Abstract
A multi-function high speed barrel shifter comprising three functional levels. The first level performs 1/4 word shifts by a selectable amount. The second level performs 1/8 word shifts on the portion of the word to be shifted and, where desired, fills the remainder of its output with fill bits. The third level performs 1/32 of a data word shift. All shifting and filling are controlled by an input control signal which specifies the operation, direction and shift amount. The circuit is easily complimented in LSI Technology and is easily cascaded to double the size of the data word handled thereby.
