Abstract
A system for inserting a supplemental micro-operation sequence into a macroinstruction-generated micro-operation flow provides a versatile, flexible mechanism for early pipeline stages of a microprocessor to pass control signals, data, and other information to later pipeline stages. The mechanism is useful to maintain precise timing of a fault model in pipelined processors. A method includes the step of detecting the occurrence of a predetermined uop-inserting event and, responsive thereto, generating a control signal to a uop insertion unit. Responsive thereto, the uop insertion unit supplies signals to a decoder which, responsive thereto, decodes the signal encoded within the signal to provide the inserted uop sequence, which is inserted in a position within the macroinstruction-generated micro-operation flow predetermined by the uop-inserting event.
