ABSTRACT:
A discrete cosine transform/inverse discrete cosine transform or DCT/IDCT integrated circuit capable of performing both DCT and IDCT, includes a processor for processing DCT/IDCT data including, input buffer and arithmetic logic unit for processing incoming data and first pass processed data, multiplier and accumulator unit for performing mathematical operations on DCT/IDCT data, and output buffer and arithmetic logic unit for processing first pass processed data and outgoing data. Also provided is an interleaved random access memory for storing DCT/IDCT data during various stages of processing.
