Abstract
Method and systems for creating a sequence of fused instructions. An instruction stream is obtained, and a window of instructions from the instruction stream is examined and one or more groups of instructions that satisfy one or more fusion rules are identified. One or more of the groups of instructions that satisfy the one or more fusion rules are fused and a maximal length data dependence chain in the instruction stream is analyzed by analyzing every node in a dependence graph in a selected window of instructions. Fusion of an instruction group is prevented based on the maximal length data dependence chain.
