RECFEC is a REConfigurable processor optimized for soft implementation of Forward Error Correction (FEC) algorithms. Viterbi, Turbo, Reed-Solomon and LDPC coding algorithms are widely used in wired and wireless standards. The implantation of these algorithms on RECFEC for a multi-mode wireless system is explored and performance metrics are demonstrated. RECFEC is comprised of a pool of processing elements, a processing element controller and memory. Each processing element encapsulates multiple functional units which are optimized for FEC algorithms. Memory includes the configuration and the data buffers. A high bandwidth interconnect network facilitates data movements. Unlike traditional approach to programmable FEC architectures, RECFEC supports multiple algorithms and is instruction-level programmable which results the ultimate flexibility and programmability.
