| 20100100688 | LOW-LEVEL CONDITIONAL SYNCHRONIZATION SUPPORT - A low-overhead conditional synchronization instruction operates on a synchronization variable which includes a lock bit, a state specification, and bits for user-defined data. The instruction specifies the memory address of the synchronization variable and a condition. During the synchronization instruction the condition is compared to the state specification within an atomic region. The match succeeds if the condition matches the state specification and the lock bit is clear. The synchronization instruction may operate with a cache under a cache coherency protocol, or without a cache, and may include a timeout operand. | 04-22-2010 |
| 20110145516 | USING BUFFERED STORES OR MONITORING TO FILTER REDUNDANT TRANSACTIONAL ACCESSES AND MECHANISMS FOR MAPPING DATA TO BUFFERED METADATA - A method and apparatus for accelerating a Software Transactional Memory (STM) system is herein described. A data object and metadata for the data object may each be associated with a filter, such as a hardware monitor or ephemerally held filter information. The filter is in a first, default state when no access, such as a read, from the data object has occurred during a pendancy of a transaction. Upon encountering a first access to the metadata, such as a first read, access barrier operations, such as logging of the metadata; setting a read monitor; or updating ephemeral filter information with an ephemeral/buffered store operation, are performed. Upon a subsequent/redundant access to the metadata, such as a second read, access barrier operations are elided to accelerate the subsequent access based on the filter being set to the second state to indicate a previous access occurred. Additionally, mapping of data objects to ephemeral information may be provided by software, such as through a pointer to the ephemeral information associated with the data object; an offset from a base address of the data object to the ephemeral information included associated with the data object; an index into a segment containing the ephemeral information associated with the data object; mapping the data object to the ephemeral information utilizing address arithmetic; and a hash that maps the data object to ephemeral information. | 06-16-2011 |
