Systems and methods described in this disclosure relate, generally, to analyzing electronic circuitry, and more specifically, to analyzing efficiency of clock gating in electronic circuitry. Analysis may include identifying wasted propagation of clock signals by clock gates and/or for a circuitry as a whole. In some embodiments, modified gating logic may be determined that improves clock gating efficiency, for example, by eliminating at least some wasted propagation of clock signals.

Method of clock gate analysis for improved efficiency of electronic circuitry system designs and related systems, methods and devices

The present disclosure relates generally to serial communication links and, more specifically, to events communicated on serial communication links and the timing of those events, for example, to achieve uniform delay among multiple event transmissions.

Devices and methods for transmission of events with a uniform latency on serial communication links

The present disclosure relates generally to serial communication links and, more specifically, to events communicated on serial communication links and the timing of those events. The events may be communicated according to a prioritization process.

Devices and methods for prioritizing transmission of events on serial communication links

In certain embodiments, a method includes wirelessly receiving, by an electrode of a stylus, a signal sent from a touch sensor of a computing device. The received signal includes a data bit and is based on a predefined code sequence. The method also includes producing, by the electrode of the stylus, a derivative signal from the received signal, the derivative signal corresponding to a derivative with respect to time of the received signal. The method further includes performing, by the stylus, a cross-correlation of the derivative signal and an expected-signal pattern, the expected-signal pattern based on a derivative with respect to time of the predefined code sequence, where the cross-correlation produces a cross-correlation signal including one or more cross-correlation pulses. The method also includes determining, by the stylus, based on the cross-correlation signal, that the received signal is associated with the predefined code sequence.

Communication between active stylus and touch sensor

In one embodiment, a method includes receiving a synchronization signal from a computing device and determining a first time associated with detection of a first edge of the synchronization signal. The method also includes determining a second time associated with detection of a second edge of the synchronization signal and determining whether the second time occurs within a first predetermined window of time from the first time. The method further includes, if the second time occurs within the first predetermined window of time from the first time, then determining that the synchronization signal is valid.
