Date Acquisition of Embedded Software Testing

Data acquisition is one of the key techniques of embedded software testing. Its accuracy, real-time and reliability have a decisive impact on the quality of testing. Some of testing needs a custom design of data acquisition methods based on software features and testing requirements. Focused on instrumentation as a invasive software testing technique, the hardware acquisition, hardware transceiver, pure software implementation process of instrumentation are researched.Boundary scanning technology and virtual simulation technology which are called as non-invasive data acquisition methods are analyzed. The idea of integrated application platform of development and testing for embedded system, and full life cycle embedded software development, testing and management ideas are introduced, which points out new directions for embedded software testing.
