SOF 2.2 is here

By July 1, 2022Blog

SOF 2.2 includes the following features:

  • The codec adapter is now the module adapter and its API reflects the same API used by the Windows processing modules. This allows 3rd-party processing ISVs to reuse existing code from Windows without any modifications.
  • Optimizations
    • The Frag API has been deprecated which results in a ~1MCPS improvement per component.
    • The Frame API has been added. It pre-calculates block sizes for SIMD/non SIMD use cases which results in a ~0.25MCPS improvement.
  • Processing modules/components
    • A new up mix and down mix module has been added with support for HiFi4; it can up/down mix the number of channels in a stream.
  • Zephyr
    • Native APIs have been for logging, delays, and sleeping. SOF Should be fully Zephyr Native by v2.3.
  • IPC4 additions have been made to enable more advanced use cases and audio endpoints for Windows.
