针对MPlayer中的WMA解码耗时进行优化。根据S3C2440平台的特性提出并分析了浮点运算转定点运算和快速除法两种优化方案。实验结果表明：优化后的WMA 解码程序在mini2440平台上的解码效率得到了提高。

The WMA decoding for Mplayer-consuming is optimized .According to S3C2440 platform, two optimiza-tion schemes of floating point arithmetic and fast transfer point division are presented and analysed .Experimental re-sults show that the optimized WMA decoder on the mini 2440 pl...
