摘要:
Inspecting a currently fetched instruction group and determining branching behavior of the currently fetched instruction group, allows for intelligent instruction prefetching. A currently fetched instruction group is predecoded and, assuming the currently fetch instruction group includes a branch type instruction, a branch target is characterized in relation to a fetch boundary, which delimits a memory region contiguous with the memory region that hosts the currently fetched instruction group. Instruction prefetching is included based, at least in part, on the predecoded characterization of the branch target.
