Sound Open Firmware
summary
Sound Open Firmware is an open source audio DSP stack and SDK that already runs on Intel Bay Trail/Skylake, Raspberry Pi and recent HiSilicon ports, and is a Linux Foundation project. It supports GCC and Cadence compilers, uses Octave/MATLAB scripts for coefficient generation, and provides an elf-to-DSP image tool with PKCS#1.5 signing. Core firmware can shrink to single-digit kilobytes (practical builds ~40 KB), components include EQ/IIR/FIR/volume, CI runs builds and audio tests via Travis/Docker/alsabat, and runtime EQ coefficient loading is imminent.
