A new approach for computing the 2-D DFT and 2-D DCT is presented. A new design of a systolic array for transposed matrix multiplication is also shown in this paper. The new 2-D DFT/DCT avoids the need for the array transposer that was required by earlier implementations, and all processing can be pipelined easily. This approach employs a simple and regular structure that is well suited for VLSI implementation. This array can be easily scaled without modifying the basic control scheme and PE structure.
