Abstract: A network interface controller includes processing circuitry configured to pair with a local root of trust of a host device connected to the network interface controller and provide a key to an encryption device of the host device that enables the encryption device to encrypt data of one or more host device applications using the key. The encrypted data are stored in host device memory. The processing circuitry is configured to share the key with a remote endpoint and forward the encrypted data from the host device memory to the remote endpoint.

Abstract: Devices, methods, and systems are provided. In one example, a device is described to include a device interface that receives data from at least one data source; a data shuffle unit that collects the data received from the at least one data source, receives a descriptor that describes a data shuffle operation to perform on the data received from the at least one data source, performs the data shuffle operation on the collected data to produce shuffled data, and provides the shuffled data to at least one data target.

Abstract: Systems and methods herein are for a video encoder to be associated with an interface that is to receive, from an application, at least one metric that is associated with a quality preference for video compression to be performed by the video encoder and that is to provide a weight map to enable the video encoder to perform rate-distortion optimization (RDO) for received frames from the application using the weight map to weigh one or more first blocks associated with an individual one of the frames more than one or more second blocks associated with the individual one of the frames.

Abstract: A network adapter includes a network port for communicating with a communication network, a hardware clock, and circuitry. The circuitry is coupled to receive from the communication network, via the network port, one or more time-protocol packets that convey a network time used for synchronizing network devices in the communication network, to align the hardware clock to the network time conveyed in the time-protocol packets, and to make the network time available to one or more time-service consumers running in a host served by the network adapter.
