APPARATUS AND METHOD FOR AUDIO DECODING USING INTER-PROCESS COMMUNICATION

摘要

An audio decoding device using communications between processes and a method thereof are provided to reduce power consumption and operation frequency of audio decode by transmitting data by using individual control protocol between each function block of a decoder. An audio decoding device(10) uses the communications between processes. A parsing unit(12) parses an audio bit stream and outputs a necessary data bit to produce sub band sample data according to the request of a PCM data generating unit. A sub band sample data generating unit(13) generates sub band sample data by using data bit outputted from the parsing unit. A PCM data forming unit(15) requests the parsing unit and stores necessary sub band sample data in the production of next PCM data.
