1. A method of imposing instruction execution delay in a coprocessor, comprising: dispatching a set of instructions from an associated processor to the coprocessor, for execution in the coprocessor, wherein the dispatching of an instruction occurs after decoding of the instruction; and delaying execution of the set of instructions in the coprocessor according to a dynamic delay value received from the associated processor, wherein the delaying execution of an instruction occurs after dispatching the instruction for execution; wherein the dynamic delay value comprises a specified pipeline stage selected from one or more execute stages of one or more execution pipelines in the coprocessor wherein execution of the set of instructions is temporarily halted at the specified pipeline stage.
