Patent number: 11966330Abstract: Examples described herein relate to processor circuitry to issue a cache coherence message to a central processing unit (CPU) cluster by selection of a target cluster and issuance of the request to the target cluster, wherein the target cluster comprises the cluster or the target cluster is directly connected to the cluster. In some examples, the selected target cluster is associated with a minimum number of die boundary traversals. In some examples, the processor circuitry is to read an address range for the cluster to identify the target cluster using a single range check over memory regions including local and remote clusters. In some examples, issuance of the cache coherence message to a cluster is to cause the cache coherence message to traverse one or more die interconnections to reach the target cluster.Type: GrantFiled: June 5, 2020Date of Patent: April 23, 2024Assignee: Intel CorporationInventors: Vinit Mathew Abraham, Jeffrey D.

Publication number: 20240074826Abstract: A surgical robot including at least one contact module, a control connection module, at least one first robotic arm, and at least one grip control device. A first transmission member of the control connection module drives the control module through a first transmission connecting member. A first shaft member of the first robotic arm is connected with the first transmission member while the grip control device is connected with the first robotic arm by a transmission interface. A force sensing member of the first robotic arm detects a first reaction force from the contact module so that the first robotic arm sends a feedback control signal to the grip control device to control a grip driving member to generate a force feedback for allowing a grip portion to move. Thereby, users can feel movement of the grip portion caused by the force feedback to avoid accidental iatrogenic injuries.Type: ApplicationFiled: September 14, 2022Publication date: March 7, 2024Inventors: PO-YUN LIU, CHUN-HUNG KUO, CHIH-CHENG CHIEN, YEN-CHIEH WANG

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.
