Circuits, barrel shifters, and methods of manipulating a bit pattern

摘要

The present invention provides for a circuit comprising: an input operable to receive a bit pattern; a shifter configured to selectively shift the bit pattern; a data output operable to output the bit pattern; and a sign extension operator coupled with the data output and operable to provide a sign extension signal thereto. The present invention additionally discloses a barrel shifter and a method for manipulating a bit pattern.
