Abstract
A central processing unit includes a register file having a plurality of read ports, a first execution unit having a first plurality of input ports, and logic operable to selectively couple different arrangements of the read ports to the input ports. A method for reading operands from a register file having a plurality of read ports by a first execution unit having a first plurality of input ports includes scheduling an instruction for execution by the first execution unit and selectively coupling a particular arrangement of the read ports to the input ports based on a type of the instruction.
