摘要：
We have developed the MPEG2 video decoder and the AC-3 audio decoder LSIs for the DVD player. These decoder LSIs together with single 16Mbits SDRAM and D/A converters realize the audio/video processing unit with-the small number of components for the DVD player. The video decoder LSI adopts the RISC controller to control the dedicated processing hardware cores and a design to integrate the frame memory and bitstream buffers into single external memory. The audio decoder LSI adopts the 24bits fixed point DSP core and the dedicated AC-3 accelerator circuit and so on to reduce the software processing amount in AC-3 audio decoding.
