Abstract
An improved shifter design for high-speed data processors is described. The shifter may include a first stage, in which the input bits are shifted by increments of N bits where N>1, followed by a second stage, in which all bits are shifted by a residual amount. A pre-shift may be removed from an input to the shifter and replaced by a shift adder at the second stage to further increase the speed of the shifter.
