A computing device having a host memory and a host processor for executing instructions out of the host memory; and a network interface card interfacing with the computing device are provided. When there is a cache hit for a read request, the network interface card processes the read request by obtaining data stored from one or both of the host memory and a storage device that the network interface card accesses without involving the host processor and when there are is a cache miss, then the read request is processed by the host processor.

Alternate acknowledgment (ACK) signals in a coalescing Transmission Control Protocol/Internet Protocol (TCP/IP) system are disclosed. In one aspect, a network interface card (NIC) examines packet payloads, and the NIC generates an ACK signal for a sending server before sending a coalesced packet to an internal processor. Further, the NIC may examine incoming packets and send an ACK signal to the internal processor for ACK signals that are received from the sending server before sending the coalesced packet to the internal processor. By extracting and sending the ACK signals before sending the corresponding payloads in the coalesced packet, latency that would otherwise be incurred waiting for the ACK signal is eliminated. Elimination of such latency may improve network performance and may provide power savings.

An electronic device is provided. The electronic device includes a transceiver that communicates with an external electronic device and at least one processor electrically connected with the transceiver. The processor is configured to obtain context information about an operation being performed at the electronic device, to generate identification information about a recommended operation associated with the operation being performed, based on the context information about the operation being performed and to send the identification information about the recommended operation to the external electronic device by using the transceiver.

A System-on-Chip (SoC) performs secure communication operations. The SoC may include a peripheral interface configured to communicate with a host system. The SoC may also include a network interface configured to receive network packets in a secure communication session. The SoC may further include a processor configured to execute an Operating System (OS) software and a secure communication software stack to process at least one received network packet in the secure communication session. In addition, the SoC may include a secure communication engine configured to perform cryptographic operations and generate at least one decrypted packet in the secure communication session. The at least one decrypted packet may be provided to the host system via the peripheral interface.

A controller enables execution of control programs in parallel using a multi-core processor in shorter cycles without causing communication collisions. The controller executes control programs in multiple cycles. In accordance with the priorities assigned to a control program 1 and a control program 2, the controller controls the timing to execute communication associated with the control program 2 without colliding with communication with external devices associated with the control program 1.

A computer-implemented method for creating a data transformation adapter for non-standardized data between a data producer unit and a data consumer unit in a data communication environment is disclosed. The method comprises analyzing first data specifications of the data producer unit, and analyzing second data specifications related to the data consumer unit. The method also comprises matching data attributes of the first specifications with data attributes of the second specifications, generating dynamically a plurality of data transformation adapters using the matched data attributes, selecting a verified adapter ensuring that the matched data attributes of the first specifications and the data attributes of the second specifications are transformed correctly, and generating a minimal data transformation child adapter from the verified adapter based on current dynamic performance requirements of a data consumer, and data attributes currently used by an application of the data consumer unit.

A system, method, and apparatus are provided to facilitate data structures for a datatype engine and provide inline compaction. The system receives, by a network interface card (NIC), a command to read data from a host memory, wherein the command indicates a datatype. The system generates a plurality of read requests comprising offsets from a base address and corresponding lengths based on the datatype. The system issues the plurality of read requests to the host memory to obtain the data from the host memory. The system obtains a byte-mask descriptor corresponding to the datatype. The system performs, based on the obtained data and the byte-mask descriptor, on-the-fly compaction of the obtained data, thereby allowing the NIC to return a requested subset of the obtained data.

Aspects of peripheral device sharing for virtual machines are described. In some aspects, a virtual machine requires access to a peripheral device. The virtual machine is executed in a first host computing system. A table is accessed, and includes a list of peripheral devices, an indication that the peripheral device is connected to a second host computing system, a bandwidth requirement of the peripheral device, and a network bandwidth allocated to the virtual machine. The virtual machine is provided with access to the peripheral device based on a comparison between the bandwidth requirement of the peripheral device, and a threshold percentage of the network bandwidth allocated to the virtual machine.

In accordance with some embodiments, a method is performed at an electronic device with a display, radio frequency (RF) circuitry, and one or more input devices. The device displays a first user interface on the display. While displaying the first user interface, the device detects a pairing request to pair a first peripheral with the electronic device. In response to detecting the pairing request, the device determines whether the first peripheral meets coupling criteria, wherein the coupling criteria require that the first peripheral is coupled to a second peripheral. In accordance with a determination that the first peripheral meets the coupling criteria, the device displays a pairing affordance that initiates pairing of the electronic device with the first peripheral. In accordance with a determination that the first peripheral does not meet the coupling criteria, the device displays information concerning coupling of the first peripheral and the second peripheral.

A method for implementing interface cache dynamic allocation is disclosed in the present invention. The method includes: setting, in advance or when a system is running, the corresponding relationship between a free cache block and an interface required to be accessed in the application, and then sending data packets inputted from the interface to the cache block; when the system is running, if the interface required to be accessed needs to be increased, revoked or modified, adjusting the corresponding relationship between the changed interface and the corresponding cache block in real time. A device and computer storage medium for implementing the method are also disclosed in the present invention.
