  • READ AND WRITE MONITORING ATTRIBUTES IN TRANSACTIONAL MEMORY (TM) SYSTEMS
    Publication number: 20100169579
    Abstract: A method and apparatus for monitoring memory accesses in hardware to support transactional execution is herein described. Attributes are monitor accesses to data items without regard for detection at physical storage structure granularity, but rather ensuring monitoring at least at data items granularity. As an example, attributes are added to state bits of a cache to enable new cache coherency states. Upon a monitored memory access to a data item, which may be selectively determined, coherency states associated with the data item are updated to a monitored state. As a result, invalidating requests to the data item are detected through combination of the request type and the monitored coherency state of the data item.

  • EXTENDING CACHE COHERENCY PROTOCOLS TO SUPPORT LOCALLY BUFFERED DATA
    Publication number: 20100169581
    Abstract: A method and apparatus for extending cache coherency to hold buffered data to support transactional execution is herein described. A transactional store operation referencing an address associated with a data item is performed in a buffered manner. Here, the coherency state associated with cache lines to hold the data item are transitioned to a buffered state. In response to local requests for the buffered data item, the data item is provided to ensure internal transactional sequential ordering. However, in response to external access requests, a miss response is provided to ensure the transactionally updated data item is not made globally visible until commit. Upon commit, the buffered lines are transitioned to a modified state to make the data item globally visible.

  • METAPHYSICAL ADDRESS SPACE FOR HOLDING LOSSY METADATA IN HARDWARE
    Publication number: 20100169382
    Abstract: A method and apparatus for metaphysical address space for holding lossy metadata is herein described. An explicit or implicit metadata access operation referencing data address of a data item is encountered. Hardware modifies the data address to a metadata address including a metaphysical extension. The metaphysical extension overlays one or more metaphysical address space(s) on the data address space. A portion of the metadata address including the metaphysical extension is utilized to search a tag array of the cache memory holding the data item. As a result, metadata access operations only hit metadata entries of the cache based on the metadata address extension. However, as the metadata is held within the cache, the metadata potentially competes with data for space within the cache.

  • MEMORY MODEL FOR HARDWARE ATTRIBUTES WITHIN A TRANSACTIONAL MEMORY SYSTEM
    Publication number: 20100169580
    Abstract: A method and apparatus for providing a memory model for hardware attributes to support transactional execution is herein described. Upon encountering a load of a hardware attribute, such as a test monitor operation to load a read monitor, write monitor, or buffering attribute, a fault is issued in response to a loss field indicating the hardware attribute has been lost. Furthermore, dependency actions, such as blocking and forwarding, are provided for the attribute access operations based on address dependency and access type dependency. As a result, different scenarios for attribute loss and testing thereof are allowed and restricted in a memory model.

  • POSTING WEAKLY ORDERED TRANSACTIONS
    Publication number: 20100161907
    Abstract: A processor may comprise a core area, a control unit, an uncore area. The core area may comprise multiple processing cores and line-fill buffers. A first processing core of the core area may store a first weakly ordered transaction in a first line-fill buffer. The firs processing core may offload the first weakly ordered transaction to the extended buffer space provisioned in the uncore area after receiving a request from the uncore area. The first processing core may then de-allocate the first line-fill buffer after the first weakly ordered transaction is offloaded to the extended buffer space. The uncore may then post the first weakly ordered transaction to a memory or a memory system. The control unit may track the first weakly ordered transaction to ensure that the first weakly ordered transaction is posted to the memory or the system.
