Abstract:
1. A method comprising: storing a first value at a first field of a first cache tag line when a next occurrence of a first change-of-flow (COF) instruction is presumed to branch and when the end location of the first COF instruction is at a first location of memory; storing a second value at the first field to indicate the next occurrence of the first COF instruction is presumed to branch and when the end location of the first COF instruction is at a second location of memory; storing the first COF instruction at a first storage location of an instruction buffer; determining a second storage location of the instruction buffer that is immediately adjacent to the first storage location based on the first field of the first cache tag line; and storing a target instruction at a branch target address of the first COF instruction at the second storage location.
