TRANSPOSING CIRCUIT FOR MATRIX FORM DATA

摘要

PROBLEM TO BE SOLVED: To provide a transposing circuit for matrix form data with a high processing speed. SOLUTION: During a cycle N (N=4) of the first half, the first input side is selected for all selectors 12i, 12j and 14k and parallel inputted data DI1-DI4 in row direction are shifted from the left of the figure to the right and stored in registers 13i and 13j. At such a time, data in the top registers 131 and 13j are outputted as output data DO1-DO4 in column direction. During the cycle N of the latter half, the second input side is selected for all the selectors 12i, 12j and 12k and the parallel inputted data DI1-DI4 in the row direction are shifted from up of the figure to down and stored in the registers 13i and 13j. At such a time, data in right side registers 13i and 134 are outputted as output data DO1-DO4 in the column direction.
