Complete Stream Fusion for Software-Defined Radio
summary
Strymonas compiles declarative pipelines to generated C with a single main loop, no dynamic allocation, and complete stream fusion, and it implements a high-performance window combinator by specializing buffer layout and duplicating the buffer to make indices constant. Evaluated on FM reception against GNU Radio, it achieves real-time playback on a Raspberry Pi Zero and is twice or more faster on file benchmarks while preserving type safety and single-threaded execution, though output quality matches GNU Radio rather than reducing noise.
