ABSTRACT:
An MPEG-2 decoder circuit achieves smaller circuit area, and hence lower cost, by using circuitry, including ROMs, designed to implement residue arithmetic to calculate discrete cosine transforms in a pipelined or iterative fashion. A variable-length decoder based on ROM-like PLAs parses the stream of data to separate audio from video data and to direct the necessary operations on the data elements. The decoder and data flow through the system are controlled by a conditional MOVE processor, which is implemented as a data memory.
