Abstract

The program control unit of an embedded RISC processor is enhanced with a novel zero-overhead loop controller (ZOLC) supporting arbitrary loop structures with multiple-entry/exit nodes. The ZOLC has been incorporated to an open RISC processor core to evaluate the performance of the proposed unit for alternative configurations of the selected processor. It is proven that speed improvements of 8.4% to 48.2% are feasible for the used benchmarks.
