| Abstract: | A general BIT software architecture is designed and developed, which can be applied to airborne embedded computers. The BIT software is designed to be divided into hardware driver layer, test algorithm layer, test configuration and control layer, application interface layer, and so on. In this way, the portability of bit software in different hardware and OS environments can be implemented to a great extent. The design also defines a method to realize hardware BIT detection before the OS is set up, which can effectively improve the failure detection rate of hardware resources such as memory, CPU, etc. |
