Programmable logic to accelerate dsp function

ABSTRACT

Field Programmable Gate Arrays (FPGA) have become a competitive alternative for high performance DSP applications with computationally intensive functions, previously dominated by general purpose DSP and ASIC devices. In some applications, DSP processors are replaced entirely. While in others, programmable logic works in con-junction with the DSP processor, offloading the computationally-intensive function and freeing the processor for other functions. The benefits of using an FPGA as a DSP Co-processor, as well as, a stand-alone DSP Engine are many. It combines the flexibility of a general-purpose DSP plus the speed, density, and low cost of an ASIC implementation. FPGA gives increased system performance at reduced system cost.
