Abstract

The invention provides a safe electrification method and system for a system-on-chip, a chip and electronic equipment. The safe electrification method specifically comprises the following steps: triggering a read-only memory in a microcontroller to configure a chip register under the condition that a one-time programmable memory cannot configure the chip register; under the condition that the microcontroller cannot be normally started, triggering the electrically erasable read-only memory to configure a chip register; and under the condition that the electrically erasable read-only memory cannot configure the chip register, triggering the system-on-chip to execute reset starting and enter a normal working state. According to the technical scheme, the microcontroller, the one-time programmable memory and the electrically erasable read-only memory are used at the same time, the power-on process of the system-on-chip, especially the register configuration link in the power-on process, is controlled, and then the safety and reliability of the whole power-on process of the system-on-chip are guaranteed.

Description

technical field [0001] The invention relates to the technical field of chip electrification configuration, and in particular discloses a safe electrification method, system, chip, electronic equipment and readable storage medium. Background technique [0002] With the rapid development of integrated circuit technology, the circuit functions in the chip are becoming more and more complex, and more and more functions are integrated in a single chip. Develop towards the systematic direction of multifunctional IP integration. Among them, a system-on-chip (System on Chip, SOC) chip has become a main solution to replace traditional integrated circuits, and has become an inevitable trend in the development of current microelectronic chip technology. [0003] A system-on-a-chip usually integrates processors, registers, memories, and various interface control modules, and various functional modules are combined according to a certain connection relationship to form a complex system-...
