Abstract
An ancillary execution unit is interfaced to a primary execution unit of a data processing system where the ancillary unit operates faster than the primary for certain instructions and allows for bypassing the slower unit. The primary execution unit has an instruction input receiving an instruction, an operand input receiving data and an operand output transferring data from the primary execution unit to the data processing system. The ancillary execution unit obtains the instruction from the instruction input, obtains the data from the operand input, performs the function indicated by the instruction to the data, and returns data to the primary execution unit.
