ABSTRACT:
A system on chip processor for a multimedia device includes: a pre-processing circuit to convert an external image signal into a compressed input signal for compressing; an encoder/decoder circuit to generate compressed data by compressing the compressed input signal and outputting a coded image signal by decompressing the compressed data; a post-processing circuit to convert the coded image signal into a signal that can be used by an image displaying device; a first system bus connected with pre-processing circuit and post-processing circuit; a second system bus connected with the encoder/decoder circuit; a first bridge DMA circuit to mutually transmit data between first system bus and second system bus; and a controller to control the operation of the circuits.
