摘要： A system and corresponding method enable payment hardware system module (HSM) communications. The system comprises a multiPayHSM module that transforms an input request, sourced by an application, into a transformed request interpretable by a target payment HSM. The application is integrated, currently, with a current payment HSM that is different from the target payment HSM. The input request is uninterpretable by the target payment HSM. The multiPayHSM module transmits the transformed request to the target payment HSM for processing. The system enables the application, integrated with the different payment HSM, to

摘要： A method and structure for probabilistic shaping and compensation techniques in coherent optical receivers. According to an example, the present invention provides a method and structure for an implementation of distribution matcher encoders and decoders for probabilistic shaping applications. The techniques involved avoid the traditional implementations based on arithmetic coding, which requires intensive multiplication functions. Furthermore, these probabilistic shaping techniques can be used in combination with LDPC codes through reverse concatenation techniques.

摘要： In a vehicular communication network, a communication device generates a physical layer (PHY) preamble of a PHY protocol data unit (PPDU) for transmission in the vehicular communication network. The communication device generates a plurality of PHY data segments of the PPDU, and one or more PHY midambles, each PHY midamble to be transmitted between a respective pair of adjacent PHY data segments, and each PHY midamble including one or more training signal fields. Generating the one or more PHY midambles includes, when the PPDU is to be transmitted according to an extended range (ER) mode, generating each training signal field to include i) a first portion based on a very high throughput long training field (VHT-LTF) defined by the IEEE 802.11ac Standard and ii) a second portion based on the VHT-LTF defined by the IEEE 802.11ac Standard; and transmitting, by the communication device, the PPDU in the vehicular communication network.

摘要： A coordinator communication device operates in a communication network according to a communication protocol that defines repeating time cycles and specifies that each of multiple communication devices is provided a respective transmit opportunity in each time cycle. The coordinator communication device determines a number of follower communication devices in a communication network while the follower communication devices are selecting transmit opportunities using respective initial device identifiers. The coordinator communication device determines a quantity of transmit opportunities to be provided in each of multiple time cycles during which the follower communication devices are selecting transmit opportunities using respective new device identifiers. The coordinator communication device determines the quantity of transmit opportunities at least by using the number of follower communication devices. While the follower communication devices are selecting transmit opportunities using the respective new device identifiers, the coordinator communication device provides the quantity of transmit opportunity periods in each time cycle.

摘要： An optoelectronic device includes a gain medium configured to amplify laser radiation within a given gain band. A resonant optical cavity contains the gain medium and includes first and second reflectors disposed on first and second sides of the gain medium. A comb filter between the first and second reflectors and configured to pass a set of distinct wavelength sub-bands within the gain band, the set of distinct wavelength sub-bands defining a comb. A plurality of optical ring resonators between the first and second reflectors in series with the comb filter have tunable resonant wavelengths in proximity to different, respective wavelength sub-bands of the comb. A control circuit applies respective control voltages to the optical ring resonators so as to tune the respective resonant wavelengths relative to the respective wavelength sub-bands, thereby modulating the sub-bands in the laser radiation that is output from the device.

Each integrated circuit die among the at least one secondary integrated circuit die is mounted on a first surface of the main integrated circuit die, and first metallization connections extend along one or more first through-silicon vias between the functional circuitry and the serial interface circuitry of the at least one secondary integrated circuit die. The first metallization connections may be configured to provide data from the main die to the secondary die, and the secondary die may be configured to communicate data between the integrated circuit device and a remote integrated circuit device. Second metallization connections extend between the serial interface circuitry of and terminals of the main integrated circuit die.

摘要： A pre-scaled accumulated byte count of a port of a network node over a sampling period is scaled with a scaling factor to generate a scaled accumulated byte count. The pre-scaled accumulated byte count represents a total number of bytes in packets transferred by the port. The scaling factor represents a first port-specific attribute of the port and scales a port-specific maximum throughput of the port to a specific maximum port throughput of the network node. An iterative vector encoding method is applied to the scaled accumulated byte count to generate an encoded bit vector comprising bits respectively ordered bit positions. Each set bit of the encoded bit vector represents a respective weighted value of port utilization of the port. The encoded bit vector is stored, at a map location, in an operational statistics map.

摘要： A system and corresponding method isolate work within a virtualized scheduler using tag-spaces. The system comprises a tag-space resource configured to store at least one respective assignment of at least one scheduling group to a given tag-space. The given tag-space defines a given ordering-atomicity domain that isolates, within the virtualized scheduler, (i) work belonging to the at least one scheduling group from (ii) work belonging to at least one other scheduling group, assigned, in the tag-space resource, to a respective tag-space different from the given tag-space. The system further comprises a work scheduler that schedules, for processing, work belonging to the at least one scheduling group and work belonging to the at least one other scheduling group. Such scheduling may have independent ordering and atomicity effectuated therebetween by the given ordering-atomicity domain. Such independency of ordering and atomicity improves quality-of-service of the virtualized scheduler.
