SoC chip structure applied to steering engine control system

Abstract

The invention discloses an SoC chip structure applied to a steering engine control system. The SoC chip structure comprises a bus, a bridge, a CPU subsystem, a memory subsystem, a control output subsystem, an input sampling subsystem, a peripheral subsystem and a clock reset subsystem, and is characterized in that the bus comprises a high-speed bus and a low-speed bus, and the high-speed bus is connected with the low-speed bus through a bridge. According to the SoC chip structure, signals are output to the steering engine braking subsystem through the DAC and the PWM, and then signal conversion in the steering engine control system is realized through the ADC integrated in the chip, and the 32-bit RISC CPU analyzes and processes the data, so loop control of the steering engine control system is realized. According to the SoC chip structure, problems of high system development complexity and large size of a discrete device integration implementation scheme of the steering engine controlsystem are effectively solved.

Description

technical field [0001] The invention relates to the field of precision control SoC chip structure, and more specifically, relates to a SoC chip structure applied to a steering gear control system. Background technique [0002] The servo control system consists of DAC and PWM output, ADC signal acquisition and CPU processing. At present, the control system of the steering gear is mainly implemented by discrete devices such as single-chip microcomputer + PWM generator / ADC / DAC. For example, when domestic and foreign companies and related units are developing and designing steering gear control systems, they adopt a low-power single-chip microcomputer + discrete device integration scheme such as ADC and DAC chips. This is mainly because there is no dedicated control SoC chip developed for the application requirements of the steering gear control system, so the secondary integration scheme of discrete devices based on low-power single-chip microcomputers can only be used, which ...
