Abstract
In this paper, we propose a set of DSP extensions to the TRIPS ISA and evaluate their performance. By extending the TRIPS ISA with specialized DSP instructions, we offer an explorative look at the interaction conventional specialization techniques (such as SIMD instructions) have with EDGE ISAs. We discuss the implementation and its feasibility and provide non-intrusive compiler support through hand-written library functions. Finally, we evaluate the performance benefits of our extensions with custom library-emphasizing benchmarks and compare our results with those of the industry standard TI c6416 digital signal processor. 1
