Fault tolerant scan chain for a parallel processing system

A highly robust fault tolerant scan chain is designed for scanning (and/or controlling a configuration of) a parallel processing system. The scan chain implements parallel redundant scan chains that follow physically diverse paths through the parallel processing system. For each IC under test, a set of redundant TAPs perform a boundary scan, and the test results are combined by voting. The TAPs of each set are physically diverse, in that they are physically located in separate power domains of the parallel processing system. As a result, the scan chain is robust to faults affecting power and/or control signal supply to any one power domain. Respective input and output dummy cells at opposite extreme ends of the scan chain provide a graceful separation and recombination of the redundant parallel scan chains, and so renders the architecture of the scan chain transparent to external boundary scan circuit elements.

A weight post with one threaded end and a number of apertures disposed along its length is inserted through the opening of the uppermost plate. The threaded plug has internal threads for securing over the threaded end of the weight post. The securing plug is positioned over the threaded plug and engages, of a corresponding set of threads, with the threads located within the mounting hole. A number of weights are disposed below the uppermost plate. The lower surface of each weight has a groove which allows a connector pin to pass under the weight and through an aperture of the weight post. The threaded plug is rotated to tighten the assembly to form a single mass of weight and securing plug is rotated to tighten against the threaded plug locking the threaded plug in place. To change the weight, the procedure is reversed.

Cable modem and method of supporting various packet cable protocols

A cable modem in communication with a trivial file transfer protocol (TFTP) server includes a default system and a backup system employing various packet cable protocols. The cable modem boots with the default system, obtains a vendor specific information (VSIF) from the TFTP server, and determines if the VSIF matches with the default system. The cable modem continuously boots with the default system if the VSIF matches with the default system. The cable modem configures the currently default system to be the backup system and configures the currently backup system to be the default system, and reboots with the newly configured default system if the VSIF mismatches with the default system.

Semiconductor structure and method for forming the same

A semiconductor structure includes a substrate, a plurality of conductive features disposed over the substrate, and an isolation structure between conductive features and separating the conductive features from each other. Each of the conductive features includes a first metal layer and a 2D material layer. Another semiconductor structure includes a first conductive feature, a dielectric structure over the first conductive feature, a second conductive feature in the dielectric structure and coupled to the first conductive feature, and a conductive line over and coupled to the second conductive feature. In some embodiments, the conductive line includes a first 3D material layer, a first 2D material layer, and a second 3D material layer. The first 2D material layer is disposed between the first 3D material layer and the second 3D material layer.

Control method, electronic device and non-transitory computer readable storage medium

The disclosure discloses a control method. The control method comprises: determining that a practical operation event is triggered; determining that whether the practical operation event conforms to one of predetermined operation events to generate a determining result; defining predetermined operation event corresponding to the practical operation event as an instant operation interface, and defining an operation interface corresponding to the predetermined operation event as an instant operation interface when the determining result is yes; and displaying the instant operation interface on a touch operation display.

Modem and method supporting various packet cable protocols

A modem includes a communicating module, a multimedia terminal adapter (MTA) module, a parsing module, and a selecting module. The communicating module sends a configuration file request packet to a TFTP server to get configuration files including a file ID. The parsing module parses the configuration files to get the file ID. The selecting module configures the MTA module corresponding to the file ID. The communicating module further communicates with a VoIP network according to a protocol corresponding to the file ID.

Lost circulation test method for expandable geopolymers

The disclosure includes a new test method of evaluating lost circulation prevention with expandable geopolymers. The expandable geopolymer is tested using a permeability plugging tester, slot disk, drilling fluid, and a piston to determine how much fluid is released from the test cell.
