| The demand for3G data cards grows rapidly due to the growth of new dataservices. Since data card market changes continuously, it is of great significance toupdate data cards timely. Based on the development process of Qualcomm platformmobile terminal assistive tools, this paper studies the design and development of thedata card download tools of PC side.This paper first presents the basic knowledge and principles of download, as wellas the theory of flash memory and WCDMA basics. Then the functional requirementsand performance requirements of download tool are analyzed specifically, and thedesign is based on the overall architecture and download process of the tool. After that,multi-channel data card download tools three-tier architecture and download functionare realized under VS2008programming environment. Finally, the functional andperformance testing of download tool are conducted under the aid of Bus Hound,Beyond Compare and QPST, and analysis of the test results is also presented.Occasional download failure and NV item backup error in Windows Vista64system aresuccessfully removed through access to the relevant technical documents. |
