一种高性能的多光驱AUDIO光盘镜像及并行压缩算法
The Arithmetic of High Performance Several CDROM Mirroring Audio CD and Parallelly Compressing
【摘要】 论文分析了光盘镜像和MPEG压缩分别占用系统IO和CPU的特点,将二者有机地结合,充分利用了系统的资源,提出了多个光驱同时镜像Audio光盘且并行压缩算法,并详细讨论了这个算法的设计与实现。
【Abstract】 This thesis mainly analyses the I/O de pl etion and CPU depletion characteristics of Compact Disc mirroring and MPEG compr essing.Then the two factors is combined effectively.And with using the system resources efficiently,an idea of mirroring several Audio CDs simultaneously a nd an algorithm for parallelly compressing is put forward and the designing and implementation of this algorithm is discussed in details.
