A 250 MHz single-chip multiprocessor integrates four CPUs with multimedia extended instructions on 0.25 /spl mu/m CMOS and consumes 2.4 W at 2.5 V. This chip exploits both coarse- and fine-grained parallelism in A/V signal processing and implements various coded standards such as multi-channel MPEG2 (MP@ML) video decoding.
