发明名称 MANAGING SPECULATIVE MEMORY ACCESS REQUESTS IN THE PRESENCE OF TRANSACTIONAL STORAGE ACCESSES
摘要 In at least some embodiments, a cache memory of a data processing system receives a speculative memory access request including a target address of data speculatively requested for a processor core. In response to receipt of the speculative memory access request, transactional memory logic determines whether or not the target address of the speculative memory access request hits a store footprint of a memory transaction. In response to determining that the target address of the speculative memory access request hits a store footprint of a memory transaction, the transactional memory logic causes the cache memory to reject servicing the speculative memory access request.
