Abstract
A system may include a memory to store an enhancer to identify a branch instruction, having a miss-prediction rate above a threshold, in an executing thread. The system may additionally include an instruction update unit to modify an operation code (opcode) of the branch instruction, where a modified opcode of a branch instruction indicates an instruction fetch priority for an executing thread. The system may further include a processor, having an instruction decode unit to set a modified instruction fetch priority of the first executing thread based on the modified opcode of the branch instruction, and an instruction fetch unit to retrieve instructions for the first executing thread from the instruction cache at a first rate, the first rate indicated by the modified instruction fetch priority of the first executing thread.
