  • Patent number: 11966330
    Abstract: 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.

  • Publication number: 20240074826
    Abstract: 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.

  • Publication number: 20240012772
    Abstract: A physical layer (PHY) is coupled to a serial, differential link that is to include a number of lanes. The PHY includes a transmitter and a receiver to be coupled to each lane of the number of lanes. The transmitter coupled to each lane is configured to embed a clock with data to be transmitted over the lane, and the PHY periodically issues a blocking link state (BLS) request to cause an agent to enter a BLS to hold off link layer flit transmission for a duration. The PHY utilizes the serial, differential link during the duration for a PHY associated task selected from a group including an in-band reset, an entry into low power state, and an entry into partial width state.

  • Patent number: 11860670
    Abstract: Techniques and mechanisms for identifying a memory access resource which is to be a target of an access request. In an embodiment, a processor comprises route tables which are to provide entries corresponding to different respective memory access resources which are coupled to the processor. The processor further comprises a list of items which each correspond to a different respective range of addresses, wherein the items each include an identifier of a respective route table, and an identifier of a respective index offset. Based on an address of the access request, a decoder circuit of the processor searches the list to identify a corresponding one of the items. In another embodiment, the decoder circuit accesses a route table entry, based on the search, to determine how the access request is to be directed to a particular memory access resource.

  • Publication number: 20230325241
    Abstract: Embodiments for allocating shared resources are disclosed. In an embodiment, an apparatus includes a core and a hardware rate selector. The hardware rate selector is to, in response to a first indication that demand for memory bandwidth from the core has reached a threshold value, determine a delay value to be used to limit allocation of memory bandwidth to the core. The hardware rate selector includes a controller having a first counter to count a second indication of demand for memory bandwidth from the first core and a second counter to count expirations of time windows. The first indication is based on a difference between the first counter value and the second counter value.

  • Patent number: 11734174
    Abstract: 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.
