Target file checking method and apparatus

Abstract

An embodiment of the invention provides a target file checking method and apparatus. The method comprises the steps that: an upper computer downloads a target file; the upper computer performs checking for the target file to obtain a first checking result; the upper computer sends the target file to a lower computer; the lower computer is used for performing checking for the target file to obtain a second checking result; the upper computer receives the second checking result sent by the lower computer; the upper computer judges whether the first checking result is the same as the second checking result; if so, the upper computer judges that the target file is downloaded successfully; and if not, the upper computer judges that the target file is downloaded unsuccessfully. According to the embodiment of the invention, the target file checking method and apparatus are used for quickly checking the downloaded file, shortening the checking time, reducing calculation resources for file checking, and ensuring the correctness of the downloaded file.

Description

technical field [0001] The invention relates to the technical field of memory data processing, in particular to a method for verifying an object file and a device for verifying the object file. Background technique [0002] With the rapid development and wide application of various electronic devices and embedded systems, such as computers, personal digital assistants, mobile phones, digital cameras, etc., there is a great need for a device that can be programmed many times, has a large capacity, is fast to read and write, and can be erased. Convenient, simple, less peripheral devices, low-cost memory. [0003] In the process of downloading files in batches from the memory, in order to ensure the correctness of the downloaded files and the security of the downloaded files, it is usually necessary to verify the downloaded files. However, in the traditional verification method, the upper computer needs to download the file downloaded to the lower computer, and then download i...

Problems solved by technology

However, in the traditional verification method, the upper computer needs to download the file downloaded to the lower computer, and then download it again from the lower computer, so as to verify the correctness of the file downloaded by the lower computer. It is understandable that the traditional verification method requires It takes a long time to verify and the efficiency is low

But in reality, in order to obtain the greatest economic benefits, it is necessary to quickly verify the correctness of downloaded files, thereby saving time, improving efficiency, and reducing the computing resources required for verifying files. Obviously, traditional verification methods can no longer meet the existing demand
