Computer Hardware Terms, Glossary and Dictionary

Trace cache is an instruction cache in a microprocessor to reduce the required fetch bandwidth on the processing pipeline. Trace cache stores dynamic instruction sequences after they have been fetched and executed in order to follow the instructions at subsequent times without needing to return to the regular cache or the memory for the same instruction sequence. In trace cache, each line stores a snapshot, or trace, of the dynamic instruction stream.
