    摘要: A processing system (100) includes a plurality of processor cores (111, 112, 113, 114) and a plurality of private caches (131, 132, 133, 134). Each private cache is associated with a corresponding processor core of the plurality of processor cores and includes a corresponding first set of cachelines. The processing system further includes a shared cache (140) shared by the plurality of processor cores. The shared cache includes a second set of cachelines, and a shadow tag memory (142) including a plurality of entries (216), each entry storing state information (215) for a corresponding cacheline of the first set of cachelines of one of the private caches.
