Apparatus and method

Abstract

Apparatus comprises processing circuitry comprising a processing pipeline to perform data processing operations in response to instructions received as successive fetch groups of instructions, the processing pipeline comprising a plurality of successive pipeline stages; indicator circuitry to associate an indication with instructions for handling by the processing circuitry, the indication associated with a given instruction indicating whether the given instruction is a fusible instruction; and instruction fusing circuitry, responsive to the indications associated with instructions at two or more of the plurality of pipeline stages, to selectively perform a fusing operation to fuse a set of instructions at the two or more pipeline stages to generate a respective fused instruction, in which the respective indications associated with each of the set of instructions indicate that the set of instructions are fusible instructions.
