Abstract

There is provided an integrated circuit for video / audio processing capable of using a design resource obtained in a development of a video / audio device in other type of video / audio device. The integrated circuit for video / audio processing includes: a microcomputer block (2) having a CPU; a stream I / O block (4) for performing I / O of a video and audio stream with an external device; a media processing block (3) for executing media processing including at least one of compression and decompression of video and audio streams inputted to the stream I / O block (4); an AVIO block (5) for converting the video and audio stream subjected to media processing in the media processing block (3) into a video and audio signal for output to an external device or the like; and a memory IF block (6) for controlling data transfer between: the microcomputer block (2), the stream I / O block (4), the media processing block (3), and the AVIO block (5), and an external memory (9).

Description

technical field [0001] The present invention relates to an integrated circuit for video and audio processing, and more particularly, to an integrated circuit for video and audio processing realized as a system LSI used in various applications. Background technique [0002] With the rapid development of digital technology, dynamic image and sound compression and decompression technology in recent years, video and audio equipment such as digital television (DTV), DVD recorder and other digital video recorders (DVR), portable phones, digital cameras, etc. Higher functionality and miniaturization are increasingly sought. For this reason, shortening of the development period has become a major problem at the development site of such video and audio equipment. [0003] Conventionally, in order to support the development of audiovisual equipment, there has been a technique of realizing a plurality of functional blocks required for processing related to audiovisual functions as one...
