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), and a fusion engine. An ME includes an expected next ME identifier and a counter, updated by the PRU as it predicts the ME in the program instruction stream, that is an indicator of consistency of sequence in the program instruction stream of the ME and an ME indicated by the expected next ME identifier. The PRU detects that each of the counters of N MEs indicate a highly consistent sequence of the N MEs and a final ME identified by the expected next ME identifier of a last ME in the sequence and instructs the fusion engine to use the MOPs of the N MEs and of the final ME to build in the MOC a sequential multi-FBlk ME.
