Latest audio framework support for Qualcomm Gen 4.5 and Gen 5 automotive SOCs. Audio Weaver now supports bare metal chip level integration and direct configuration of TDM and ALSA interfaces as well as multicore audio processing abstraction.
CHALLENGES
Complex realtime audio routing across SOCs
BSP code revisions to support changes in TDM and ALSA configuration
Difficult to tune audio task allocation across multiple cores
Early audio difficult to design
SOLUTIONS
AWE integrated on all cores using shared memory for synchronization
AWE includes new TDM and ALSA modules to support configuration of these devices
Multicore and thread management is orchestrated in the AWE layout using specific thread modules. Easy to profile and reassign audio functions across cores and HW threads
Core0 AWE integration can support audio frames as small as 250uS
Core0 AWE integration can support audio frames as small as 250uS
Early audio is built into the boot process
KEY FEATURES
Audio Weaver replaces QC Audio Reach framework for more flexible higher performance audio processing
Multicore support across all ARM and Hexagon cores
