A single-chip MPEG-4 audiovisual LSI based on the proposed scalable multiprocessor architecture has been developed for IMT-2000 multimedia applications. The LSI consists of three 16-bit multimedia-extended RISC processors and dedicated hardware accelerators, so as to achieve both low power consumption and high cost-effectiveness. It handles the MPEG- 4 video SP@L1 codec with the QCIF image at 15 frames per second, the AMR speech codec, and the ITU-T H.223 multiplexing at 60MHz consuming only 80mW, which is 33% of the previous design. The MPEG-4 audiovisual LSI was fabricated in 0.18us CMOS technology with quad metal using the embedded DRAM.
