PCIS3BASE is a PCI plug-in board equipped with Xilinx SPARTAN-3 FPGA, PIB expansion-slot and memory. To connext external hardware, a 78-pin HD-SUB connector is available on the board. FPGA configuration is possible at any time without the need to reeboot the Computer (download-software with source source-code included).

A 50 MHz oscillator provides the basic clock for the FPGA and the local bus of the PCI-bridge. Optional, additional clocks can be provides by plug-in boards. One slot for plug-in boards is available. It is connected to the FPGA and to the HD-SUB connector by 100-pin connectors respectively. User-specific hardware-extensions as ADC's, DAC's, PHY's or other devices can be easily added this way.

The busmaster PCI interface is implemeted using a dedicated device, the PLX PCI-9056. No PCI core is needed in your FPGA design. No detailed knowledge about the PCI-bus is needed to transfer data beween the FPGA and the user-software running on the PC. The example design coming with the board shows how to implement communication using the Wishbone interface The FPGA-device is connected to fast 32-MByte SDRAM memory. It can be used in own designs.
