Abstract

The invention provides an SoC chip structure applied to a chip atomic clock control system. The structure comprises a CPU subsystem, a memory subsystem, an input sampling subsystem, a control output subsystem, a time difference measurement subsystem, a common external subsystem and a clock reset subsystem. The CPU subsystem is connected with the memorizer subsystem through an AHB, the AHB is connected with an APB through a bridge, and the APB is connected with the input sampling subsystem, the control output subsystem, the time difference measurement subsystem, the common external subsystem and the clock reset subsystem separately. According to the SoC chip structure, the problems are solved that a discrete device integration implementation scheme of the chip atomic clock control system ishigh in system development complexity, large in size and not beneficial to miniaturization of a chip atomic clock; an SoC chip can not only meet the application requirement of the chip atomic clock control system and but also meet the application equipment of the field similar to precision control.

Description

technical field [0001] The invention belongs to the field of precision measurement and control servo control, and in particular relates to a SoC (System-on-a-Chip, system integrated chip) chip structure applied to a chip atomic clock control system. Background technique [0002] The chip atomic clock control system includes VCSEL (Vertical Cavity Surface Emitting Laser) temperature loop control in the physical system, absorbing bubble temperature loop control in the physical system, laser frequency loop control, and microwave frequency-locked loop Control and C-field control of the physical system, a total of four closed-loop and one open-loop control. To realize the control system of the chip atomic clock, the ADC needs to collect the signal to be controlled (such as the temperature signal and the light detection signal), and then the processor analyzes and processes the converted data collected by the ADC, and finally outputs it through the DAC feedback. According to the ...
