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.

Abstract: A processor includes a processing core and a cache controller including a read queue and a separate write queue. The read queue is to buffer read requests of the processing core to a non-volatile memory, last level cache (NVM-LLC), and the write queue is to buffer write requests to the NVM-LLC. The cache controller is to detect whether the write queue is full. The cache controller further prioritizes a first order of sending requests to the NVM-LLC when the write queue contains an empty slot, the first order specifying a first pattern of sending the read requests before the write requests, and prioritizes a second order of sending requests to the NVM-LLC in response to a determination that the write queue is full, the second order specifying a second pattern of alternating between sending a write request from the write queue and a read request from the read queue.

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.

Abstract: A processor includes a front end to decode an instruction, an allocator to pass the instruction to a nearest neighbor logic unit (NNLU) to execute the instruction, and a retirement unit to retire the instruction. The NNLU includes logic to determine input of the instruction for which nearest neighbors will be calculated, transform the input, retrieve candidate atoms for which the nearest neighbors will be calculated, compute distance between the candidate atoms and the input, and determine the nearest neighbors for the input based upon the computed distance.

Abstract: Embodiments of the invention provide a method of creating, based on an operating-system-scheduled thread running on an operating-system-visible sequencer and using an instruction set extension, a persistent user-level thread to run on an operating-system-sequestered sequencer independently of context switch activities on the operating-system-scheduled thread. The operating-system-scheduled thread and the persistent user-level thread may share a common virtual address space. Embodiments of the invention may also provide a method of causing a service thread running on an additional operating-system-visible sequencer to provide operating system services to the persistent user-level thread. Embodiments of the invention may further provide apparatus, system, and machine-readable medium thereof.
