Design And Implementation Of Data Testing Equipment Based On Embedded Platform

Using hardware to complete common data processing functions can reduce the cost of the memory and processor burden of the host, improve performance and security. With so many data processing equipment of different functions and fields developed, how to test them has become a problem. A common solution is to design a test equipment for a specific set of hardware devices. Highly customizable test equipment can perform the functions required for the test and can be applied to the entire range of products.In this paper, combined with some data processing equipment, a data testing equipment based on embedded platform is designed and implemented. It connects with the data processing equipment through the cable, communicates with the Windows client through the network,completes the data processing equipment control and the automated test.Test equipment bases on custom embedded platform. This paper complete the driver and the business logic applications on the basis of the platform. The drivers control the platform hardware effectively, and play the advantages of customization. The application achieve the test business logic. The whole test system is based on the traditional C/S architecture and divided into two parts, client and test equipment. The client provides the tester with a friendly interface, meanwhile the test equipment controls and tests the data processing equipment comprehensively. Test equipment accepts the client connection and test request as a server, sends the received data to the data processing equipment for encoding or decoding and returns the processed data to the client for comparison and display. Testers can locate the problem by viewing the test report. Testing the data processing equipment through this test equipment can greatly save test time and shorten the development cycle.
