Abstract
A first and second barrel shifters (BSA0 and BSA1) are connected directly without intervening any pipe-line register between the two, and a sense amplifier (R3A0) is provided at an output side of the second barrel register (BSA1). Further, the circuit patterns of the first and second barrel shifters are formed being overlapped with each other in such a way that the elements of one of the first and second barrel shifters are formed at the dead space of the other of the two barrel shifters to reduce the pattern area. In the shift circuit and the variable-length decoder, the data lines of the barrel shifters can be minimized in size and width.
