Embedded Software Optimization for MP3 Decoder Implemented on General-purpose Embedded Processor
Feng Zhao · Journal of Chinese Computer Systems · 2007
This paper proposes a software optimization flow on embedded platform, which mainly includes algorithm optimization, implementation optimization and platform-based optimization. This flow is applied to the optimization of the MP3 decoder on the low power general-purpose embedded processor ARM platform. The last optimized decoder requires 26.2MIPS and 70Kbytes memory space to decode 128Kbps, 44.1Hz joint stereo MP3 format file in real time.
