Abstract :
In this paper, a cost-effective 2D discrete cosine transform processor using a reconfigurable datapath is described. The proposed architecture uses some multiplexers to reduce computational complexity. This processor operates on 8×8 blocks. Unlike other direct methods, the proposed architecture is regular for VLSI implementation. The proposed 2D DCT processor costs 38598 transistors, with an operating frequency of 100 MHz, using 0.35 μm CMOS technology.
