More Information
Summary:A method and apparatus are disclosed for implementing early release of speculatively read data in a hardware transactional memory system. A processing core comprises a hardware transactional memory system configured to receive an early release indication for a specified word of a group of words in a read set of an active transaction. The early release indication comprises a request to remove the specified word from the read set. In response to the early release request, the processing core removes the group of words from the read set only after determining that no word in the group other than the specified word has been speculatively read during the active transaction.
