| 摘 要： | 目前MP3技术已经非常成熟,现阶段对于MP3的研究热点是对原始MP3标准在实现过程中的优化以及如何在低成本低功耗的平台上实现MP3.在整个MP3编解码流程中,IMDCT是运算量最大最耗时的部分之一,因此文章提出了一种基于IMCT递归循环实现方法的优化算法.该算法是在已有文献递归算法的基础上进行了改进,并结合硬件系统结构...

| Abstract: | In the application of MP3 technology,the hot topics focus on how to optimize the original MP3 standard and how to realize it on a low cost platform.Concerning that the inverse modified discrete cosine transform(IMDCT) module is one of the largest and most time-consuming computation part in the process of MP3 encoding and decoding,an optimization algorithm based on IMDCT recursive circulation method is put forward in this paper,which is an improved algorithm based on the recursive methods in the existing lit... |
