摘要: A coherence controller in hardware of an apparatus in an example detects conflicts on coherence requests through direct, non-broadcast employment of signatures that: summarize read-sets and write-sets of memory transactions; and provide false positives but no false negatives for the conflicts on the coherence requests. The signatures comprise fixed-size representations of a substantially arbitrary set of addresses for the read-sets and the write-sets of the memory transactions.

摘要: A system and related methods for allowing for an increase in the use of spectrum resources through market based mechanisms for spectrum management. Spectrum trading mechanisms are implemented that allow for assignment and allocation decisions to be made by market forces. The system helps moderate an environment where buyers and sellers dynamically determine the assignment of spectrum and its uses.

摘要: Methods and systems for executing nested concurrent threads of a transaction are presented. In one embodiment, in response to executing a parent transaction, a first group of one or more concurrent threads including a first thread is created. The first thread is associated with a transactional descriptor comprising a pointer to the parent transaction.
