Abstract
There is disclosed a barrel shifter for providing efficient wiring therein and a compact composition as compared with conventional ones, in which a low-level-input resistor and a high-level-input resistor are arranged in parallel to each other, and low-level-input-bit lines and high-level-input-bit lines are alternately arranged corresponding to both resistors respectively, the width of both the input and output sides of a barrel-shifter main unit are so arranged as to be substantially the same as the width of the respective resistors substantially defined by wiring width of the respective input-bit lines, and a wiring area from the high-level-input resistor is incorporated in the barrel-shifter main unit as well as a wiring area from the low-level-input resistor.
