| 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. |
