Abstract
In a digital computer system both rotation of bits in a data byte and rotation in combination with additional manipulation, a multifunction permutation switch, in a cyclic mode of operation, connects the input bit lines to the output bit lines so that the sequence of input bits are maintained on the output bit lines when the bits on the input lines are considered as arranged in a circle, and in a non-cyclic mode of operation, connects the input bit lines to the output bit lines in a manner to execute gather operations and spread operations.
