Virtex FPGA Module DB-VS

The FPGA module DB-VS integrates Xilinx FPGAs of the first Virtex an Virtex-E generation into the RAPTOR systems. Memory-intensive applications are supported by 128 MByte SDRAM, tightly coupled to the FPGA. Like all other FPGA-based RAPTOR extension modules, DB-VS enables partial reconfiguration of the embedded FPGAs at run-time. Reconfiguration is performed either by the host computer via PCI/USB or by other system components within the RAPTOR environment.
