ABSTRACT:
A data transposition system reorders successive input groups of N data elements received in column order into corresponding output groups of data elements arranged in row order. The system includes a memory having N data element storage locations and a transposition address generator for repetitively generating a series of different sequences of address signals. The address signals of each sequence are sequentially applied to the memory for reading the data elements stored at the addressed storage locations for providing the output groups of data elements. Each read data element is replaced with the data element of the next input group corresponding in order to the order of the respective address signal within its associated sequence.
