Hybrid Cache State And Filter Tracking Of Memory Operations During A Transaction

A method comprising:

• performing, via a first thread, a read transaction during a transaction of a transactional memory to read a first data and storing the first data in a first cache line of a first cache memory, the first cache line including a tag portion, a data portion, a write-set field, and a read-set field;
• setting a read-set indicator of the read-set field associated with the first thread to indicate that the read transaction occurred during the transaction;
• performing, via the first thread, a write transaction during the transaction to write a second data and storing the second data in a second cache line of the first cache memory, the second cache line including a write-set field;
• and
• setting a write-set indicator of the write set field to indicate that the write transaction occurred during the transaction.
