An evaluation and prototyping kit is available for the firm's 66-MHz, 64-bit, zero-wait-state PCI soft core. The EVPCI66 kit supports a throughput of 528 Mbytes/s and gives designers a means of examining the core's capabilities in their designs before making a commitment to silicon. The combination of zero wait states and a soft-core implementation is said to provide extremely high performance and maximum design flexibility. The board includes two 72-pin SIMM sockets that can be populated with standard SRAM or SDRAM. This enables designers to evaluate the PCI core as it executes high-bandwidth transfers from the PCI bus to memory. Users can also plug custom daughterboards into the SIMM slots to prototype their own applications.
