  • Patent number: 10877910
    Abstract: Method, apparatus, and program means for a programmable event driven yield mechanism that may activate other threads. In one embodiment, an apparatus includes execution resources to execute a plurality of instructions and a monitor to detect a condition indicating a low level of progress. The monitor can disrupt processing of a program by transferring to a handler in response to detecting the condition indicating a low level of progress. In another embodiment, thread switch logic may be coupled to a plurality of event monitors which monitor events within the multithreading execution logic. The thread switch logic switches threads based at least partially on a programmable condition of one or more of the performance monitors.

  • Patent number: 10452403
    Abstract: 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.

  • Patent number: 10089263
    Abstract: A processor is disclosed and includes at least one core including a first core, and interrupt delay logic. The interrupt delay logic is to receive a first interrupt at a first time and delay the first interrupt from being processed by a first time delay that begins at the first time, unless the first interrupt is pending at a second time when a second interrupt is processed by the first core. If the first interrupt is pending at the second time, the interrupt delay logic is to indicate to the first core to begin to process the first interrupt prior to completion of the first time delay. Other embodiments are disclosed and claimed.

  • Patent number: 9785576
    Abstract: Systems and methods for employing hardware-assisted virtualization for implementing a secure video output path. An example processing system comprises: a memory; a shared interconnect; and a processing core communicatively coupled to the memory via the shared interconnect, the processing core to: initialize a first virtual machine and a second virtual machine; responsive to receiving a memory access transaction initiated by the first virtual machine to access a memory buffer, tag the memory access transaction with an identifier of the first virtual machine; and responsive to receiving a digital content decoder access transaction initiated by the second virtual machine, tag the digital decoder access transaction with an identifier of the second virtual machine.

  • Patent number: 9733937
    Abstract: A method, apparatus, and system are provided for performing compare and exchange operations using a sleep-wakeup mechanism. According to one embodiment, an instruction at a processor is executed to help acquire a lock on behalf of the processor. If the lock is unavailable to be acquired by the processor, the instruction is put to sleep until an event has occurred.

  • Patent number: 9600283
    Abstract: Methods and apparatuses for reducing power consumption of processor switch operations are disclosed. One or more embodiments may comprise specifying a subset of registers or state storage elements to be involved in a register or state storage operation, performing the register or state storage operation, and performing a switch operation. The embodiments may minimize the number of registers or state storage elements involved with the standby operation by specifying only the subset of registers or state storage elements, which may involve considerably fewer than the total number of registers or state storage or elements of the processor. The switch operation may be switch from one mode to another, such as a transition to or from a sleep mode, a context switch, or the execution of various types of instructions.

  • Patent number: 9588771
    Abstract: In one embodiment, the present invention includes a method for directly communicating between an accelerator and an instruction sequencer coupled thereto, where the accelerator is a heterogeneous resource with respect to the instruction sequencer. An interface may be used to provide the communication between these resources. Via such a communication mechanism a user-level application may directly communicate with the accelerator without operating system support. Further, the instruction sequencer and the accelerator may perform operations in parallel. Other embodiments are described and claimed.
