| 概要 |
The progress of both digital signal processing technology and LSI process technology are key factors in spreading digital media products in the market. System LSIs which support the function of video ...and audio data compression are utilized in these systems. This paper presents a case study on the development of an embedded system LSI for MPEG-2 AAC(MPEG-2 Advanced Audio Coding)decoder, based on a soft-core processor and a programming language, called Valen-C. Design results show that we can achieve cost reduction without losing the performance by optimizing the datapath width of the soft-core processor.続きを見る
