Low-Power High-Modularity Architecture for 8-Point DCT Computation

Abstract:

In this paper, a low-power and high-modularity architecture for 8-point discrete cosine transform (DCT) computation is proposed. The coordinate rotation digital computer (CORDIC) based fast algorithm for DCT computation is derived using matrix decomposition. The sum-angle formula and double-angle formula is used to reduce the CORDIC types. Thus, a high-modularity DCT architecture is obtained by reusing the unique rotation angle CORDIC. The experimental results show that the proposed DCT architecture has lower power and higher modularity than other known architectures.
