Achieves near-peak single-core floating-point performance.

Enables real-time FM reception.

Abstract

Software-Defined Radio (SDR) is widely used not only as a practical application but also as a fitting benchmark of high-performance signal processing. We report using the SDR benchmark -- specifically, FM Radio reception -- to evaluate the recently developed single-thread stream processing library strymonas, contrasting it with the synchronous dataflow system StreamIt. Despite the absence of parallel processing or windowing as a core primitive, strymonas turns out to easily support SDR, offering high expressiveness and performance, approaching the peak single-core floating-point performance, sufficient for real-time FM reception.
