PURPOSE: To eliminate the delay between the timing of calculation of parity and timing wherein data become unusable in a computer. CONSTITUTION: This barrel shifter is obtained by dividing input words A and B. Each barrel shifter is equipped with a parity word generating circuit (116) which consists of parity bits combined with one of plural sets of (n) bits and a parity matrix (115) combined with a shift matrix (113) which generates successive (n)-bit groups of parity bits outputted through a parity word output line Q and constituting an output word S. |
