Abstract :
Presents a full-custom VLSI design of high-speed 2-D DCT/IDCT processor based on the new class of time-recursive algorithms and architectures which has never been implemented to demonstrate its performance. The authors show that the VLSI implementation of this class of DCT/IDCT algorithms can easily meet the high-speed requirements of HDTV due to its modularity, regularity, local connectivity, and scalability. The design of the 8×8 DCT/IDCT can operate at 50 MHz with a 400 Mbps throughput based on a very conservative estimate under 1.2μ CMOS technology.
