Abstract

The invention discloses a data verification acceleration method and device, computer equipment and a storage medium. The method comprises the steps of obtaining to-be-verified data; performing segmentation processing on the to-be-verified data based on the standard data size of the preset data block, and determining a plurality of verification blocks, the verification data size of the verification blocks being equal to the standard data size of the preset data block; obtaining a request message sent by an upper computer, and judging whether the request message is a verification request or not; if the request message is a verification request, executing an asynchronous verification processing program to verify the multiple verification blocks, wherein the asynchronous verification processing program comprises an interrupt processing program and an asynchronous calculation program, the interrupt processing program is used for sending a verification waiting response to the upper computer, and the asynchronous calculation program is used for calculating the verification blocks; and sending a verification response to the upper computer after the calculation is finished. According to the invention, the processing speed of data verification is improved by expanding the data size of the verification block for each verification processing and adopting an asynchronous calculation method to perform data verification.

Description

technical field [0001] The invention relates to the technical field of electronic control, in particular to a data verification acceleration method, device, computer equipment and storage medium. Background technique [0002] When using the upper computer to monitor the vehicle electronic control unit, it is necessary to initialize the electronic control unit. During the initialization connection process, it is necessary to verify the data area where the application program of the electronic control unit is located. Due to the large amount of data in the data area Larger, therefore, the data needs to be segmented and verified. [0003] In the prior art, when the software and the host computer perform data verification, the data verification is performed in the interrupt processing program, and the data size of the data block for each verification is generally set to 1K to ensure the interrupt execution efficiency. With the improvement of software functions, the data content...
