SoC chip structure applied to gyroscope control system

Abstract

The invention discloses an SoC chip structure applied to a gyroscope control system. The SoC chip structure comprises buses, a bridge, a CPU subsystem, a memory subsystem, a control output subsystem, an input sampling subsystem, a peripheral subsystem and a clock reset subsystem; the buses comprise a high-speed bus and a low-speed bus; and the high-speed bus is connected with the low-speed bus through the bridge. According to the SoC chip structure applied to the gyroscope control system, signals are output to a gyroscope braking subsystem through a DAC and a synchronous output module, signal conversion in the gyroscope control system is achieved through an ADC integrated in the chip, data analysis and processing are conducted through a 32-bit RISC CPU, and therefore loop control and the like of the gyroscope control system are achieved; and the problems of high system development complexity and large size of a discrete device integration implementation scheme of the gyroscope control system are effectively solved.

Description

technical field [0001] The invention relates to a SoC chip structure in the field of precision control, and more specifically, relates to a SoC chip structure applied to a gyroscope control system. Background technique [0002] At present, the control system of the gyro is mainly realized by discrete devices such as FPGA+ / ADC / DAC. For example, when domestic and foreign companies and related units are developing and designing gyro control systems, they adopt the solution of integrating discrete devices such as FPGA+ADC / DAC chips, such as figure 1 shown. This is mainly because there is currently no dedicated control SoC chip developed for the application requirements of the gyro control system, so only the secondary integration of discrete devices can be used, which increases the complexity of the development of the gyro system, and the control realized by the integration of discrete devices The size of the system is large, making the miniaturization of the gyroscope a bottl...
