Abstract: A network adapter includes a receive (RX) pipeline, a transmit (TX) pipeline, hardware-implemented congestion-control circuitry, and a congestion-control processor. The RX pipeline is configured to receive packets from a network and process the received packets. The TX pipeline is configured to transmit packets to the network. The hardware-implemented congestion-control circuitry is configured to receive, from the TX pipeline and from the RX pipeline, Congestion-Control (CC) events derived from at least some of the packets transmitted to the network and from at least some of the packets received from the network, and to pre-process the CC events. The congestion-control processor is configured to receive the pre-processed CC events from the congestion-control circuitry, and to throttle a transmission rate of the packets transmitted to the network by the TX pipeline responsively to the pre-processed CC events.

Abstract: A system for video encoding includes an acceleration device, to select from a video stream a target video frame and one or more reference frames. The target and reference frames are divided into respective first pluralities of first blocks of a first size and into respective second pluralities of second blocks of a second size, larger than the first size. At least a first map and a second map are computed, including respective motion vectors between each first block in the target video frame and corresponding first blocks in the reference frames, and between each second block in the target video frame and corresponding second blocks in the one or more reference frames. A control unit encodes the target video frame based on at least one of the reference frames by selecting motion vectors from among the motion vectors in the first and second maps.
