SharcFIN ASIC 64-Bit, 66MHz PCI Bus Interface

BittWare's SharcFIN® ASIC provides a full 64-Bit, 66MHz bus mastering PCI interface and an SDRAM controller to interface the SDRAM and the Virtex-II to the PCI host. The SharcFIN interfaces to the PCI bus at 64-Bits, 66MHz for 528MB/s burst throughput and provides both bus mastering DMA capability and slave access to the SDRAM.

PMC+ Interface

The Tiger-PMC+ is fully compatible with any PMC capable base board. When attached to one of Bittware's PMC+ base boards it also supports BittWare's PMC+ extensions which include four link ports directly to the Virtex-II FPGA. The PMC+ link ports are configurable for BittWare's Tiger ADSP-TS101 base boards and are an ideal way to move high-speed data directly to the DSPs.
