Abstract
In this paper, we propose a modified Malvar algorithm that can transfer the Discrete Hartley Transform (DHT) results to the Discrete Cosine Transform (DCT) by using a one additional CORDIC computing stage. A fast CORDIC-based systolic array is designed with four attractive features the single/double data folding feature; the constructive feature; the co-computing feature; and redundant path computation. Due to the existence of the redundant path, the proposed design also has the capability of error detection.>
