When support for a new platform is being added, certain interfaces required by SOF infrastructure must be implemented. Refer to Platform API documentation for details.

Minimum Platform Requirements

Footprint

DSP platforms can vary from vendor to vendor but in general SOF can run on small platforms like Intel Baytrail DSP with 96kb of instruction RAM and 168kb of data RAM. The SOF footprint can be shrunk to approximately 50kb of TEXT and DATA by fine-tuning runtime features via Kconfig.

DSP Clock Speed

Required DSP clock speed depends on the DSP processing load, so it can vary greatly depending on pipeline topology and the algorithm design that is running. SOF can run several volume passthrough pipelines on the Intel Baytrail DSP at 50MHz using unoptimized C code (SIMD disabled and compiled with GCC).

Toolchain

It’s recommended to use the best optimizing compiler available for your DSP ISA; however, GCC can also be used provided it has your DSP architecture support. GCC will produce functional code, but it may not necessarily be the fastest code for your DSP architecture.
