  • Publication number: 20240211405
    Abstract: A system on chip (SoC) architecture includes an integrated branch and cache hit-miss trace circuit operably coupled to a CPU core, a first trace circuit, and a cache hit-miss trace circuit. Following an occurrence of a cache-fetch instruction: the cache hit-miss trace circuit identifies whether the fetch instruction is a cache-missed instruction, and, in response thereto, sends a cache miss report message that includes a fetch instruction address to the first trace circuit. The first trace circuit is configured to identify whether the fetch instruction is a taken-branch instruction and creates a modified branch trace response message (BTM) that includes the fetch instruction address and sends the modified BTM to a create trace messages circuit. The modified BTM indicates an instruction address of the cache miss.

  • Patent number: 11861403
    Abstract: A thread management circuit of a processing system stores a thread identifier table and a thread completion table. The thread management circuit receives, from a processor core, a request for execution of a portion of an application by an accelerator circuit. The thread management circuit allocates a thread identifier available in the thread identifier table to the processor core for the execution of the portion by the accelerator circuit. The thread management circuit communicates a response and an acceleration request, both including the allocated thread identifier, to the processor core and the accelerator circuit, respectively. The thread management circuit communicates a thread joining response to the processor core based on a received thread joining request and an indication by the thread completion table that the execution of the portion by the accelerator circuit is complete. The executed portion is integrated with the application based on the thread joining response.

  • Patent number: 11474975
    Abstract: Systems and methods receive an asset identification and one or more criterion to at least one of a locale, a market, a target, or an experiment and process a graph having a plurality of sub-graphs to define an asset having one or more desired variants. The asset is then published having the one or more desired variants. Multiple entities are represented as a single entity, which can be used for localization of the asset (e.g., image, video, custom data) or pages. By associating one entity (e.g., an image) across all variations of the entity, the needed storage space for the plurality of assets (e.g., images or videos) is reduced.

  • Patent number: 11354408
    Abstract: A memory controller for a (DRAM) memory processes an (access) command for a target row in the memory, increments a count value for each victim row associated with the target row, and issues a (dummy activate) command for a victim row whose count value reaches a specified threshold. By tracking victim rows instead of target rows, the memory controller can thwart both single-sided and double-sided row-hammer attacks. The memory controller maintains the victim-row addresses and corresponding command counts in a TCAM memory to detect rows that may be prone to row-hammer attacks. If so, then the memory controller issues dummy activate commands to the corresponding memory rows to thwart such row-hammer attacks.

  • Patent number: 11200098
    Abstract: A technique for operating a system including a plurality of processors and a shared resource includes executing a first instruction by a first processor of the plurality of processors. The first instruction generates a reservation of the shared resource for the first processor. The technique includes, after generating the reservation of the shared resource for the first processor, executing a spin lock by the first processor until successful execution of a second instruction acquires a lock of the shared resource. The technique includes disabling interrupts of the first processor in response to an indicator of the successful execution of the second instruction. The first instruction may be a load and reserve instruction and the second instruction may be a conditional store instruction.
