Such a system may be compatible with a universal asynchronous receiver transmitter (UART) interface and it may address timing issues by using a protocol having a synchronization frame (sync frame) such that a clock signal may be recovered from the sync frame sent by an off-board master device 202, such as a microcontroller unit 208, to a satellite/slave 211 device. Such a protocol permits elimination of a crystal clock oscillator and phase-locked loop located at satellite, thereby dispensing with an otherwise significant cost.Type: ApplicationFiled: December 13, 2018Publication date: February 6, 2020Inventors: Ruochen Zhang, Wei Xu, Hongyan Wu, Qingjie Ma

Publication number: 20200042033Abstract: An integrated circuits with sequential logic circuitry is provided. The sequential logic circuitry may including latching circuits that receive clock signals from on-chip or off-chip clock sources. The clock signals may exhibit clock skew that is native to the integrated circuit. The natively existing clock skew can be leverage to perform time borrowing to help optimize circuit performance. The desired clock skew can be achieved by intelligent placement of the clock sources and deliberate routing of the clock signals from the clock sources to respective types of clock distribution networks on the integrated circuit.Type: ApplicationFiled: May 17, 2019Publication date: February 6, 2020Inventor: Mark Bourgeault

Publication number: 20200042034Abstract: The disclosed embodiments relate to a technique that uses a modified timing signal to reduce self-induced voltage noise in a synchronous system. During a transient period associated with a deterministic event in the synchronous system, the technique uses a modified timing signal generated based on a normal timing signal as a timing signal for the synchronous system. Outside of the transient period, the technique uses the normal timing as the timing signal for the synchronous system. In some embodiments, the modified timing signal is generated by skipping a pattern of clock transitions in the normal timing signal.Type: ApplicationFiled: August 21, 2019Publication date: February 6, 2020Inventors: Brian S.
