vertical direction is specified, the range becomes ±8.0 / 16.0. It becomes possible to expand the vertical search range using multiple chips. There are two modes for vertical expansion mode, upper-range of expansion and lower-range of expansion. The difference between the two is in the priority order for distortion equivalent vectors. If it is specified as upper-range, the vector (0, +8 / +16) will have the highest priority. If it is specified as lower-range, the vector (0, -8 / -16) will have the highest priority. See Ch. 5.2 for the order of priority for vectors. See Ch. 5.5 for the number of chips needed for the vertical search range expansion. This mode is specified by EXTND pin as shown below. This mode must be specified before the chip goes into operation and it should be fixed during the operation.

00: non-expansion, 01: reserved, 10: upper-range of expansion (Expansion), 11: lower-range of expansion (Expansion)

3.3.5 Half-Pel Precision/Integer-Pel Precision

The motion vector searched by M65727 is integer-pel precision during the integer-pel precision mode. In case of half-pel precision mode, half-pel precision vector is detected using interpolated search window image. The order of output data is shown in Table 2 (See Ch. 3.3.7). The above two modes have different outputs. This mode is specified by HLFPL pin as shown below. This mode should be specified before the chip operation and should stay fixed.

0: Integer-Pel Precision mode, 1: Half-Pel Precision mode

3.3.6 External Frame Memory Data Format

M65727 is capable of selecting the external frame memory (SW image) format only when the Frame mode is ON. This format is specified by the use of FMFMT pin as shown below. In other modes, only field format can be used. See Ch. 5.4 for details on formats. This mode must be specified prior to the chip operation and should be fixed during the operation.

0: Field format 1: Frame format

3.3.7 Operation Modes and Output Data

Data output from M65727 differs according to the operational modes. During the Field / Frame mode, three sets of data group, a group of 16x16 and two groups of 16x8, are output in sequence. Outputs from half-pel precision mode and integer precision search mode are different. When the Field mode is ON, a data group for 16x16 block is first output. A data group for 16x8 (upper) block is output next and a data group for 16x8 (lower) is output last. It takes 21 cycles. When the Frame mode is ON, a data group for 16x16 block is output first. A data group for 16x8 (top) is output next. And a 16x8 (bottom) block is output last. It takes 21 cycles. Table 2 shows a set of data outputs during the Field/Frame mode in the order they are output. In case of the Field Dual-Prime mode, Dual-Prime vector specifying code and its distortion are output in the order shown in Table 3. It takes 3 cycles to output data.

Operational modes

When the Frame Dual-Prime mode is used, the Dual-Prime vector specifying code, its distortion, and distortions for each displacement point are output in the order shown in Table 4. It takes 21 cycles to output data. The integer-pel precision motion vector outputs as motion vector corresponding to 16x16 block even for 16x8 block. Therefore, during the Frame Estimation Mode, the vertical component of the motion vector for the 16x8 block must be changed outside. When multiple chips are used to expand the vertical search range, the vertical components of the motion vectors must be changed for all blocks. Fig. 3.3.7-1 shows correspondence between 16x8 block and vectors.

3.3.8 Operational Modes and Dynamic Control Signals (for each processing cycle)

M65727 has controls which need to change every execution cycle. These controls differ according to operational modes as shown below. They are input to the chip through DCNT pins when DSYNC is asserted. One assertion is needed for each information write into the chip. Therefore, when a mode needs multiple control information, DSYNC must be asserted multiple times. DSYNC is asserted low.

*Valid / Invalid control of search range (Search Window Kill: SKILL)

This is used for Field/Frame/Field Dual-Prime/Frame Dual-Prime modes and shows whether they are valid or invalid with regard to the motion estimation range during the next execution cycle. When the horizontal search range is ±15.5 or more, it is necessary to give valid/invalid information for the search range multiple times within a 1MB processing time (1 processing cycle = 2,4,8 or 16 x (550/806 cycles)). The range of vector which is invalidated by the SKILL differs according to modes (Field, Frame, DualPrime, horizontal search range, etc.).

4. Operations

4.1 Reset Operation

When the RESET request signal (RESETC) is asserted to logical "L", M65727 goes into RESET cycle. This RESET cycle continues for two cycles after the RESET request signal is negated. It is a synchronized reset. It is sampled when the clock rises. It is prohibited to do activation for normal operation during the RESET cycle. When using M65727, it is necessary to execute this RESET operation before starting normal operation. The RESETC signal must be asserted over two cycles. In addition, there should be at least 10 cycle space before the ESYNC is asserted in order to start normal operation. Fig. 4.1-1 shows the RESET operation.

4.2 WAIT Operation

M65727 goes into WAIT cycle and stops the next cycle when the clock enable signal(CEC) is negated to logical "H". The values of registers in M65727 are held so that operations will be able to resume when the clock enable signal is asserted. The clock enable signal is sampled when the clock rises. Fig. 4.2-1 shows the WAIT operation.

4.3 Motion Detection Operation

In order to activate the motion estimation operation, which is a normal M65727 operation, it is necessary, during the Field/frame mode, to input the search window image data, template MB data, and the dynamic control input, in addition requesting the output and activating the execution cycle. In case of the Field/Frame Dual-Prime mode, it is necessary to input the search window image data, input template MB data, request output, activate processing cycle, and input dynamic control. Each operation will be explained below.

4.3.1 Search Window Image Input for Field/Frame mode

The data input to M65727 during Field/Frame mode are the search window image data and the template MB data. The search window image input can be performed in parallel with and independent of the motion estimation operation. The search window image input starts at the cycle proceeding the cycle where the sync signal SSYNC is asserted. When the vertical search range of ±7.5 is used, DENSWC must be asserted for 128 cycles during the data input. When the vertical search range of ±15.5 is used, DENSWC must be asserted for 192 cycles. The valid cycle refers to the cycle whose input data is specified as valid by the data enable specifying signal, DENSWC, of the search window port. Specifying this data enable allows no wait data transfer using the faster frame memory (SRAM). For lower cost implementation when DRAM is used as frame memory, wait states are useful to allow slower data transfer. Search window image is input in the order of raster scan starting from upper left of the screen. Four vertical adjacent pixels are input simultaneously using 32 bit DSWI. The data input must be completed within one execution cycle and at least 10 cycles or more space is needed between ESYNC and SSYNC. As long as this limitation is obeyed, the search window image input can be performed in parallel with the input of the template MB data and the actual arithmetic operation of the motion estimation.

Fig. 4.3.1-1 shows the input operation of the search window image.

4.3.2 Search Window Image Input for Dual-Prime mode

The search window image for Dual-Prime can be input in parallel and independent of motion estimation operation. The search window image input for Dual-Prime starts at the cycle proceeding the cycle in which the sync signal SSYNC is asserted. The M65727 uses 108 valid cycles for the first search window when the Field Dual-Prime mode is ON. After the first search window is complete the SSYNC is asserted to begin the input of the second search window. When the Frame Dual-Prime estimation Mode is used, there will be 72 valid cycles for the first search window, also 72 valid cycles for second search window. The valid cycle means the cycle whose input data is specified as valid by DENSWC. The search window image input data used for Dual-Prime is input in the order according to the raster scan starting from the upper left of the screen. Four vertical adjacent pixels are input simultaneously using 32 bit DSWI. The data input must be completed within one execution cycle and at least 10 cycles or more space is needed between ESYNC and SSYNC. As long as this limitation is obeyed, the search window image input for Dual-Prime can be run in parallel with the input of the template MB data and the actual operation of the motion estimation. Fig. 4.3.2-1 shows the search window image data input operation used for Dual-Prime.

4.3.3 Template MB Data Input

Inputting the template MB data can be performed independent of and in parallel with the motion estimation operation. Excluding Frame Dual-Prime mode, the template MB data of M65727 requires 256 pixels per 1 macro block. In case of Frame Dual-Prime Estimation Mode, template MB includes 128 pixels, but, 256 pixels (of which the last 128 pixels are dummy pixels) are needed. Inputting the template MB data starts at the cycle proceeding the cycle in which the sync signal MSYNC is asserted and continues for 256 valid cycles. The valid cycle refers to the cycle whose input data is specified as valid by the data enable specifying signal, DENMBC. It is possible, using this data enable specification, to do no wait data transfer using SRAM as frame memory. For lower cost implementation when DRAM is used as frame memory, wait states are useful to allow slower data transfer. The template MB data is input by scanning from the upper left-hand corner in vertical direction. The data input must be completed within one execution cycle and at least 10 cycles or more space is needed between ESYNC and MSYNC. As long as this limitation is obeyed, the template MB input can be run in parallel with the actual arithmetic operation of motion estimation and the search window image input. Fig. 4.3.3-1 shows the input operation of the template MB data.

4.3.4 Output Request

M65727 is capable of outputting the result of operation independently and in parallel with the arithmetic operation of the motion estimation. The output data is output by asserting OREQC, the output request signal. The output data becomes invalid when the RESET cycle occurs before during the motion estimation operation, or when ESYNC signal is asserted with the space less than the minimum number of execution cycle (550 / 806 cycles) before the output data becomes valid. Moreover, the space between ESYNC and OREQC must be at least 30 cycles. The output port uses tri-state output. This is activated by asserting OEC, the output enable signal. Fig. 4.3.4-1 shows the output operation.

4.3.5 Activation of Execution Cycle

The execution cycle of M65727 is activated by ESYNC, the execution sync signal. The minimum number of cycles for one execution cycle depends on the vertical search range. When the vertical search range is ±7.5, 550 is required. When it is ±15.5, 806 is required. It is necessary to assert ESYNC using an interval greater than the above minimum cycle. It is necessary to input the search window image data, the template MB data, and the dynamic control information within the execution cycle activated by one SYNC signal. It is not allowed to input the above across ESYNC's. Fig. 4.3.5-1 shows how the execution cycle is activated.

4.3.6 Dynamic Control Input

M65727 allows the control information to be input independent of and parallel to the arithmetic operation of the motion estimation. The dynamic control information is input by repeated assertion of DSYNC The control data input must be completed within one execution cycle and at least 10 cycles or more space is needed between ESYNC and DSYNC. As long as this limitation is obeyed, the dynamic control information can be input in parallel with the search window image data and the actual operation of the motion estimation operation. Fig. 4.3.6-1 shows the dynamic control input operation.

4.3.7 Number of Cycles Needed (from Data Input to Data Output)

The number of cycles needed depends on the operating modes. The minimum number of cycles needed for one execution cycle (from the assertion of one ESYNC to the assertion of next ESYNC) depends on the vertical search range. When the vertical search range is ±7.5, 550 cycles are needed; when it is ±15.5, 806 cycles are needed. When the Field/Frame Dual-Prime mode is used, the minimum cycles will be 550 cycles.

5.1 Macro Block Processing for Missing Search Range

M65727 conducts special processing when there is some missing search range in the macro block being processed or when a portion of the search range needs making invalid. M65727 requires to indicate, for each execution cycle, whether the range being searched is valid or invalid from outside. The information concerning whether the range being searched is valid or invalid (SKILL) is input to the chip from DCNT pin when DSYNC is asserted. However, the meaning of valid and invalid given by SKILL information differs according to modes.

*SKILL Information for Field/Field mode

In case when SKILL information indicates that the upper direction of the search range is invalid (Search Top), M65727 invalidate the following vectors.

[integer-pel precision vector]

The vector, whose vertical component is negative, is invalidated.

[half-pel precision vector]

When the vector, whose vertical component is zero, is selected as best integer-pel precision vector, the half-pel vector, whose vertical component is negative, is invalidated.

If SKILL information specifies that the down direction of the search range is invalid (Search

Bottom), M65727 invalidates the following vectors.

[integer-pel precision vector]

The vector, whose vertical component is positive, is invalidated.

[half-pel precision vector]

When the vector, whose vertical component is zero, is selected as best integer-pel precision

vector, the half-pel vector, whose vertical component is positive, is invalidated. If SKILL information specifies that both top and bottom directions of a search range are invalid at the same time, (Search Top and Bottom), M65727 invalidates the following vectors.

[integer-pel precision vector]

The vector, whose vertical component is positive or negative, is invalidated.

[half-pel precision vector]

The half-pel vector, whose vertical component is positive or negative, is invalidated. As a

result, the selected motion vector has a zero as a vertical component.

The vector, whose horizontal component is negative, is invalidated.

[half-pel precision vector]

When the vector, whose horizontal component is zero, is selected as best integer-pel precision

vector, the half-pel vector, whose horizontal component is negative, is invalidated. In case when SKILL information specifies the right direction among the search range is invalid (Search Right) when the horizontal search range is ±7.5, M65727 invalidates the following vectors.

[integer-pel precision vector]

The vector, whose horizontal component is positive, is invalidated.

[half-pel precision vector]

When the vector, whose horizontal component is zero, is selected as best integer-pel precision

vector, the half-pel vector, whose horizontal component is positive, is invalidated. Moreover, if both left and right directions among the search range are made invalid at the same time by SKILL information (Search Left and Right) when the horizontal search range is±7.5, M65727 invalidates the following vectors.

[integer-pel precision vector]

The vector, whose horizontal component is positive or negative, is invalidated.

[half-pel precision vector]

The half-pel vector, whose horizontal component is positive or negative, is invalidated. As a

result, the selected motion vector has a zero as a horizontal component. Therefore, if search top,

search down, search left, and search right are specified at the same time during the horizontal

search range is ±7.5, only (0, 0) vector can be selected.

When using ±15.5 or more as the horizontal search range, if SKILL information specifies that the left direction among the search range is invalid (Search Left), M65727 invalidates the following vectors.

[integer-pel precision vector]

No vector is invalidated.

[half-pel precision vector]

When the vector, whose horizontal position is most left in a search range of the current execution

cycle, is selected as the best integer-pel precision vector, the half-pel vector, whose horizontal

component is negative, is invalidated. When SKILL information specifies that the right direction among the search range is invalid(search right) using ±15.5 or more as the horizontal search range, M65727 invalidates the following vectors.

When the vector, whose horizontal position is most left in a search range of the current execution

cycle, is selected as the best integer-pel precision vector, the half-pel vector, whose horizontal

component is positive, is invalidated. When the horizontal search range is ±15.5 or more, it is prohibited to specify the search left and the search right at the same time except specifying all invalid (See below). When the horizontal search range is ±15.5 or more, if all of the search range is made invalid(All invalid) (DCNT [3:0]: 1111) by SKILL information, M65727 will make all the motion vector of the said search range invalid. It is possible to limit the range by combining the above mentioned SKILL information.

*SKILL information used by Field/Frame Dual-Prime mode

When the top direction of a search range is made invalid by SKILL information (Search Top), M65727 invalidates the Dual-Prime vector whose vertical component is negative. When the down direction among the search range is specified as invalid by SKILL information (Search Down), M65727 makes the Dual-Prime vector of the search range invalid if its vertical component is positive. When the left direction among the search range is made invalid by SKILL information (Search Left), M65727 invalidates Dual-Prime vector of the search range if its horizontal component is negative. If SKILL information specifies that the right direction among the search range is invalid (Search Right), M65727 invalidates Dual-Prime vector of the search range whose horizontal component is positive.

5.2 Priority Order for Distortion Equivalent Vector

If there are multiple motion vectors which gives the minimum distortion, it is necessary to determine the final motion vector by giving them priority order. M65727 decided on the following priority order according to non-expansion / expansion upper range / expansion lower range.

*Priority order of the distortion equivalent vector for non-expansion

During the non-expansion mode, the distortion equivalent vector has the priority order given by the following equation with Vector (0,0) as the highest priority location.

P (X, Y) = |X| + |Y| The smaller the value of P (X, Y), the higher the priority.

*Priority order of the distortion equivalent vector for expansion upper

During the expansion upper range mode, the distortion equivalent vector uses Vector (0, +8/+16) location as the top priority and uses the priority order given by the following equation.

P (X, Y) = |X| + (-Y+16) The smaller the value of P (X, Y), the higher the priority.

CONTACT MITSUBISHI ELECTRONICS REGARDING DISTRIBUTION 25

DISTRIBUTION RESTRICTED. COPYRIGHT RESERVED 1995

* Priority order of the distortion equivalent vector for expansion lower

During the expansion lower range mode, the distortion equivalent vector uses Vector (0, -8/-16) location as the top priority and uses the priority order given by the following equation.

P (X, Y) = |X| + (Y+16) The smaller the value of P (X,Y), the higher the priority.

Each mode has vectors having the same priority. However, among them, if the motion vector in horizontal direction is close to negative infinity or the same, the side whose dynamic vector in vertical direction is closer to the negative infinity has the priority. Fig. 5.2-1 shows the order of priority for the distortion equivalent vector.

5.3 Detail of Vector Search Range

In case of the non-expansion mode, the motion vector search range of M65727 is ±7.5/±15.5 displacement in vertical direction. When integer precision search mode is specified, the search range is ±7/±15. When the integer precision search mode is specified, the horizontal search ranges become as follows:

±15.5 -> ±15.0, ±31.5 -> ±31.0, ±63.5 -> ±63.0, ±127.5 -> ±127.0

5.4 Formats for External Frame Memory (Search Window Image Memory)

The external frame memory (Search window image memory) used by M65727 has two formats. One is field format and the other is frame format. Field format indicates the state in which field images are stored in succession. One word (32 bits) stores 4 pixels lined up in succession vertically in one field. Frame format indicates that frame images are stored in succession. Within one word (32 bits), four continuous pixels are stored vertically within one frame. (Field pixels of different parity are alternately stored.) It is necessary that the boundary of 4 pixels stored in one word must agree with the boundary of macro block no matter which format is used.

The fo rmat for external frame memory depends on the mode as follows: *Field mode Field format only *Frame mode Field format or frame format *Field Dual-Prime mode Field format only *Frame Dual-Prime mode Field format only

5.5 Expansion of Search Range and Controlling the Validity of Search Range

One M65727 chip is capable of searching ±7.5 pixels in horizontal direction and ±7.5/±15.5 in vertical direction. Fig. 5.5-1 shows the controlling conditions necessary for one chip operation. When the horizontal search range is expanded (±15.5 ~ ±127.5), the following number of chips is needed.

±15.5: 2 chips ±31.5: 4 chips ±63.5: 8 chips

±127.5: 16 chips Fig. 5.5-2 shows the conditions needed for the search range control when horizontal search range is expanded.

The number of chips needed for the expanded vertical search range (±16/±32 or more) is shown below. It is not allowed to use odd number of chips for expanded vertical search range. When ±7.5 is specified for one chip vertical search range,

±16.0: 2 chips

±32.0: 4 chips

±64.0: 8 chips When ±15.5 is specified for one chip vertical search range,

±32.0: 2 chips

±64.0: 4 chips

±128.0: 8 chips Fig. 5.5-3 shows the conditions needed for the control of expanded vertical search range. Fig. 5.5-4

shows the relation between output vertical vector and real vertical vector. When both horizontal and vertical ranges are expanded, the product of the number of chips needed for the above search ranges becomes the number of chips needed.

5.6 Operational Timing

Data (Control) sent to M65727 must be done within pre-determined execution cycles. If data (Control) I/O is performed during different execution cycles , operations of M65727 is not guaranteed. Fig. 5.6-1 shows the operational timing of M65727.

5.7 Treatment of Final MB The M65727 is designed so that it processes successive MB horizontally. So, the special treatment is

required for final MB (when the horizontal search range expansion by multi-chip, each final MB processed in each M65727 requires special treatment). The special treatment means that the user must input every control and data to M65727 as extra (dummy) successive MB will be processing until the out-put of final MB is finished.

5.8 Mode Change during Processing

The sequence of mode change during processing shows below.

· Finish the output of necessary MB in previous mode

· Change the operation mode by mode pins

· Reset the M65727

· Input control and data for new operation mode

6.2 Package The M65727 is housed in plastic 152-pin 28mm x 28mm body HQFP.

Fig. 6.2-1 shows an overview of the package, and fig. 6.2-2 and table 6.2-1 show the pin configuration.

6.3 Thermal Management

The M65727 is designed to operate at 27MHz and 40.5MHz. When 27MHz operation, no thermal management is required (The M65727 can operate in still air.). But, when 40.5MHz, some thermal management is required. The required thermal management is as follows:

· Forced air cooling by 0.5m/s air

· Forced cooling by heat sink (for example: Aluminum table : 28mm x 28mm x 2mm)
