Abstract
An external Auxiliary Execution Unit (AXU) interface is provided between a processing core disposed in a first programmable chip and an off-chip AXU disposed in a second programmable chip to integrate the AXU with an issue unit, a fixed point execution unit, and optionally other functional units in the processing core. The external AXU interface enables the issue unit to issue instructions to the AXU in much the same manner as the issue unit would be able to issue instructions to an AXU that was disposed on the same chip. By doing so, the AXU on the second programmable chip can be designed, tested and verified independent of the processing core on the first programmable chip, thereby enabling a common processing core, which has been designed, tested, and verified, to be used in connection with multiple different AXU designs.
