US Patent 7773817 JPEG image processing circuit

A JPEG image processing circuit, capable of performing a JPEG process at high speed, and with low power consumption, and of automatically recovering from a slight trouble, has been disclosed. In the JPEG processing circuit, a JPEG processing section is configured so as to comprise a plurality of JPEG processing cores and a plurality of data storage regions provided in correspondence with the plurality of JPEG processing cores, and when each of the JPEG processing cores performs the process in parallel, the unprocessed data required for the process of each of the JPEG processing cores is stored in each of the data storage regions, corresponding to each of the JPEG processing cores, via a common bus connected to an image memory.
