Abstract: Networking devices and optical communication systems are provided. In one example, a system is described to include a first physical coding sublayer (PCS) block that incorporates auto-negotiation information into a control block. The control block is transmitted to a second PCS block and the auto-negotiation information is used to enable negotiation between the first and the second PCS blocks.

Abstract: A receiver device includes circuitry to measure an error vector of a pulse amplitude modulation (PAM) sequence in a signal received from a transmitter and control logic coupled to the circuitry. The control logic removes estimated linear components from the measured error vector to generate a non-linear error vector. The control logic further determines, with reference to a set of lookup table (LUT) values, one or more tuning parameters for the PAM sequence based on the non-linear error vector and modifies the set of LUT values according to the one or more tuning parameters. The control logic further provides the modified set of LUT values to the transmitter, which when used by the transmitter to add digital pre-distortion to the PAM sequence, causes the non-linear error to be at least partially removed from the signal.

Abstract: Systems and methods to perform per-register bin packing are disclosed. A system may include a memory and one or more processors coupled to the memory. The one or more processors may determine a first live range of a first variable in a source code and a second live range of a second variable in the source code. The first live range and the second live range may overlap in time during execution of an output code. The one or more processors may generate the output code including a first instruction for the first variable and a second instruction for the second variable. The first instruction may include a first register identifier, a first mask, and a first offset. The second instruction may include the first register identifier, a second mask, and a second offset.

Abstract: Processes for continuous compositional grading for realization of low charge carrier barriers in electro-optical heterostructure semiconductor devices are provided. An example process includes forming, onto one or more semiconductor layers of an electro-optical semiconductor device, a first semiconductor layer associated with a first bandgap value and forming, onto the first semiconductor layer, a grading layer associated with a continuous compositional grading. The example method further includes forming, onto the grading layer, a second semiconductor layer associated with a second bandgap value. The second bandgap value is different than the first bandgap value.

Abstract: Apparatuses, systems, and techniques for detecting that one or more computer programs executed by a host device are subject to malicious activity using a machine learning (ML) detection system. An integrated circuit is coupled to physical memory of a host device via a host interface. The integrated circuit hosts a hardware-accelerated security service to protect one or more computer programs executed by the host device. The security service extracts a set of features from data stored in the physical memory, the data being associated with the one or more computer programs. The security service determines, using the ML detection system, whether the one or more computer programs are subject to malicious activity based on the set of features. The security service outputs an indication of the malicious activity responsive to a determination that the one or more computer programs are subject to the malicious activity.

Abstract: Devices and methods to identify malicious usage of a network device. In at least one embodiment, a network device comprises circuitry for performing a networking function and collecting telemetry data indicative of the performance of the networking function. The network device obtains an inference of a network traffic pattern using a machine learning model, and responds to the inference.

Abstract: A system for cycle-based per-flow packet drop counting. The system comprises a communication network which interconnects nodes including receiver/s, supervisor/s, and sender/s. The sender sends flow/s of packets, via link/s, to the receiver/s. Flow/s are divided into cycles whose lengths are known to sender, receiver and supervisor. The sender adds to each packet indications of: a cycle during which the packet was sent, and whether the packet belongs to a given flow for which packet drops are being counted. The sender reports to the supervisor a number of packets sent during the individual cycle. The receiver reports to the supervisor, by counting indications, for the individual flow, how many packets, sent during the individual cycle, were received. The supervisor computes a difference between the number of packets sent and received, and, for certain difference value/s, implements further action/s.

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.
