International Classification:

G01R 31/28

US Classification:

714727, 714731

Abstract:

A chain of boundary scan registers is configured to use a two-phase clock signal to avoid data timing race conditions. The two-phase clock signal is generated according to a two-phase clock generator, which includes two self-timed clock pulse generators for each boundary scan register. The two-phase clock generator locally generates a self-timed clock pulse at the rising edge of a clock signal, which triggers a first stage of the boundary scan register. The two-phase clock generator also generates a self-timed clock pulse at the falling edge of the input clock signal, which triggers a second stage of the boundary scan register. The two-phase clock controlled boundary scan register includes two latches, each latch is triggered by one of the self-timed clock pulse generated locally from the rising and falling edge of the input clock signal.

Abstract:

Methods, systems and apparatuses pertaining to pertaining to precise localization and vehicle-to-everything (V2X) communication for autonomous driving vehicles are described. A processor associated with a vehicle wirelessly obtains a respective location of each of one or more traffic control devices. Each of the one or more traffic control devices is installed near or next to a road, an intersection or an area open to vehicular traffic. The processor then determines a location of the vehicle based at least in part on the respective location of each of one or more traffic control devices.
