    • In managing multiprocessor operations, a first processor repetitively reads a cache line wherein the cache line is cached from a line of a shared memory of resources shared by both the first processor and a second processor. Coherency is maintained between the shared memory line and the cache line in accordance with a cache coherency protocol. In one aspect, the repetitive cache line reading occupies the first processor and inhibits the first processor from accessing the shared resources. In another aspect, upon completion of operations by the second processor involving the shared resources, the second processor writes data to the shared memory line to signal to the first processor that the shared resources may be accessed by the first processor. In response, the first processor changes the state of the cache line in accordance with the cache coherency protocol and reads the data written by the second processor. Other embodiments are described and claimed.
    • 在管理多处理器操作时,第一处理器重复地读取高速缓存行,其中高速缓存行从由第一处理器和第二处理器共享的资源的共享存储器的一行缓存。 根据高速缓存一致性协议,在共享存储器线和高速缓存线之间保持一致性。 在一个方面,重复的高速缓存行读取占用第一处理器并且禁止第一处理器访问共享资源。 在另一方面,在由涉及共享资源的第二处理器完成操作之后,第二处理器将数据写入共享存储器线,以向第一处理器通知第一处理器可以访问共享资源。 作为响应,第一处理器根据高速缓存一致性协议改变高速缓存行的状态,并读取由第二处理器写入的数据。 描述和要求保护其他实施例。
