Abstract: Embodiments of the present invention provide a carrier synchronization method, circuit, and system. The method includes performing n times frequency multiplication on a received signal; performing narrowband filtering at least twice and rectangular wave shaping at least twice on the signal obtained after the n times frequency multiplication; and performing n times frequency division on the signal obtained after the filtering and shaping, to restore a carrier signal. The variable n is a positive integer greater than or equal to 4.

Abstract: The present invention relates to the field of information communication and control, and discloses a method and an apparatus for adjusting transmit power and used to resolve a problem of interference between paths in a multipath system. The method provided by the present invention specifically includes: determining a path with worst signal quality according to signal quality information of each path; then, increasing transmit power of the path, or, decreasing transmit power of at least one path that produces strongest interference to the path with the worst signal quality; and finally, using a manner of cyclically adjusting signal transmit power to enable interference between the paths to meet a requirement of not affecting communications quality, thereby resolving a problem of interference between paths in a multipath system. Embodiments of the present invention are mainly used in a data transmission process in a multipath system.

Abstract: Method and systems for executing a non-maskable interrupt are provided. In one aspect, a method for executing a non-maskable interrupt includes: obtaining an interrupt request in a non-secure mode, and interrupting an operation of an operating system (OS); saving, in a secure mode, a status of the OS when the operation of the OS is interrupted; executing, in the non-secure mode, a procedure defined for the interrupt request; resume, in the secure mode, the status of the OS; and after resuming the status of the OS, continue executing the operation of the OS in the non-secure mode.

Abstract: The present invention discloses a method and an apparatus for executing a non-maskable interrupt. The method includes: obtaining a secure interrupt request in a non-secure mode, and interrupting an operation of an operating system OS, where the secure interrupt request cannot be masked; entering a secure mode by using the secure interrupt request, and saving, in the secure mode, an interrupt context of an OS status when the operation of the OS is interrupted; returning to the non-secure mode to execute user-defined processing; after the user-defined processing is completed, entering the secure mode again, and resuming the OS status in the secure mode according to the interrupt context; and returning to the non-secure mode again, and continuing to execute an operation of the OS. The method and the apparatus for executing a non-maskable interrupt in embodiments of the present invention can easily implement an NMI mechanism without depending on hardware.
