Design and Implementation of Software Bus Based on Object Model Operating System

Abstract

At present, the commercial operating system VxWorks is the first choice of leading international intelligent equipment manufacturers. They implement their own equipment controller based on VxWorks. However, VxWorks is not specifically designed for the control field, so there are many deficiencies in the control field, such as: using a dynamic model, dynamically calling various resources at runtime, making the system less predictable and real-time. Aiming at the typical application scenarios of the object operating system, this paper gives the overall software architecture of the object bus. The designed object bus provides a transparent mechanism for communication between components. In view of the highly dynamic adjustment of the objects in the object bus, this article has designed a corresponding set of migration mechanisms for the object bus to solve the various negative effects of cache invalidation after dynamic adjustment. In the last part of the article, the functional verification of the implemented object bus is carried out, and the analysis and summary are carried out.
