　　为了将AVS-P3音频解码算法移植到支持定点算法的芯片中，需要将浮点算法转换为定点算法，针对AVS-P3解码器中IMDCT模块加窗算法复杂度较大的问题，在算法定点化的过程中提出一种改进的加窗优化算法，测试结果表明优化后该模块时间和空间复杂度明显下降。

For AVS-P3 audio decoding algorithms writing to the chip which supports fixed-point algorithms ,AVS-P3 audio decoding floating-point algorithms needed to be converted to fixed-point algorithms . Owing to the high complexity of IMDCT module windowing in AVS-P3 decoder algorithm ,we proposed an improved windowing algorithm in this paper .the test results showed that the time and space complexity of the module optimized decreased .
