Publication number: 20160019067Abstract: In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.Type: ApplicationFiled: September 26, 2015Publication date: January 21, 2016Inventors: Hong Wang, John P.

Temporal and locality caching hints and prefetching hints are provided to improve system wide caching and prefetching. Message codes for atomic operations to arbitrate ownership between system devices/resources are included to allow efficient access/ownership of shared data. Loose transaction ordering provided for while maintaining corresponding transaction priority to memory locations to ensure data integrity and efficient memory access. Active power sub-states and setting thereof is included to allow for more efficient power management. And, caching of device local memory in a host address space, as well as caching of system memory in a device local memory address space is provided for to improve bandwidth and latency for memory accesses.Type: GrantFiled: November 30, 2012Date of Patent: August 4, 2015Assignee: Intel CorporationInventors: Jasmin Ajanovic, Mahesh Wagh, Prashant Sethi, Debendra Das Sharma, David J.

Publication number: 20140297962Abstract: Instructions and logic provide advanced paging capabilities for secure enclave page caches. Embodiments include multiple hardware threads or processing cores, a cache to store secure data for a shared page address allocated to a secure enclave accessible by the hardware threads. A decode stage decodes a first instruction specifying said shared page address as an operand, and execution units mark an entry corresponding to an enclave page cache mapping for the shared page address to block creation of a new translation for either of said first or second hardware threads to access the shared page. A second instruction is decoded for execution, the second instruction specifying said secure enclave as an operand, and execution units record hardware threads currently accessing secure data in the enclave page cache corresponding to the secure enclave, and decrement the recorded number of hardware threads when any of the hardware threads exits the secure enclave.Type: ApplicationFiled: March 31, 2013Publication date: October 2, 2014Inventors: CARLOS V ROZAS, ILYA ALEXANDROVICH, ITTAI ANATI, ALEX BERENZON, MICHAEL A GOLDSMITH, BARRY E HUNTLEY, ANTON IVANOV, SIMON P JOHNSON, REBEKAH M.
