Abstract
A system and method for using an operation (op) cache is disclosed. The system and method include an op cache for caching previously decoded instructions. The op cache includes a plurality of physically indexed and tagged instructions allowing sharing of instructions between threads. The op cache is chained through multiple ways allowing service of a plurality of instructions in a cache line. The op cache is stored between a shared operation storage and immediate/displacement storage to maximize capacity.
