Data processing method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a data processing method and device, electronic equipment and a storage medium, and the method comprises the steps: receiving a data access request sent by a target central controller in at least one central controller, obtaining an access parameter of the target central controller from the data access request, the data access request carries a target data access address; acquiring a preset data access address according to the access parameter of the target central controller; and judging whether the target data access address is consistent with a preset data access address or not, and processing the data in the memory according to the target data access address when determining that the target data access address is consistent with the preset data access address. By using the scheme, the memory can be prevented from processing data of wrong addresses in the running process of the data processing equipment, so that the problem that memory data access address intervals interfere with one another is solved. And a relatively large storage space does not need to be occupied, and the data processing efficiency is improved by comparing the target data access address with the preset data access address.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technologies, and in particular, to a data processing method, apparatus, electronic device, and storage medium. Background technique [0002] With the widespread use of vehicle electronic control units, the control of most automotive components is inseparable from software operation. The software operation involves a large amount of data running in a central controller (central processing unit, CPU for short), and during the running process, the data will be continuously written and read in the internal memory or the external memory. Although the data storage address of the fixed memory is specified in the central controller, there is still a problem that the data is written to the wrong memory address due to the failure of the data bus during operation, resulting in an error in the input data of the subsequent operation. [0003] Generally, the following solutions are used to avoid ...

[0004] In the implementation process using the above solution, because the same data needs to be stored in two different addresses, the occupied memory space is doubled, and there is a waste of storage resources, and in the process of real-time operation, each time the data is read Real-time verification of data is required, resulting in reduced data processing efficiency
