Fc, a lossless compressor for floating-point streams
Summary
Fc is a lossless floating-point compressor implemented in C for IEEE-754 doubles. It uses adaptive block sizing and a per-block mode competition to select the smallest encoded output, with multi-threading and hardware-accelerated paths (AVX2/SSE). The repository page provides API details, benchmarks against other codecs, CPU requirements, and licensing, highlighting its use for high-performance FP data and time-series workloads.
