Abstract: A semiconductor device that may include a silicon carbide substrate, a silicon layer disposed on the silicon carbide substrate, and a gate oxide layer disposed on the silicon layer. The silicon layer may be implanted within the silicon carbide substrate. The silicon layer may comprise a thickness of 100 angstroms 5000 angstroms. The silicon layer may contain less than one percent carbon, or may contain a certain percentage of carbon that decreases as a distance from the surface of the silicon carbide substrate increases.

Abstract: A method is disclosed. In various examples, the method may include receiving an instruction for generating a signal comprising a ranging signal and a data signal. The method may also include transmitting, via a terrestrial transmitter for transmitting radio waves having encoded messaging information and timing information for one or more of positioning, navigation and timing, the signal at least partially responsive to the instruction. The signal may include a pulse group comprising a number of ranging pulses and a number of data pulses subsequent to the number of ranging pulses. Respective ones of the number of data pulses may have a phase of either a positive-going phase or a negative-going phase. Information may be encoded using the either positive-going phases or negative-going phases of the data pulses.

Abstract: Systems for authenticating a file are disclosed. A system may include one or more physical devices. The one or more physical devices may select, based on an identifier, a subset of data segments of a computer file for generating a first digest with a cryptographic function. The one or more physical devices may also execute the cryptographic function on the selected subset of data segments of the computer file to generate the first digest. Further, the one or more physical devices may generate an authenticator based on the first digest and a private key. The one or more physical devices may further send the computer file, the identifier, and the authenticator to a secure node. Associated methods and non-transitory machine-readable medium are also disclosed.

Abstract: An apparatus and method for dispatching flash commands. The apparatus includes a plurality of queues, wherein each queue comprises an input to receive a flash command, an output to send a flash command, and an empty signal output to signal when the queue is empty, wherein each queue is assigned a unique, ordered priority. The apparatus includes a selector comprising a plurality of flash command inputs, a flash command output to a flash target, and a selection input, wherein each flash command input is coupled to a corresponding queue output. The apparatus includes an arbiter comprising inputs receiving each queue empty signal and receiving a lock bit from the flash command output of the selector and comprising a selection output coupled to the selection input of the selector. The flash command comprises a lock bit and a plurality of control bits to output to control inputs on a flash target.

Abstract: A method is disclosed. In various examples, the method may include receiving an instruction for generating a ranging signal, and transmitting the ranging signal at least partially responsive to the instruction. In various examples the ranging signal may be transmitted via a terrestrial transmitter for transmitting radio waves having encoded messaging information and timing information for one or more of positioning, navigation and timing. In various examples, the ranging signal may exhibit a first ranging pulse and a second ranging pulse of a pulse group and an encoded transmitter identifier, the transmitter identifier encoded by modulating an inter-pulse interval defined between a start of the first ranging pulse and a start of the second ranging pulse.

Abstract: A controller is provided that includes a serial data (SDA) line interface to connect the controller to an SDA line of a two-wire, shared, serial data bus. The controller includes processing circuitry to sample the SDA line to obtain samples of a voltage level on the SDA line, and monitor the samples. The processing circuitry detects a predetermined number of consecutive ones of the monitored samples at a low voltage level, without a low-to-high transition in the voltage level. The processing circuitry indicates a stuck SDA condition based on the detected, predetermined number of consecutive ones of the monitored samples.

Abstract: A target is provided that includes a serial data (SDA) line interface to connect the target to a SDA line of a two-wire, shared, serial data bus. The target includes processing circuitry to transfer output data on to the SDA line, and monitor data on the SDA line. The processing circuitry compares the data on the SDA line and the output data to detect an error condition when the data on the SDA line and the output data differ. And the processing circuitry performs at least one operation to recover from the detected error condition, including at least one of disabling an output SDA pad buffer of the target that transfers the output data on to the SDA line, or asserting a stop condition on the data bus.

Abstract: A system may include a communication circuit as part of a microcontroller. One or more registers may be configured to enable communication between the communication circuit and one or more external peripherals without a CPU or other processor controlling the communication. The one or more registers may be configured to allow a specific trigger event to initiate communication between the communication circuit and the external peripheral. A DMA controller may transmit data from the communication circuit to a memory and may transmit data from the memory to the external peripheral.
