20210328758 | PHASE TRANSPORT WITH FREQUENCY TRANSLATION WITHOUT A PLL - A line card in a network box receives a SyncE clock signal and an input SYNC signal. A phase-lock loop (PLL) in the line card receives the SyncE clock signal as a reference clock signal and generates an output SyncE clock signal. The line card regenerates a SYSCLK signal using a digitally controlled oscillator that receives a timing signal from the SyncE PLL and receives a control signal from control logic on the line card. The frequency and phase information contained in the SYNC signal is utilized to control the DCO. The SYSCLK signal is divided to generate an output SYNC signal. The control logic uses the time difference between the input SYNC signal and a SYNC feedback signal to control the DCO to provide a zero delay SYNC output signal. The output SYNC signal and the SYSCLK signal control a time of day counter in the line card. | 2021-10-21 |
20210328759 | FAULT-TOLERANT TIME SERVER FOR A REAL-TIME COMPUTER SYTEM - The invention relates to a method for providing a fault-tolerant global time via a time server in a distributed real-time computer system, wherein the time server comprises four components which are connected to one another via a bi-directional communication channel. At a priori defined periodic, internal synchronization times, each of the four components transmits an internal synchronization message, which is simultaneously transmitted to the other three components, from which each internal computer of a component determines a correction term for the tick counter contained in its component and corrects the reading of the local tick counter by this correction term. | 2021-10-21 |
20210328760 | REAL-TIME COMPUTER SYSTEM AND METHOD FOR CONTROLLING A SYSTEM OR A VEHICLE - The invention relates to a real-time computer system for controlling a technical device, the real-time computer system comprising data acquisition components which are independent of each other, as well as non-secure data processing components for processing sensor data. A time server as well as a first communication system and a second communication system independent of it are provided, the time server periodically sending global time signals to the communication systems. Each data acquisition component has two communication controllers, wherein each data acquisition component is connected by two communication controllers via a communication line to the first communication system, and is connected by another communication controller to the second communication system via a communication line, such that each data acquisition component can transmit its sensor data to each of the two communication systems. | 2021-10-21 |
20210328761 | DETECTION OF LASER FAULT INJECTION ATTACKS ON CRYPTOGRAPHIC DEVICES - Countermeasures against fault injection attacks of a cryptographic integrated circuit, and more specifically laser fault injection attacks are provided. The invention consists in generating sequences of bits belonging to a set of allowed sequences, and storing these sequences on a set of Flip-Flops. Then the sequences stored on the Flip-Flops are checked and, if they do not belong to the allowed sequence, this is the sign that a fault injection attack occurred and caused a bit flip in one of the flip-flops. An alarm signal is then generated. | 2021-10-21 |
