Abstract
An electronic eyewear device includes first and second systems on a chip (SoCs) having independent time bases that are synchronized by generating a common clock signal from a clock generator of the first SoC and simultaneously applying the common clock signal to a first counter of the first SoC and a second counter of the second SoC whereby the first counter and the second counter count clock edges of the common clock. The clock counts are shared through an interface between the first SoC and the second SoC and compared to each other. When the clock counts are different, a clock count of the first counter or the second counter is adjusted to cause the clock counts to match each other. The adjusted clock count is synchronized to the respective clocks of the first and second SoCs, thus synchronizing the first and second SoCs to each other.
