Abstract: Various embodiments of improved PIN-type photodiodes are provided. In an example embodiment, the PIN-type photodiode includes a p-type contact; an n-type contact; a first absorbing layer disposed between the p-type contact and the n-type contact; and a second absorbing layer disposed between the first absorbing layer and the n-type contact. The first absorbing layer is characterized by a first absorption coefficient and the second absorbing layer is characterized by a second absorption coefficient. The second absorption coefficient is greater than the first absorption coefficient. In another example embodiment, the PIN-type photodiode includes a p-type contact; an n-type contact; a first absorbing layer disposed between the p-type contact and the n-type contact; and a non-absorbing accelerating layer disposed between absorbing layers and non-absorbing drift layer and the n-type contact.

Abstract: A peripheral device includes a bus interface and an Address Translation Service (ATS) controller. The bus interface is to communicate over a peripheral bus. The ATS controller is to communicate over the peripheral bus, including sending address translation requests and receiving address translations in response to the address translation requests, to cache at least some of the address translations in one or more Address Translation Caches (ATCs), to estimate one or more statistical properties of the received address translations, and to configure the one or more ATCs based on the one or more statistical properties.

Abstract: A device, communication system, and method are provided. In one example, a system for routing traffic is described that includes circuits to receive a packet, determine a size of the packet, determine a group of a plurality of groups of the packet based on the size of the packet, determine a port for the packet using a round-robin for the group of the packet, and send the packet via the port. Described systems include circuits to receive packet sizes from an application, initialize packet arbiter circuits based on the sizes, receive a packet associated with the application, determine a size of the packet, associate the packet with one of the packet arbiter circuits, and route the packet to a selected port.

Abstract: A communication device includes a transmitter, a receiver, an echo canceler, and a frequency controller. The transmitter is to transmit a transmitted (TX) signal to a peer communication device over a full-duplex link. The receiver is to receive a received (RX) signal from the peer communication device over the full-duplex link. The echo canceler is to cancel an echo component of the TX signal that is present in the RX signal. The frequency controller is to apply an adjustment to a frequency of the TX signal, the adjustment setting a phase between the TX signal and the RX signal to a value that facilitates cancellation of the echo component by the echo canceler.

Abstract: Systems and methods herein are for a Non-Transparent Bridges (NTBs) that are scalable and configurable to use equally sized or spaced windows and a common lookup database for remapping writes without completions. The equally sized or spaced windows in the address space are addressable by a starting address and a size to support communication between host machines or endpoints. The common lookup database is to allow selection of one the windows associated with a mapping between address spaces of different domains and is also to accept remapping writes through the at least one NTB to modify the mapping without need for a completion to be returned to a source of the remapping writes.

Abstract: Apparatuses, systems, and techniques for classifying a candidate uniform resource locator (URL) as malicious 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 words in a candidate URL and numeric features of a URL structure of the candidate URL. The security service classifies, using the ML detection system, the candidate URL as malicious or benign using the set of features. The security service outputs an indication of a malicious URL responsive to the candidate URL being classified as malicious.

Abstract: Apparatuses, systems, and techniques for detecting that a host device is subject to a distributed denial of service (DDOS) attack using a machine learning (ML) detection system are described. A computing system includes a data processing unit (DPU) with a network interface and a hardware acceleration engine. The DPU hosts a hardware-accelerated security service to extract features from network data and metadata from the hardware acceleration engine and sends the extracted features to the ML detection system. The ML detection system determines whether the host device is subject to a DDOS attack using the extracted features. The ML detection system can send an enforcement rule to the hardware acceleration engine responsive to a determination that the host device is subject to the DDOS attack.
