摘要
In a processing unit, a processor core executes instructions in a plurality of simultaneous hardware threads, where multiple of the plurality of hardware threads concurrently execute memory transactions. A transactional memory circuit in the processing unit tracks transaction footprints of the memory transactions of the multiple hardware thread. In response to detecting failure of a given memory transaction of one of the plurality of multiple threads due to an overflow condition, the transactional memory circuit transitions to a throttled operating mode and reduces a number of hardware threads permitted to concurrently execute memory transactions.
