    摘要: In a processor, a method for speculative permission acquisition for access to a shared memory. The method includes receiving a store from a processor core to modify a shared cache line, and in response to receiving the store, marking the cache line as speculative. The cache line is then modified in accordance with the store. Upon receiving a modification permission, the modified cache line is subsequently committed.
