Multi-core and VMM Based Non-interference Test Method of Embedded System Software

摘要

Traditional test methods of embedded system software impose on the object system and the result of the test are not accurate enough as expected. Non-Interference Test Method (NITM) can solve the problem. Not same with the traditional test methods, NITM is completely non-interference to the object software, does not add any instructions executed only within the test round into the object program. By analyzing the basic characteristics of NITM, an application model of NITM is set up. In many case of embedded system software test, the data need to process is very large amount so that we can not test all kinds of target real-timely. How can we achieve that in an embedded system since we have met such requirements in real engineering project? We brought a multi-core and Xen based NITM model to upgrade NITM so as to resolve the problem.
