Abstract: Embodiments of the present disclosure provide systems and methods for maintaining timing precision in different operating modes of a device (e.g., a wireless node). A timing circuit may switch clock signals between two different modes (e.g., high power and low power) while preserving timing precision. In a high-power mode, the timing circuit may provide a high frequency clock signal, and in a lower-power mode, it may provide a low frequency clock signal. Moreover, the switching between the different clock signals may be synchronized to select edges of the low frequency clock signal.

Abstract: A system for providing synchronous access to hardware resources includes a first network interface element to receive a network time signal from a data communication network and a memory to store sequence of one or more instructions selected from an instruction set of the first processing circuit. The sequence of one or more instructions include a first instruction that is configured to synchronize execution of a second instruction of the sequence of one or more instructions with the network time signal. The system further includes a first processing circuit to use the first instruction and a timing parameter associated with a second instruction to execute the second instruction in synchrony with the network time signal.
