QL5064 QuickPCI Data Sheet
• • • • • • 66 MHz/64-bit PCI Master/Target with Embedded Programmable
Logic and dual Port SRAM
1.0 Device Highlights
High Performance PCI Controller
Extremely Flexible and Configurable
• 64-bit / 66 MHz Master/Target PCI
Controller (automatically backwards
compatible to 33 MHz or/and 32-bits)
• 75 MHz PCI Interface supported for
embedded systems
• PCI Specification v2.2 compliance
• Programmable back-end interface with three
64-bit busses/100 MHz
• Provides full 533 MB/s PCI data transfer
rates (600 MB/s at 75 MHz)
Advanced PCI Features
• DMA Chaining mode for queued DMA
transactions
• Four-channel DMA mastering, plus a SPCI
(Single PCI Access) mode
• Unlimited bursts supported in Master and
Target mode
• Two Master Write FIFOs and two Master
Read FIFOs, each 64-deep and 64 bits wide
• Target Read and Write FIFOs for pre-fetched
reads and multipleposted writes
• Programmable interrupt controller
• I2O compliant under microprocessor control
• 16 Mailbox registers for message passing and
semaphores
• Extended configuration space allowing
Messaged Interrupts,
power management, and future PCI
enhancement support
• Supports processor-less systems, as well as 0
wait-state burst connections to all known
8/16/32/64 bit processors
• Includes non-volatile on-chip configuration
data for total customization
• Independent PCI bus (66 MHz) and local bus
(100 MHz) clocks
• All local interface, control, and glue-logic can
be implemented on chip
• “PCI friendly” pinout simplifies board layout,
supports 4-layer PCI boards
Advanced Master DMA Features
• Programmable DMA Channel Arbitration
Scheme
• SPCI (Single PCI Access) mode may initiate
any PCI Master command
• DMA controller configurable via PCI or
back-end
• DMA Chaining mode allows a linked list of
DMA transfers to occur without user
intervention
High Performance PCI Target
• Write posting FIFO increases performance
with queued transactions
(up to 16 queued writes)
• Any BAR can be defined as pre-fetchable
• Six base address registers supported,
configurable as memory or IO
• Unique “Target Blast Mode” enables high-
performance and very low overhead
streaming data to/from PCI
