Design alternatives for barrel shifters

  title={Design alternatives for barrel shifters},
  author={Matthew R. Pillmeier and Rushmore and Blue Bell and Michael J. Schulte and E. George Walters},
Barrel shifters are often utilized by embedded digital signal processors and general-purpose processors to manipulate data. This paper examines design alternatives for barrel shifters that perform the following functions: shift right logical, shift right arithmetic, rotate right, shift left logical, shift left arithmetic, and rotate left. Four different barrel shifter designs are presented and compared in terms of area and delay for a variety of operand sizes. This paper also examines… CONTINUE READING
