Abstract
A microprocessor includes a prediction unit (PRU) that predicts a sequence of fetch blocks (FBlks) in a program instruction stream, a macro-op (MOP) cache (MOC) that comprises MOC entries (MEs), a decode unit, and a fusion engine. Each ME indicates whether it is a single-FBlk ME (SF-ME) that holds MOPs associated with a single FBlk whose architectural instructions have been decoded into the MOPs of the SF-ME or a multi-FBlk ME (ME-ME) that holds MOPs associated with multiple FBlks whose architectural instructions have been decoded into the MOPs of the MF-ME. For each FBlk of one or more FBlks in the program instruction stream: the decode unit decodes the architectural instructions of the FBlk into MOPs, and the fusion engine builds a SF-ME in the MOC using the decoded MOPs, and the fusion engine builds a MF-ME in the MOC using the MOPs of a series of SF-MEs.
