Abstract

The invention relates to the technical field of electronic communication, and discloses a method for AMBA bus function safety protection, which comprises the following steps: judging the legality of a slave device address under the condition that a master device initiates a data transmission request; under the condition that the slave device address is legal, authentication is carried out; under the condition that the equipment authentication is passed, transmitting related information, and verifying the transmitted information; and sending alarm information under the condition that an error is found through verification. The legality of the slave device address is judged, and the device is authenticated. And transmitting related information and verifying the information under the condition that the authentication is passed. In the process, verification protection of transmission data can be effectively achieved, wrong slave device protection is supported, permission access is supported, and therefore the blank of function safety design of the AMBA bus is effectively filled up. The invention further discloses a device for AMBA bus function safety protection, electronic equipment and a storage medium.

Description

technical field [0001] The present application relates to the technical field of automotive electronics, for example, to a method, device, electronic device, and storage medium for safety protection of AMBA (Advanced Microcontroller Bus Architecture) bus functions. Background technique [0002] Functional safety design is a means to improve product functional safety. With the rapid development of automotive electronics, the complexity of automotive electrical and electronic systems is increasing. How to ensure the safety and reliability of automotive electrical and electronic systems has become a problem faced by all vehicle manufacturers and suppliers. At present, the international research on functional safety design of products is based on the ISO (International Standardization Organization, International Organization for Standardization) 26262 standard, which is derived from IEC61508 and is applicable to the field of automotive electronics. The ISO26262 standard clearly...
