Clearspeed will demonstrate during the International Supercomputer Conference (ISC2005), in Heidelberg, Germany, its CSX600 co-processor PCI-X add-in card. It promises to add a floating point performance of 50 Gflops to any PC through two chips integrated in the same board. Performance benefits are limited to floating point operations typical of scientific applications. The CSX600 has 96 Processing Elements (PEs), 128 KB of on-chip scratchpad SRAM, DDR2 DRAM interface and I/O, all interconnected by the ClearConnect on-chip network.
