A method and system utilized by a multi-processor computer for storing exponent codes is provided. The multi-processor computer includes a plurality of processing elements. Each processing element executes a task having an instruction set. The processing elements are assigned a position in an execution sequence that defines the order in which the processing elements generate their respective outputs. Instruction sets are stored in a computer memory attached to the processing elements. The instruction sets are stored so that the processing elements produce outputs according to the execution schedule. The computer memory can be accessed using a two-dimensional addressing scheme where one dimension designates processing elements and the other designates instructions. Each instruction set includes one or more exponent codes that cause a processing element to raise an input value to a specified power.
