Abstract: Due to the multi-layer memory layout and constrained computing resources of low-power audio DSP, programmer suffers difficulties of programming, large overheads, and ineffective performances in migrating to multi-core. ADMP (audio DSP multi-core processing) is a single program multiple data style programming model on APC (audio processing core). It provides light-weight runtime, explicit memory allocation interface, and various interaction methods. Four experimental cases benefit performance boost with ADMP. Experimental results show that ADMP reaches demands of audio applications with little overheads.

Key words: multi-core, low-power, runtime, programming model, audio
