Abstract: Aspects of the present disclosure relate an apparatus comprising fetch circuitry and instruction storage circuitry. The fetch circuitry is to fetch instructions for execution by execution circuitry. The instruction storage circuitry is to store temporary copies of fetched instructions. The fetch circuitry is configured to preferentially fetch instructions from the instruction storage circuitry. The instruction storage circuitry is configured to, responsive to a storage condition being met, begin storing copies of consecutive fetched instructions, the storage condition indicating a utility of a current fetched instruction; and to, responsive to determining that a number of said stored consecutive instructions has reached a storage threshold, cease storing copies of subsequent fetched instructions.
