A signal processing system includes means for performing a logic function on a multi-dimensional array of information stored in a memory. Typically, the memory stores two-dimensional video information (pixels), and the logic function is a discrete cosine transform (DCT), or other linear operation. The logic function is performed on both rows and columns of the information. In the prior art, this has required two memory spaces, so that information could be written into one memory while being read out of another memory. In the present invention, a single memory space is used to transpose the information between row and column format,by performing a read-modify-write operation on each memory location in a specified sequence.
