Abstract

Soft IP cores can be realized as parameterisable HDL descriptions of circuit architecture where the performance comes from efficiently mapping system functionality. However, special arithmetic operations e.g. division, reciprocal, can restrict this mapping. An approach is presented that maps the system onto foundation operations, multiplication and addition, thereby giving a freer mapping of the full system. The methodology and results are given for a QR-based recursive least squares filter design on a Xilias Virtex 4 FPGA giving a 5 GFLOPS performance.
