Abstract: An apparatus and method for adaptive spatial accelerated prefetching. For example, one embodiment of an apparatus comprises: execution circuitry to execute instructions and process data; a Level 2 (L2) cache to store at least a portion of the data; and a prefetcher to prefetch data from a memory subsystem to the L2 cache in anticipation of the data being needed by the execution unit to execute one or more of the instructions, the prefetcher comprising a buffer to store one or more prefetched memory pages or portions thereof, and signature data indicating detected patterns of access to the one or more prefetched memory pages; wherein the prefetcher is to prefetch one or more cache lines based on the signature data.

Abstract: Implementations of the disclosure implement timely and context triggered (TACT) prefetching that targets particular load IPs in a program contributing to a threshold amount of the long latency accesses. A processing device comprising an execution unit; and a prefetcher circuit communicably coupled to the execution unit is provided. The prefetcher circuit is to detect a memory request for a target instruction pointer (IP) in a program to be executed by the execution unit. A trigger IP is identified to initiate a prefetch operation of memory data for the target IP. Thereupon, an association is determined between memory addresses of the trigger IP and the target IP. The association comprising a series of offsets representing a path between the trigger IP and an instance of the target IP in memory. Based on the association, an offset from the memory address of the trigger IP to prefetch the memory data is produced.

Abstract: A computer system includes a processor circuit, first and second memory systems, and a configurable memory assistance circuit. The processor circuit is used to run at least one application. The application issues a memory access operation. The configurable memory assistance circuit is in communication with the first and second memory systems and the processor circuit. The configurable memory assistance circuit accelerates the memory access operation for the application using data as the data is in transit between the first and second memory systems.

Abstract: In one embodiment, a processor comprises a processing core, a last level cache (LLC), and a mid-level cache. The mid-level cache is to determine that an idle indicator has been set, wherein the idle indicator is set based on an amount of activity at the LLC, and based on the determination that the idle indicator has been set, identify a first cache line to be evicted from a first set of cache lines of the mid-level cache and send a request to write the first cache line to the LLC.

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: 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.
