The OS Changer family of products are COTS porting tools that give users the freedom to change operating systems while reusing their existing embedded code and knowledge base to protect their software investment and avoid costly porting issues. OS Changer also allows developers to write code using a familiar application programming interface (API) and run the application on a wide variety of supported target OS platforms. Solutions are available for porting from VxWorks, pSOS and Nucleus to many different real time (RTOS) and non-realtime operating systems.
