Figure 3 SupraHD-660/680 DTV System Diagram - FTA Implementation
The SupraHD-660/680 family uses a MIPS32 4KEc™ processor core, described below.
2.1.1 MIPS32TM Central Processor Unit
The CPU used in the SupraHD-660/680 family is based upon the MIPS32 4KEc core, a member of MIPS®
Technologies MIPS32 4KE™ processor core family. It is a high-performance, low-power, 32-bit MIPS RISC core
designed for custom system-on-silicon applications. The 4KEc core implements the MIPS32 Release 2
Architecture with the MIPS16e™ ASE, and the 32-bit privileged resource architecture. The Memory
Management Unit (MMU) contains 4-entry instruction and data Translation Lookaside Buffers (ITLB/DTLB)
and a 16 dual-entry joint TLB (JTLB) with variable page sizes. The synthesizable 4KEc core includes a
Multiply/Divide Unit (MDU) that implements single-cycle MAC instructions, which enable DSP algorithms to
be performed efficiently. This allows 32-bit x 16-bit MAC instructions to be issued every cycle, while a 32-bit x
32-bit MAC instruction can be issued every 2 cycles.
Instruction and data caches are 8 Kbytes in size. In addition, each cache is 2-way set associative. These caches
are augmented by 10 Kbyte Instruction ROM and 8 Kbyte Data ROM respectively.

The SupraHD-660/680 DDR SDRAM interface provides a high-level interface to memory for each SupraHD660/680 internal memory client.
The interface hides details of the memory organization from clients; the memory organization includes the
complex mapping required to improve memory utilization. The SupraHD-660/680 memory clients
communicate with the memory interface through multiple on-chip memory buses. Each memory request
(descriptor) is transmitted using a descriptor bus, and the data associated with the request is transmitted using
a data bus.
Since the performance of an application depends on the available memory bandwidth or latency for active
memory clients, a priority-based arbitration scheme is implemented in the SupraHD-660/680 memory
interface unit to schedule requests from each memory client in the chip, including memory refresh. The
arbitration scheme can be configured through software drivers to optimize for an application. The winning
request from arbitration circuits is presented to the DDR SDRAM interface circuits for access to the DDR
SDRAM chips.
The SupraHD-660/680 SDRAM interface is compatible with memory chips that conform to the Double Data Rate (DDR) SDRAM Specification standardized and published by the JEDEC Solid State Technology
Association. The SupraHD-660/680 SDRAM interface supports DDR-400 and DDR-332 memory chips. A
Delay Lock Loop (DLL) circuits is integrated to support the DDR memory read operation.
1. For 200 MHZ DDR operation, MVDD should be 2.6V, +/- 5%.
The SupraHD-660/680 memory interface supports one rank of DDR SDRAM chips. Subject to the restriction
described above, Table 1 lists the memory options.
Note: The same memory type must be used for every chip of a configuration.

The SupraHD-660/680 UARTs are functionally identical to the 16450 on powerup, and UART A can be placed
in an alternate mode (FIFO mode) to relieve the CPU of excessive software overhead.
In this mode, internal FIFOs are activated allowing 16 bytes (plus 3 bits of error data per byte in the RCVR
FIFO) to be stored in both receive and transmit modes. All logic is on-chip to minimize system overhead and
maximize system efficiency. Two individual interrupts allow signalling of data transfers, one for transmit and
one for receive.
The UART performs serial-to-parallel conversion on data characters received from a peripheral device or a
MODEM, and parallel-to-serial conversion on data characters received from the CPU. The CPU can read the
complete status of the UART at any time during the functional operation. The status information reported
includes the type and condition of the transfer operations being performed by the UART, as well as any error
conditions (parity, overrun, framing, or break interrupt).
The UART includes a programmable baud rate generator that is capable of dividing the timing reference clock
input by divisors of from 1 to (2
Provisions are also included to use this 16x clock to drive the receiver logic.
UART A has complete MODEM-control capability, and a processor-interrupt system. Interrupts can be
programmed to satisfy user requirements, minimizing the computing needed to handle the communications
link.

-1), and producing a 16x clock for driving the internal transmitter logic.
The GPIOs are bidirectional signals used for various applications within the system. Some of the ports, if not
used for their primary function, can be converted to GPIOs and used for different functions. The Four (4)
GPIOs in the SupraHD-660/680 are dedicated to GPIO functionality.
After power-up or reset, the multiplexed GPIO pins wake up as defined by the primary function of each
individual pin. Software can select the functionality of the GPIO pins — either GPIO or a secondary function
— according to the system configuration. The selection is done for each GPIO individually.
• If GPIO functionality is selected, the secondary functionality returns a constant value to the internal
blocks, and outputs are not used.
— When configured as an output, the GPIO pin continuously drives with a high or low level, according
to the bit value of the corresponding register.
— When configured as an input, the GPIO pin value is continuously sampled and stored in the
corresponding register bit. When a specific bit in the direction register changes, the direction change is
immediate.
• If the secondary functionality is active, the GPIO input register remains active (not tied off), and the GPIO
outputs are not used.
Each GPIO pin can also serve as an external interrupt input pin for the SupraHD-660/680. On each GPIO input
there is a programmable edge detection for an interrupt on either the positive or negative edge (or both edges).
Software should disable the GPIO interrupts when updating the GPIO functionality, direction, or edge
selection to avoid false interrupts.

• An external RSET resistor determines the range of YPbPr signal values. This RSET resistor provides a full
dynamic range under an external load of 37.5 ohms on the YPbPr lines.
• YPbPr digital levels are:
— The Y digital levels run from 16 to 235
— The PbPr digital levels run from 16 to 240
• YPbPr (approximate) minimum and maximum voltage amplitudes are:
— Y Sync LOW level is 50 mV.
— Y Blank Level is 350 mV (can be adjusted to 286 mV if necessary).
— Y Sync HIGH level (for tri-level Sync) is 650 mV.
— Y maximum level is 1050 mV.
— PbPr minimum level is 50 mV.
— PbPr maximum level is 750 mV.
• four DACs are shared between the two analog video outputs
• video output from either the Primary DPC or the Secondary DPC

1 Introduction
The AML3278 A/V processor is a completely integrated system targeting all types of Audio/Video decoder
applications that provide connectivity to hard disk, digital camera, MP3 players and other external digital
consumer devices. The target market for AML3278 A/V processor is feature rich DVD players, audio
receivers, DVD/receiver combo players, digital media players, integrated TV media players, portable DVD
players, and portable media players.
The AML3278 combines full function of MPEG-1, MPEG-2 and MPEG-4 decoding, numerous dedicated
and general-purpose peripherals, and a high speed 32-bit host CPU in a single device. The AML3278
has three built-in AMRISC
servo-loop digital signal processing. The AML3278 also provides a high speed interface to external USB
1.1/2.0 chip for connectivity to popular USB devices like hard disk, Flash memory, and digital camera and
MP3 players.
The embedded 32-bits host CPU handles system initialization, DVD navigation, and other system
applications. The AML3278 A/V processor provides a glueless interface to all external components:
ATAPI loaders, USB interface chip, HDMI transmitter chip, audio DACs and memory. Numerous generalpurpose I/O pins can be used to control the front panel display and other miscellaneous tasks. Together,
the embedded host CPU and special glueless interfaces reduce the total system cost for all A/V
applications from any media.
The AML3278 A/V processor features a sophisticated video sub-system that performs video
enhancement and scaling functions. It supports DVD up-scaling capabilities to 720p and 1080i
resolutions for the TV system. In addition, a digital TV interface is created for connecting to external
HDMI or DVI transmitter for 100% digital solution between the DVD and TV systems. The digital TV
interface is designed to work with a companion HDMI transmitter (AML3505) to drive the serial HDMI/DVI
signals.
The video sub-system also integrates an NTSC/PAL TV encoder for traditional analog video outputs like
S-Video, composite, YUV component, RGB and multiple VGA modes. The video encoder also supports
high-quality de-interlaced progressive scan (480p/576p) with full Macrovision support. Contrast
enhancement, hue adjustment, video scaling, video interpolation, pan-scan, letter-box, and zoom are also
supported. In addition, four built in video DACs complement the video encoder further reducing system
cost.
The integrated Audio AMRISC
processing. The micro-coded engine provides support for all existing audio formats and it also has
enough flexibility to accommodate new audio standards. Popular audio formats like MPEG, LPCM, Dolby
AC-3 5.1, HDCD, MP-3 and WMA are supported. In addition, SPDIF (IEC958) input and outputs are
supported. AML3278 also supports the MLP loss-less compression and PCM format for DVD-Audio with
sample rate up to 192 KHz for two channels and 96 KHz for multi-channels.
Since AML3728 supports DVD-Audio, the Audio AMRISC processor also supports MLP and high sample
rate PCM audio formats.
The USB interface provides the necessary high speed interconnections to an external USB chip. The
external USB chip can support up to 2 high-speed USB ports. The AML3278 firmware includes the basic
USB device driver, USB protocol stacks to support bulk and INTR transfer, Hub, Mass-Storage (MS) class,
Picture Transfer Protocol (PTP) and PictBridge protocol. The USB firmware also supports multiple file
systems and includes flexible file transfer functions between USB devices.
