摘要
Provided is a System on Chip (SoC) system for a multimedia system enabling high-speed transfer of a large amount of multimedia data and a processor to rapidly control a peripheral device. The SoC system includes a processor; a plurality of peripheral devices; a plurality of physically divided memories; a control bus for transferring a control signal from the processor to the peripheral devices and the memories; a data bus for transferring data between the processor, the peripheral devices and the memories; a bridge for coupling the control bus and the data bus to the processor; a plurality of memory controllers coupled to the control bus and controlling each of the memories; a Direct Memory Access (DMA) controller coupled to the data bus and the control bus and controlling data transfer between the peripheral devices and the memories; and a matrix switch coupled between the DMA controller and the memory controllers and enabling simultaneous multiple memory access.
