Title (EN) OPERATION CACHE
(FR) ANTÉMÉMOIRE D'OPÉRATIONS
Abstract:
(EN) 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.
(FR) L'invention concerne un système et un procédé d'utilisation d'une antémémoire d'opérations (op). Le système et le procédé comprennent une antémémoire d'opérations servant à placer en antémémoire des instructions décodées précédemment. L'antémémoire d'opérations comprend une pluralité d'instructions physiquement indexées et étiquetées, permettant le partage d'instructions entre fils. L'antémémoire d'opérations est chaînée par des voies multiples, permettant de servir une pluralité d'instructions dans une ligne d'antémémoire. L'antémémoire d'opérations est conservée entre un stockage partage d'opérations et un stockage immédiat/par déplacement pour maximiser la capacité.
