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.
