Abstract
A microprocessor includes a prediction unit (PRU) that predicts a sequence of fetch blocks (FBlks) in a program instruction stream and a macro-op (MOP) cache (MOC) that comprises MOC entries (MEs). An ME is either a single-FBlk ME (SF-ME) that holds MOPs associated with a single FBlk or a multi-FBlk ME (ME-ME) that holds MOPs associated with multiple FBlks. The PRU instructs a fusion engine to build a first MF-ME using the MOPs of a first set of two or more MEs when training fields of the first set of MEs indicate the first set appear as a first consistent sequence and instructs the fusion engine to build a second MF-ME using the MOPs of the first MF-ME and a third ME when the training fields of the first MF-ME indicate the first MF-ME and the third ME appear as a second consistent sequence within the program instruction stream.
