Component descriptions

AE: the Audio Engine, some DSP
AESS: the Audio Engine Subsystem = AE + PMEM + CMEM + SMEM + DMEM
ABE: the Audio Backend = AESS + Interfaces (McBSP, McPDM, McASP, DMIC, Timers, Watchdog)
TWL6040: audio companion (with ADC and DAC) connected through McPDM
HAL: Hardware Abstraction Layer: a Software package that controls the ABE
PMEM: program memory for the AE
DMEM: data memory (to exchange audio samples)
CMEM: coefficient memory
SMEM: sample memory (internal to AESS)
