Abstract :
Presents a VLSI architecture for the evaluation of the (8×8)-point 2-D DCT with on-line arithmetic. The utilization of on-line arithmetic, in combination with an algorithm based on FCT and matrix multiplication, reduces the total hardware maintaining a data rate and a latency similar to approaches based on distributed or parallel arithmetic. The architecture has been integrated in a chip using a 1 μ CMOS technology, occupying an area of 56.7 mm2
