Embedded Software Test Platform Technology Research

As the embedded system becomes more and more widely applied, people's expectation and requirement on its quality rise accordingly and its testing techniques,an effective way to secure its quality becomes more and more concerned.Besides,the assembly language of this system,efficiently and frequently used as it is,does not confirm to the general norms.This brings great difficulty to the measuring and testing of the assembly-language software.As a result,there lacks an effective testing tool for embedded systems,especially a testing tool particularly designed for the analysis and testing of assembly-language software.The current practice in china is to test the systems by hand,which not only is ineffective but gives rise to serious potential leaks and other problems.This subject research will offer an unitized software integral test platform, which has good real-time responding ability, support most of the standard I/O interface, provides visible developing tools for emulating equipment with peripheral device running by tested software, supports many types of software test, and offers perfect test manage function.This subject research will improve the versatility of the testing platform, improve the resource utilization, and change exploit mode for all the software special test platform, at the same time, it can also reduce the development cost and cycle for software test system; the integral test platform processes with perfect test manage functions, which has high automatic level, so as to improve the test radio, and secure the software quality.The achievement of the research can be used not only in all embedded software test, but also for civil use; meanwhile, it can be provided for other civil specialized testing and assessing units, and all the civil embedded system researcher. So, this research is significance.
