摘要
A multiprocessor data processing system includes a plurality of cache memories including a cache memory. The cache memory issues a read-type operation for a target cache line. While waiting for receipt of the target cache line, the cache memory monitors to detect a competing store-type operation for the target cache line. In response to receiving the target cache line, the cache memory installs the target cache line in the cache memory, and sets a coherency state of the target cache line installed in the cache memory based on whether the competing store-type operation is detected.
