Abstract: An electronic circuit includes a clock signal generator configured to deliver a clock signal. A propagation circuit is configured to propagate the clock signal on a plurality of propagation branches. A number of timers are coupled to at least some of the branches. The timers are clocked by corresponding replicas of the clock signal and configured to generate a pulse signal every N pulses of the corresponding replica of the clock signal. A comparator is configured to generate an alarm signal having a first state when two of the pulse signals are phase-offset with respect to one another.

Abstract: An electronic chip includes an integrated optical-wave guide having an end section that extends parallel to a face of the electronic chip. A local groove provided in the electronic chip extends adjacent to the end section of the integrated optical-wave guide. An elongate optical cable includes an optical-wave guide and has an end portion that is at least partially engaged in the local groove. The end portion of the elongate optical cable is configured to support an optical coupling of the optical-wave guide to the integrated optical-wave guide via lateral coupling in a zone of the local groove. An exterior package is provided to house the electronic chip.

Abstract: A method for compressing a data block including sets of homologous components may include selecting a designated component from the data block, and compressing non-designated components with a measurable loss less than or equal to a threshold. The method may further include compressing the designated component based upon at least a selection of values from among the values of the homologous designated components associated with the data of the block.

Abstract: In one example, an integrated circuit includes a register interface that includes a plurality of registers, a bus interface configured to monitor write requests transmitted to the register interface, where the write requests include a target address and data to be written. The bus interface is configured to receive the data to be written to the plurality of registers and register selection signals for selecting a respective register in the plurality of registers. The integrated circuit includes a monitoring circuit configured to monitor the register selection signals between the bus interface and the plurality of registers in order to determine when the data to be written to the plurality of registers is valid.

Abstract: A cover for an electronic package is manufactured by placing an optical insert, having opposite faces and configured to allow light radiation to pass therethrough, between two opposite faces of a cavity of a mold in a position such that said optical faces of the optical insert make contact with said opposite faces of the cavity of the mold. A coating material is injected into the cavity and around the optical insert. The coating material is set to obtain a substrate that is overmolded around the optical insert so as to produce the cover. An electronic package includes an electronic chip mounted to a support substrate with the cover formed by the overmolded substrate mounted to the support substrate.
