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. A FBlk comprises a sequential run of architectural instructions. An ME holds MOPs into which architectural instructions of one or more FBlks are decoded and includes training fields, updated by the PRU as the PRU predicts the ME in the program instruction stream. The PRU, in response to detecting that the training fields of an ME indicate the ME has been a loop body ME that has exhibited a consistent loop iteration count within the program instruction stream, requests the fusion engine to use F copies of the MOPs of the loop body ME to build in the MOC an unrolled loop multi-FBlk ME; F is at least two.
