“…Figure 1 is a block diagram of SoC processor. The SoC architecture consists of dual-core programmable cores: MeidaDSP3200 core [12] and RISC3200 core, ASIC module such as digital video encoder, memory controller, direct memory access (DMA) controller and other interface units. With programmable cores, several different algorithms can be executed in the same hardware, and the functionality of a specific system can be easily upgraded by a change in software.…”

Systems-on-chips provide single-chip solutions in many embedded applications to meet the applications size and power requirements. Media processing such as real-time compression and decompression of video signal is now expected to be the driving force in the evolution of media processor. The MediaSoC322xA 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 the processor cores. The MediaSoC322xA is fabricated in a 0.18um 6LM standard-cell SMIC CMOS technology, occupies about 20mm 2 , and operates at 180MHz. The MeidaSoC322xA are used to audio/video decoder for embedded multimedia application.
