1. A method, comprising: providing a data processor having an instruction pipeline, wherein the instruction pipeline has a plurality of instruction pipeline stages, and wherein the plurality of instruction pipeline stages comprise a first instruction pipeline stage and a second instruction pipeline stage; providing a data processor instruction that causes the data processor to perform a first set of computational operations during execution of the data processor instruction; performing the first set of computational operations in the first instruction pipeline stage if the data processor instruction is being executed and a first mode has been selected; and performing the first set of computational operations in the second instruction pipeline stage if the data processor instruction is being executed and a second mode has been selected.
