Architecture Overview

The QL5130 device in the QuickLogic QuickPCI ESP (Embedded Standard Product) family provides a complete and customizable PCI interface solution combined with 57,000 System gates of programmable logic. This device eliminates any need for the designer to worry about PCI bus compliance, yet allows for the maximum 32-bit PCI bus bandwidth (132 MB/s).

The programmable logic portion of the device contains 619 QuickLogic Logic Cells, and 12 QuickLogic Dual-Port RAM Blocks. These configurable RAM blocks can be configured in many width/depth combinations. They can also be combined with logic cells to form FIFOs, or be initialized via Serial EEPROM on power-up and used as ROMs. See the RAM section of this data sheet for more information.

The QL5130 device meets PCI 2.2 electrical and timing specifications and has been fully hardware-tested. This device also supports the Win’98 and PC’98 standards. The QL5130 device features 3.3-volt operation with multi-volt compatible I/Os. Thus it can easily operate in 3.3-volt systems and is fully compatible with 3.3V, 5V and Universal PCI card development.

QL5130 - QuickPCI

PCI Interface

The PCI target is PCI 2.2 compliant and supports 32-bit/33 MHz operation. It is capable of zero waitstate infinite-length read and write transactions (132 MBytes/second). Transaction control is available via the user interface as retries, wait-states, or premature transaction termination may be induced if necessary. The PCI configuration registers are implemented in the programmable region of the device, leaving the designer with ample flexibility to support optional features.

The QL5130 device supports maximum 32-bit PCI transfer rates, so many applications exist which are ideally suited to the device’s high performance. High-speed data communications, telecommunications, and computing systems are just a few of the broad range of applications areas that can benefit from the high speed PCI interface and programmable logic.

PCI Configuration Space

The QL5130 supports customization of required Configuration Registers such as Vendor ID, Device ID, Subsystem Vendor ID, etc.. QuickLogic provides a reference Configuration Space design block.

Since the PCI Configuration Registers are implemented in the programmable region of the QL5130, the designer can implement optional features such as multiple 32-bit Base Address Registers (BARs) and multiple functions, as well as support the following PCI commands: I/O Read, I/O Write, Memory Read, Memory Write, Config Read (required), Configuration Write (required), Memory Read Multiple, Memory Read Line, and Memory Write and Invalidate. Additionally, the device supports Extended Capabilities Registers, Expansion ROMs, power management, CompactPCI hot-plug/hot-swap, Vital Product Data, I

0, and mailbox registers.

PCI address and command decoding is performed by logic in the programmable section of the device. This allows support for any size of memory or I/O space for back-end logic. It also allows the user to implement any subset of the PCI commands supported by the QL5130. QuickLogic provides a reference Address Register/Counter and Command Decode block.

Architecture Overview

The RAM modules in the programmable region can be used to create configurable 32-bit FIFOs. Each 32-bit FIFO can be independently assigned to Target address space for read pre-fetch or write posting. Using the 12 QuickLogic RAM modules, the combinations include:

• 6 independent 64-deep FIFO (2 RAMs each), or

• 3 independent 128-deep FIFOs (4 RAMs each), or

• a combination of the above that requires 12 or less QuickLogic RAM Modules

Asynchronous FIFOs (with independent read and write clocks) are also supported.

QL5130 - QuickPCI

Internal Interface Signal Descriptions

Signals used to connect to the PCI interface in the QL5130 are described below. The direction of the signal indicates if it is an input provided by the local interface (I) or an output provided by the PCI interface (O).

Usr_Addr_WrData[31:0] O Target address, and data from target writes. During all target

accesses, the address will be presented on Usr_Addr_WrData[31:0] and simultaneously, Usr_Adr_Valid will be active. During target write transactions, this por t will also present write data to the PCI configuration space or user logic.

Usr_CBE[3:0] O PCI command and byte enables. During target accesses, the PCI

command will be presented on Usr_CBE[3:0] and simultaneously, Usr_Adr_Valid will be active. During target read or write transactions, this port will present acti ve-low byte-enables to the PCI configuration space or user logic.

Usr_Adr_Valid O Indicates the beginning of a PCI transaction, and that a target

address is valid on Usr_Addr_WrData[31:0] and the PCI command is valid on Usr_CBE[3:0]. When this signal is active, the target address must be latched and decoded to determine if this

address belongs to the device’s memory space. Also, the PCI command must be decoded to determine the type of PCI transaction. On subsequent clocks of a target access, this signal will be low, indicating that an address is NOT present on Usr_Addr_WrData[31:0].

Usr_Adr_Inc O Indicates that the target address should be incremented, because

the previous data transfer has completed. During burst target accesses, the target address is only presented to the back-end logic at the beginning of the transaction (when Usr_Adr_Valid is active), and must therefore be latched and incremented (by 4) for subsequent data transfers. Note that during write transactions, Usr_Adr_Inc indicates valid data on Usr_Addr_WrData[31:0] that must be accepted by the back-end logic (regardless of the state of Usr_Rdy). During read transactions, Usr_Adr_Inc will signal to the back-end that the PCI core is ready to accept data. Usr_Adr_Inc and Usr_Rdy both active during a read transaction signals a data transfer between the FPGA and the PCI core (and that the address counter must be incremented).

Usr_RdDecode I This signal should be driven active when a “user read” command

has been decoded from the Usr_CBE[3:0] bus (while Usr_Adr_Valid is active). This command may be mapped from any of the PCI “read” commands, such as Memory Read, Memory Read Line, Memory Read Multiple, I/O Read, etc.

Usr_WrDecode I This signal should be driven active when a “user write” command

has been decoded from the Usr_CBE[3:0] bus (while Usr_Adr_Valid is active). This command may be mapped from any of the PCI “write” commands, such as Memory Write or I/O Write.

Internal Interface Signal Descriptions

Rev B 5

QL5130 - QuickPCI

Internal Interface Signal Descriptions (Continued)

Usr_Select I This signal should be driven active when the address on

Usr_Addr_WrData[31:0] has been decoded and determined to be within the address space of the device. Usr_Addr_WrData[31:0] must be compared to each of the valid Base Address Registers in the PCI configuration space. Also, this signal must be gated by the Memory Access Enable or I/O Access Enable registers in the PCI configuration space (Command Register bits 1 or 0 at offset 04h).

Usr_Write O This signal will be active throughout a “user write” transaction,

which has been decoded by Usr_WrDecode at the beginning of the transaction. The write-enable for individual double-words of data (on Usr_Addr_WrData[31:0]) during a user write transaction should be generated by logically ANDing this signal with Usr_Adr_Inc.

Cfg_Write O This signal will be active throughout a configuration write

transaction. The write-enable for individual double-words of data (on Usr_Add r_WrData[ 31:0]) during a configuration write transaction should be generated by logically ANDing this signal with Usr_Adr_Inc.

Cfg_RdData[31:0] I Data from the PCI configuration registers, required to be presented

to the PCI core during PCI configuration reads.

Usr_RdData[31:0] I Data from the back-end user logic, required to be presented during

PCI reads. Cfg_CmdReg8 Cfg_CmdReg6

I Bits 6 and 8 from the Command Register in the PCI configuration

space (offset 04h). Cfg_PERR_Det O Parity error detected on the PCI bus. When this signal is active, bit

15 of the Status Register must be set in the PCI configuration

space (offset 04h). Cfg_SERR_Sig O System error asserted on the PCI bus. When this signal is active,

the Signaled System Error bit, bit 14 of the Status Register, must

be set in the PCI configuration space (offset 04h). Usr_TRDYN O Copy of the TRDYN signal as driven by the PCI target interface. Usr_STOPN O Copy of the STOPN signal as driven by the PCI target interface. Usr_Devsel O Inverted copy of the DEVSELN signal as driven by the PCI target

interface. Usr_Last_Cycle_D1 O Indicates that the last transfer in a PCI transaction is occurring. RdPipe_Stat[1:0] O Indicates the number of dwords currently in the read pipeline

(“00” = 0 elements, “01” = 1 element, “11” = 2 elements). This

value is important at the end of a transaction (i.e. when

Usr_Last_Cycle_D1 is active) if non-prefetchable memory is

being read. Non-prefetchable memory is defined as registers or

memory elements whose value changes when they are read.

Examples are status registers which are cleared when they are

read, or FIFO memories, since consecutive reads from the same

address in these elements may not produce the same data values. Usr_Rdy I Used to delay (add wait states to) a PCI transaction when the back

end needs additional time. Subject to PCI latenc y restrictions. Usr_Stop I Used to prematurely stop a PCI target access on the next PCI

clock.

Array of Logic Cells

A wide range of additional features complements the QL5130 device. The FPGA portion of the device is 5 volt and 3.3-volt PCI-compliant and can perform high-speed logic functions such as 160 MHz FIFOs. I/O pins provide individually controlled output enables, dedicated input/feedback registers, and full JTAG capability for boundary scan and test. In addition, the QL5130 device provides the benefits of non-volatility, high design security, immediate functionality on power-up, and a single chip solution.

The QL5130 programmable logic architecture consists of an array of user-configurable logic building blocks, called logic cells, set beneath a grid of metal wiring channels similar to those of a gate array.

Through ViaLink

elements located at the wire intersections, the output(s) of any cell may be programmed to connect to the input(s) of any other cell. Using the programmable logic in the QL5130, designers can quickly and easily customize their

“back-end” design for any number of applications.

FIGURE 4. Logic Cell

RAM Module Features

The QL5130 device has twelve 1,152-bit RAM modules, for a total of 13,824 RAM bits. Using two “mode” pins, designers can configure each module into 64 (deep) x18 (wide), 128x9, 256x4, or 512x2 blocks. See the figure below. The blocks are also easily cascadable to increase their effective width or depth.
