This paper discusses the design of a combined DCT/IDCT CMOS integrated
circuit for real time processing of HDTV signals. The processor opera
tes on 8 x 8 blocks, Inputs include the blocked pixels that are scanne
d one pixel at a time, and external control signals that control the f
orward or inverse modes of operation, Input pixels have a precision of
9-b for the DCT and 12-b for the IDCT, The layout has been generated
with a 0.8 mu m CMOS library using the Mentor Graphics GDT tools and m
easures under 10 mm(2). Critical path simulation indicates a maximum i
nput sample rate of 100 MHz.
