The Model 4954 GateFlow IP Core Libraries leverage Xilinx Virtex FPGAs for high-level performance and reduced development time. The cores include highly optimized fast Fourier transform (FFT) engines and wideband digital downconverters. Each core offers a highly reliable, fully characterized, off-the-shelf computational engine, all ready for deployment in high-performance FPGA-based systems. A 10 × FFT speed improvement enables the cores to handle more than 500-MHz real-time data streams. Free evaluation cores can be downloaded from the company's Web site. The GateFlow IP Core Libraries are available starting at $8995.
