Abstract: A method of ranging using a time-of-flight (ToF) ranging system includes: receiving, by a processor, a histogram generated by a ToF imager of the ToF ranging system, where the ToF imager is configured to transmit a light pulse for ranging purpose; finding a rising edge of a pulse region in the histogram, where the pulse region corresponds to a reflected light pulse from a target; fine-tuning a location of the rising edge by performing a fitting process between the rising edge and a pre-stored high-solution rising edge; and calculating an estimate of a distance of the target by adding a pre-determined offset to a distance of the rising edge after fine-tuning the location of the rising edge.

Abstract: A safety circuit for a gate driver device receives PWM driving signals, a system supply voltage, as well as first and second safety signals. The circuit includes a first logic circuit configured to propagate the PWM driving signals to produce gate driving signals if the first safety signal is de-asserted, and disable propagation of the PWM driving signals and de-assert the gate driving signals if the first safety signal is asserted. The circuit includes a second logic circuit configured to couple a power supply output node to the system supply voltage to produce a driver supply voltage if the second safety signal is de-asserted, and decouple the power supply output node from the system supply voltage if the second safety signal is asserted.

Abstract: At least one embodiment of a method of manufacturing includes forming a first polycrystalline silicon carbide (SiC) substrate with a sintering process by sintering one or more powdered semiconductor materials. After the first polycrystalline SiC substrate is formed utilizing the sintering process, the first polycrystalline silicon carbide SiC substrate is utilized to form a second polycrystalline SiC substrate with a chemical vapor deposition (CVD) process. The second polycrystalline SiC substrate is formed on a surface of the first polycrystalline SiC substrate by depositing SiC on the surface of the first polycrystalline SiC substrate with the CVD process. As the first and second polycrystalline SiC substrates are made of the same or similar semiconductor material (e.g., SiC), a first coefficient of thermal expansion (CTE) for the first polycrystalline SiC substrate is the same or similar to the second CTE of the second polycrystalline SiC substrate.

Abstract: A neural network is able to reconfigure hardware accelerators on-the-fly without stopping downstream hardware accelerators. The neural network inserts a reconfiguration tag into the stream of feature data. If the reconfiguration tag matches an identification of a hardware accelerator, a reconfiguration process is initiated. Upstream hardware accelerators are paused while downstream hardware accelerators continue to operate. An epoch controller reconfigures the hardware accelerator via a bus. Normal operation of the neural network then resumes.

Abstract: A neural network includes an internal storage unit. The internal storage unit stores feature data received from a memory external to the neural network. The internal storage unit reads the feature data to a hardware accelerator of the neural network. The internal storage unit adapts a storage pattern of the feature data and a read pattern of the feature data to enhance the efficiency of the hardware accelerator.

Abstract: A method and apparatus for aligning electrical contact formations, such as bumps or solder balls, at a first surface of a Wafer Level Chip Scale Package (WLCSP) semiconductor device with electrically conductive pins in an array of electrically conductive pins such as “pogo” pins is provided. The semiconductor device includes, opposite the first surface, a second surface protected by a protection layer. The method includes aligning the semiconductor device to a first alignment member by exposing the protected second surface of the semiconductor device to a chamfered surface in the first alignment member. A second alignment member is aligned to the array of electrically conductive pins. The electrical contact formations are aligned with respect to the array of electrically conductive pins as desired in response to the first and second alignment members being mutually aligned, in response to the semiconductor device being “landed” onto the array of electrically conductive pins.

Abstract: A convolutional accelerator framework (CAF) has a plurality of processing circuits including one or more convolution accelerators, a reconfigurable hardware buffer configurable to store data of a variable number of input data channels, and a stream switch coupled to the plurality of processing circuits. The reconfigurable hardware buffer has a memory and control circuitry. A number of the variable number of input data channels is associated with an execution epoch. The stream switch streams data of the variable number of input data channels between processing circuits of the plurality of processing circuits and the reconfigurable hardware buffer during processing of the execution epoch. The control circuitry of the reconfigurable hardware buffer configures the memory to store data of the variable number of input data channels, the configuring including allocating a portion of the memory to each of the variable number of input data channels.
