MediaSoC: a system-on-chip architecture for multimedia application

The MediaSoC322IA consists of two fully programmable processor cores and integrates digital video encoder. The programmable cores toward a particular class of algorithms: the MediaDSP3200 for RISC/DSP oriented functions and multimedia processing, and the RISC3200 for bit stream processing and control function. Dedicated interface units for DRAM, SDRAM, Flash, SRAM, on screen display and the digital video encoder are connected via a 32-bit system bus with tie processor cores. The MediaSoC3221A is fabricated in a 0.18μm 6LM standard-cell SMIC CMOS technology, occupies about 20 mm², and operates at 180 MHz. The MeidaSoC3221A are used to audio/video decoder for embedded multimedia application.
