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.
Some platforms have been supported by SOF in the past, but are no longer supported in SOF mainline (“main” branch). Below table lists such platforms, the last SOF major release that had support for the platform and the stable branch to use. For every SOF release, a stable branch is created and critical bugfixes can be submitted and released via these stable branches.

Minimum Platform Requirements
Footprint
DSP platforms can vary from vendor to vendor but in general SOF can run on small platforms like Intel Bay Trail 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 Bay Trail 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.
