  • Publication number: 20230195626
    Abstract: A processing system is configured to translate a first cache access pattern of a dispatch of work items to a cache access pattern that facilitates consumption of data stored at a cache of a parallel processing unit by a subsequent access before the data is evicted to a more remote level of the memory hierarchy. For consecutive cache accesses having read-after-read data locality, in some embodiments the processing system translates the first cache access pattern to a space-filling curve. In some embodiments, for consecutive accesses having read-after-write data locality, the processing system translates a first typewriter cache access pattern that proceeds in ascending order for a first access to a reverse typewriter cache access pattern that proceeds in descending order for a subsequent cache access. By translating the cache access pattern based on data locality, the processing system increases the hit rate of the cache.

  • Publication number: 20230055695
    Abstract: Systems, apparatuses, and methods for abstracting tasks in virtual memory identifier (VMID) containers are disclosed. A processor coupled to a memory executes a plurality of concurrent tasks including a first task. Responsive to detecting one or more instructions of the first task which correspond to a first operation, the processor retrieves a first identifier (ID) which is used to uniquely identify the first task, wherein the first ID is transparent to the first task. Then, the processor maps the first ID to a second ID and/or a third ID. The processor completes the first operation by using the second ID and/or the third ID to identify the first task to at least a first data structure. In one implementation, the first operation is a memory access operation and the first data structure is a set of page tables. Also, in one implementation, the second ID identifies a first application of the first task and the third ID identifies a first operating system (OS) of the first task.

  • Patent number: 11521342
    Abstract: A processor receives a request to access one or more levels of a partially resident texture (PRT) resource. The levels represent a texture at different levels of detail (LOD) and the request includes normalized coordinates indicating a location in the texture. The processor accesses a texture descriptor that includes dimensions of a first level of the levels and one or more offsets between a reference level and one or more second levels that are associated with one or more residency maps that indicate texels that are resident in the PRT resource. The processor translates the normalized coordinates to texel coordinates in the one or more residency maps based on the offset and accesses, in response to the request, the one or more residency maps based on the texel coordinates to determine whether texture data indicated by the normalized coordinates is resident in the PRT resource.

  • Publication number: 20220357510
    Abstract: A cable shaving tool including a blade holder having a guide channel extending along the blade holder length. The guide channel includes a cable channel, and a control surface at opposing ends. A removable blade is secured to a blade support surface and the blade edge extends within the guide channel. The blade support and handle are disposed along a central axis. The shaving depth is determined by the differential between: (1) the distance from the cable channel to the bottom surface of the blade holder; and (2) the distance from the control surface to the bottom surface of the blade holder. The handle is secured to the blade holder and extends along the central axis, allowing an operator's hand to be positioned directly over the blade during a cut, apply a downward pressure on the cable to set the blade and then move the tool in a direction parallel to the cable length.

  • Patent number: 11461045
    Abstract: A processing unit is configured to access a first memory that supports atomic operations and a second memory via an interface. The second memory or the interface does not support atomicity of the atomic operations. A trap handler is configured to trap atomic operations and enforce atomicity of the trapped atomic operations. The processing unit selectively provides atomic operations to the trap handler in response to detecting that memory access requests in the atomic operations are directed to the second memory via the interface. In some cases, the processing unit detects a frequency of traps that result from atomic operations that include memory access requests to a page stored in the second memory. The processing unit transfers the page from the second memory to the first memory in response to the trap frequency exceeding a threshold.

  • Publication number: 20220269620
    Abstract: A processor maintains an access log indicating a stream of cache misses at a cache of the processor. In response to each of at least a subset of cache misses at the cache, the processor records a corresponding entry in the access log, indicating a physical memory address of the memory access request that resulted in the corresponding miss. In addition, the processor maintains an address translation log that indicates a mapping of physical memory addresses to virtual memory addresses. In response to an address translation (e.g., a page walk) that translates a virtual address to a physical address, the processor stores a mapping of the physical address to the corresponding virtual address at an entry of the address translation log. Software executing at the processor can use the two logs for memory management.

  • Patent number: 11100004
    Abstract: A processor uses the same virtual address space for heterogeneous processing units of the processor. The processor employs different sets of page tables for different types of processing units, such as a CPU and a GPU, wherein a memory management unit uses each set of page tables to translate virtual addresses of the virtual address space to corresponding physical addresses of memory modules associated with the processor. As data is migrated between memory modules, the physical addresses in the page tables can be updated to reflect the physical location of the data for each processing unit.
