    Abstract: A neural processor. In some embodiments, the processor includes a first tile, a second tile, a memory, and a bus. The bus may be connected to the memory, the first tile, and the second tile. The first tile may include: a first weight register, a second weight register, an activations buffer, a first multiplier, and a second multiplier. The activations buffer may be configured to include: a first queue connected to the first multiplier and a second queue connected to the second multiplier. The first queue may include a first register and a second register adjacent to the first register, the first register being an output register of the first queue. The first tile may be configured: in a first state: to multiply, in the first multiplier, a first weight by an activation from the output register of the first queue, and in a second state: to multiply, in the first multiplier, the first weight by an activation from the second register of the first queue.

    Abstract: A time-resolving sensor includes a single-photon avalanche diode (SPAD), a logic circuit and differential time-to-charge converter (DTCC) circuit. The SPAD is responsive to a shutter signal to generate an output signal based on detecting an incident photon. The logic circuit generates first and second enable signals. The DTCC includes a capacitor device, first and second switching devices, and an output circuit. The first switching device is responsive to the first enable signal to transfer a charge on the capacitor device to the first floating diffusion. The second switching device is responsive to the second enable signal to transfer a remaining charge on the capacitor device to the second floating diffusion. The output circuit outputs a first voltage that is based on the first charge on the first floating diffusion and a second voltage that is based on the second charge on the second floating diffusion.

    Abstract: A system and a method determines a traveling time for a light pulse between a light pulse source and a pixel of a light sensor array based on a “Find Frequent Items in a Data Steam” technique. In one embodiment, raw timestamp data output from a pixel as a data stream may be temporarily stored, processed twice and then discarded to provide an exact determination of a traveling time estimate. In another embodiment, the raw timestamp data is processed once and discarded to provide an approximate determination of a traveling time estimate. The traveling time estimate may be updated during processing and the most-frequently occurring timestamp is available when processing the data stream is complete. There is no need to keep the raw data in a memory, thereby reducing the memory requirement associated with determining the traveling time of a light pulse.
