Instruction Storage

A method, comprising:

• receiving instructions and respective group identifiers for ones of the received instructions;
• decoding, by decode circuitry, the received instructions;
• storing, by caching circuitry, instructions having a same group identifier as a group in an entry of the caching circuitry;
• and
• retrieving and executing, multiple times by execution circuitry, a group from the caching circuitry, using different input data for each execution of instructions in the group, while the group is stored in the entry of the caching circuitry.

An apparatus, comprising:

• instruction control circuitry configured to:
• group instructions in a thread of instructions to be executed into groups having up to a threshold group size;
• and
• assign a same group identifier to respective instructions in each group;
• caching circuitry that includes a plurality of entries configured to store groups of instructions formed by the instruction control circuitry having up to the threshold group size;
• and
• execution circuitry configured to retrieve and execute a group from the caching circuitry multiple times, using different input data for each execution of instructions the group, while the group is stored in an entry of the caching circuitry.
