ABSTRACT:
A customizable instruction-set processor (10) implements complex, time-consuming operations by reconfiguring a portion of an instruction execution unit (34) to perform a group of specific functions in hardware rather than implementing a string of operations in software routines. The instruction execution unit (34) has a non-programmable section (46) and a programmable section (48) that receive an opcode and output control signals for controlling a datapath (16). The datapath (16) has a non-programmable datapath (18) and a programmable datapath (32). The programmable section (48) and the programmable datapath (32) are programmed by the user to provide a customizable instruction-set that controls and adds functionality to the customizable instruction-set processor (10).
