Embedded software simulation testing environment based on virtual machine

In order to enhance the quality and reliability of embedded software, an embedded software simulation testing environment based on virtual machine was proposed. The virtual machine technology was introduced into the simulation testing field of embedded software, and the constitution principle of embedded software simulation testing environment was introduced. In addition, the virtual machine technology was analyzed, and an embedded software simulation testing virtual machine (ESSTVM) based on an extended program-transplantation virtual machine model was proposed. And the design scheme for the memory management and instruction system was presented. The ESSTVM was applied to the design of avionics embedded software simulation testing environment (AESSTE), and the system structure of the testing environment was studied. Moreover, the design and realization of both testing development and testing execution systems were elaborated, and the transportability of AESSTE was analyzed. The analysis results show that the proposed method can effectively improve the universality, transportability and maintainability of embedded software testing environment.
