A bit flipping effect-oriented SoC chip-based reconfigurable flexible control method

Abstract

The invention discloses a bit flipping effect-oriented SoC chip-based reconfigurable flexible control method, which is a reconfigurable and multi-configured embedded control system and can correctly correct bit flipping faults occurring in a microprocessor and a memory unit. Comprising the following steps: aiming at the SoC chip, setting an ARM reconstruction module in a boot loader of a boot loader in an eNVM area in the SoC chip, wherein the ARM reconstruction module is used for reconstructing an ARM controller. In a main control program of the ARM controller, an FPGA reconstruction module is arranged, and the FPGA reconstruction module is used for reconstructing the FPGA controller. The system is based on an SoC chip, a traditional embedded control system design architecture based on ARM + FPGA is improved, an ARM controller can reconstruct an FPGA controller on line through a reconfiguration module, and real-time circuit dynamic reconstruction is achieved; meanwhile, a boot loader is designed at the initial address of the ARM controller, and the program can guide the ARM controller to complete self-reconstruction, so that online upgrading is realized.

Description

technical field [0001] The invention relates to the technical field of the embedded field, in particular to a reconfigurable and flexible control method based on a SoC chip oriented to the bit flip effect. Background technique [0002] In many fields such as communication, network, multimedia, aerospace, etc., the embedded control system based on ARM+FPGA has been applied more and more because of its superior performance and modular control function. However, the existing embedded control system cannot be reconfigured online, which makes it inconvenient to recall the physical system formed in some application fields when the requirements change, and it needs to be disassembled to upgrade (such as external Automatic operation of equipment, inconvenient access to the equipment site, aerospace field, etc.), is very inconvenient, so it is necessary to remotely realize the reset of the system. Aiming at the existing embedded control system, especially the embedded system based o...
