Abstract :
A single chip MPEG1 decoder was developed. It contains a video decoder, an audio decoder and a system decoder for MPEG1 and also include a CD-ROM decoder for a package media application. The outstanding feature of the chip is its high quality control of MPEG1 system such as buffer management and AV synchronization. The chip basically decodes a MPEG1 stream automatically with minimal support from an external microprocessor. The circuits were designed using a dedicated hardwired logic resulting in a low cost and low power chip. The chip was fabricated in triple metal 0.5 micron CMOS technology. It dissipates about 400 mW power with 54 MHz clock and 3.3 V voltage supply
