Abstract: The present disclosure relates to a depth map sensor including a light source for transmitting light pulses into an image scene; an array of pixel circuits, where each pixel circuit has a photodetector and three asynchronous counters; and a control circuit to control each of a plurality of groups of the pixel circuits of the array to generate a histogram of detection events by accumulating events during eight distinct time intervals between consecutive light pulses transmitted by the light source, such that the histogram comprises eight or more histogram bins.

Abstract: In an embodiment a method for operating an integrated circuit includes sequentially requesting, by a processor of an integrated circuit, different instruction lines; determining, by a first comparator of the integrated circuit, while the processor processes a current instruction line supplied in response to a corresponding request, whether or not at least one of the instructions of the current instruction line is a branch instruction by comparing the at least one of the instructions to reference instructions; executing, by the processor, all instructions of the current instruction line before executing a next instruction line when the at least one instruction is a branch instruction from a program memory of the integrated circuit; and executing, by the processor, all instruction of the current instruction line before executing a next instruction line from first and second volatile memory of the integrated circuit when the at least one instruction is not a branch instruction.

Abstract: A sensor includes pixels each including: a first transistor and a first switch in series between a first node and an internal node of the pixel, a gate of the first transistor being coupled to a second node; a capacitive element, a first terminal of which is connected to the second node; and a plurality of assemblies each including a capacitance in series with a second switch coupled to the internal node. The sensor includes a circuit configured to control, each time a voltage is stored in one of the assemblies, the interruption of a current between the first node and the internal node: by switching a first potential applied to a second terminal of the capacitive element; or by opening the first switch.

Abstract: In an embodiment a device includes a first circuit configured to send a signal comprising numbers successively separated by a constant value to at least one second circuit, each second circuit being in a clock domain different from a clock domain of the first circuit and at least one third circuit configured to determine whether the successive numbers of the signal received by the second circuit are separated by the constant value, wherein the signal is sent to a respective third circuit in each of the clock domains different from the clock domain of the first circuit.

Abstract: A method can be used for programming a group of memory cells of a non-volatile memory device in a programming window that has a duration longer than a programming duration of a memory cell. The programming window is subdivided into a number of time intervals. A programming profile that was determined by simulation while taking into account a reference criterion is retrieved. The programming profile includes, for each time interval, a maximum number of memory cells that can be triggered for programming within each time interval. The memory device is programmed in the programming window, interval-wise, using the programming profile.

Abstract: A CAN device is provided with an encryption function and a decryption function. The encryption function allows messages to be encrypted and put onto a CAN bus. The decryption function allows the messages on the CAN bus to be decrypted. The encryption and decryption functions share keys which change over the course of time.

Abstract: A method for controlling operation of a comparator that includes an amplifier that is connected at an input of the comparator includes neutralizing any change of state of a signal output by the comparator starting from each moment in time at which the change of state of the output signal occurs and lasting for a duration of propagation to compensate for a duration of propagation of signals within the amplifier.
