Digital ICs/DSPs: FIR Filter Tool Generates Low-Or High-Pass Options At Up To 160 MHz

The CoreFIR finite-impulse-response (FIR) intellectual-property (IP) core generator, the latest member of the DirectCore portfolio, is optimized for use with the company's flash- and antifuse-based FPGA families. It generates filters that employ a distributed arithmetic implementation approach to create FPGA-based low- and high-pass digital filters for general signal filtering, detection, and analysis functions. Designed for lower sampling rates, CoreFIR provides a level of flexibility and cost-effectiveness that's more attractive than standard processor or ASIC alternatives. The generator can create FIR filters that operate at more than 160 MHz when implemented on the antifuse-based Axcelerator FPGAs. Pricing starts at $500. A free evaluation version of the CoreFIR generator can be downloaded at www.actel.com/products/ip.
