Abstract:
Methods and systems that identify and power up ways for future instructions are provided. A processor includes an n-way set associative cache and an instruction fetch unit. The n-way set associative cache is configured to store instructions. The instruction fetch unit is in communication with the n-way set associative cache and is configured to power up a first way, where a first indication is associated with an instruction and indicates the way where a future instruction is located and where the future instruction is two or more instructions ahead of the current instruction.
