Based on the implementation of embedded software energy consumption simulation,to the problem of WMA open source decoding code has high energy consumption when working on ARM platform,compiler optimization,source code optimization,algorithm optimization three optimization programs are proposed and analyzed in detail and they are applied to open WMA software decoder.The single and dual channel WMA file are tested and compared which is decoded by the WMA decoder that is optimized or not.The experimental results show that the decoding efficiency of optimized WMA decoder is improved significantly both of single and dual channel WMA file,the energy consumption is decreased more than 90% when working on ARM platform.
