Patent number: 11734174Abstract: Described is an low overhead method and apparatus to reconfigure a pair of buffered interconnect links to operate in one of these three modes—first mode (e.g., bandwidth mode), second mode (e.g., latency mode), and third mode (e.g., energy mode). In bandwidth mode, each link in the pair buffered interconnect links carries a unique signal from source to destination. In latency mode, both links in the pair carry the same signal from source to destination, where one link in the pair is “primary” and other is called the “assist”. Temporal alignment of transitions in this pair of buffered interconnects reduces the effective capacitance of primary, thereby reducing delay or latency. In energy mode, one link in the pair, the primary, alone carries a signal, while the other link in the pair is idle. An idle neighbor on one side reduces energy consumption of the primary.Type: GrantFiled: September 19, 2019Date of Patent: August 22, 2023Assignee: Intel CorporationInventors: Huichu Liu, Tanay Karnik, Tejpal Singh, Yen-Cheng Liu, Lavanya Subramanian, Mahesh Kumashikar, Sri Harsha Choday, Sreenivas Subramoney, Kaushik Vaidyanathan, Daniel H.

Publication number: 20230142774Abstract: Architectures and techniques are presented that provide a dynamic, action-driven visual task flow customization to a software-as-a-service (SaaS) platform. A task element, expressing a task workflow can be modeled as a record of an order data model of the development environment. The task workflow can be executing according to a flow state management procedure, e.g., to manage lifecycle. In response to the flow state management procedure, the record can be updated according to a current state of the task element. These task elements can be correlated to an action or other operation of a flow designer module of the SaaS platform, which can leverage native automation.Type: ApplicationFiled: November 5, 2021Publication date: May 11, 2023Inventors: Seyed A.

Publication number: 20200285580Abstract: In one embodiment, an apparatus comprises a processor and a memory controller. The processor is to identify a memory access operation associated with a memory location of a memory. The processor is further to determine that a cache memory does not contain data associated with the memory location. The processor is further to send a memory access notification to a memory controller via a first transmission path. The processor is further to send a memory access request to the memory controller via a second transmission path, wherein the second transmission path is slower than the first transmission path. The memory controller is to receive the memory access notification via the first transmission path, and send a memory activation request based on the memory access notification, wherein the memory activation request comprises a request to activate a memory bank associated with the memory location.Type: ApplicationFiled: June 30, 2017Publication date: September 10, 2020Applicant: Intel CorporationInventors: Lavanya Subramanian, Sreenivas Subramoney, Anant Vithal Nori

Patent number: 10191689Abstract: Systems for page management using local page information are disclosed. The system may include a processor, including a memory controller, and a memory, including a row buffer. The memory controller may include circuitry to determine that a page stored in the row buffer has been idle for a time exceeding a predetermined threshold determine whether the page is exempt from idle page closures, and, based on a determination that the page is exempt, refrain from closing the page. Associated methods are also disclosed.Type: GrantFiled: December 29, 2016Date of Patent: January 29, 2019Assignee: Intel CorporationInventors: Sriseshan Srikanth, Lavanya Subramanian, Sreenivas Subramoney

Patent number: 10176124Abstract: A technology is described for determining an idle page close timeout for a row buffer. An example memory controller may comprise a scoreboard buffer and a predictive timeout engine. The scoreboard buffer may be configured to store a number of page hits and a number of page misses for a plurality of candidate timeout values for an idle page close timeout. The predictive timeout engine may be configured to increment the page hits and the page misses in the scoreboard buffer according to estimated page hit results and page miss results for the candidate timeout values, and identify a candidate timeout value from the scoreboard buffer estimated to maximize the number of page hits to the number of page misses.Type: GrantFiled: April 1, 2017Date of Patent: January 8, 2019Assignee: Intel CorporationInventors: Sriseshan Srikanth, Lavanya Subramanian, Sreenivas Subramoney
