Strymonas is a code-generation–based library (embedded DSL) for fast,
bulk, single-thread in-memory stream processing – with the declarative
description of stream pipelines and yet achieving the speed and memory
efficiency of hand-written state machines. It guarantees complete
stream fusion in all cases.

So far, strymonas has been used on small examples and
micro-benchmarks. In this work, we evaluate strymonas on a large,
real-life application of Software-Defined Radio – FM Radio
reception, – contrasting and benchmarking it against the synchronous
dataflow system StreamIt, and the state-of-the art: GNU Radio.

Strymonas, despite being declarative, single-thread single-core with
no explicit support for SIMD, no built-in windowing or convolution,
turns out to offer portable high performance, well enough for
real-time FM Radio reception. It is on par with (or, on Raspberry Pi
Zero, outstripping) GNU Radio, while providing static guarantees of
complete fusion and type safety.
