<p><P>PROBLEM TO BE SOLVED: To provide a signal processor capable of performing image processing of high performance and high efficiency to the image processing such as encryption/decryption processing of MPEG-4 AVC requiring a large amount of data processing, and to provide an electronic device using the signal processor. <P>SOLUTION: The signal processor is provided with: an instruction parallel processor 100; a first data parallel processor 101; a second data parallel processor 102; a motion detection unit 103 which is exclusive hardware; a deblocking filter processing unit 104; and a variable length encryption/decryption unit 105. By this structure, the signal processor in which loads are distributed to software and hardware, and high throughput and flexibility are attained, and the electronic device using the same are provided in signal processing of image compression/decompression algorithm with much processing amount. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
