COTS board performs GFLOPS

Wildstar, a family of commercial off-the-shelf (COTS) DSP boards available in VME64X, Compact PCI, and PCI bus models, can perform 11.8 GFLOPS/board (20-bit floating-point FFT) and 23.7 GOPS/board (16-bit fixed-point MACs). It is delivered with a Multi-Radix FFT IP core binary file, which can compute a single 1-k, 32-bit floating-point complex FFT in approximately 25 µs using one of the three Virtex 1000 processing elements on-board. Continuous processing can be streamed together to compute

Continuous processing can be streamed together to compute in approximately 20.5 µs the same 1-k, 32-bit floating-point complex fast Fourier transform at up to 49 Msamples/s, one processing element. If the continuous processing is streamed through two processing elements, the average time to compute the 1-k, 32-bit floating point complex FFT is 10.3 µs, at up to 99 Msamples/s. With three on-board Xilinx Virtex FPGA-type processors, the board can be customized as a parallel-processing system crafted for a particular application running at hardware speed. In addition, the system can be modified while the application is running. Annapolis Micro Systems, 190 Admiral Cochrane Dr., Suite 130, Annapolis, MD 21401; (410) 841-2514; Fax: (410) 841-2518.
