Rapid Software Reuse on any Operating System with Performance Optimization

OS Changer® is a C/C++ source-level virtualization technology that allows you to easily re-use your software developed for VxWorks®, pSOS®, Linux/POSIX, Windows®, Nucleus®, ThreadX®, μITRON, µC/OS™, FreeRTOS™ and RTLinux on another OS, while providing real-time performance. It eliminates the manual porting effort, saves money and shortens the time to market. The appropriate OS Changer Interface connects to your existing application that was developed on your current OS while the OS Abstractor® Target Specific Module (specific to your target OS) provides the connection to the OS you are moving to.

Frequently Asked Questions about OS Changer

Q: What value does OS Changer provide?
A: The OS Changer family of products gives users the freedom to switch operating systems while leveraging on 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. More information can be found here: http://www.mapusoft.com/os-changer-porting-kit

Q: Why not do a port myself?
A: It’s not easy to make existing software adapt to a new OS without incurring high cost and time to market. It’s an error prone, tedious and time-consuming task and it requires expensive and skillful resources that take away the focus on building your product.

Q: Why don’t I use my new OS vendor’s porting kit?
A: OS vendor’s solutions are restricted and tied to a specific OS. Comparatively, MapuSoft provides solutions that port to many different operating systems. OS vendor’s solutions are usually unsupported because they are more focused on building and maintaining their operating system; many of them are partners with MapuSoft and would rather rely on us to help you move your code to their OS.

Q: Why don’t I throw out my code and start anew?
A: There are many reasons to leverage your legacy code. Here are a few:

  • Leverage existing software and knowledge base when migrating to next generation platforms
  • Achieve your time to market goals
  • Don’t throw away your software investment

Q: Why would I need to change my OS?
A: There are many reasons you would need to change your operating system. Here are a few:

  • OS becomes unsupported or obsolete
  • New chip architecture has different OS availability
  • Customer demands for different OS
  • Need to adhere to industry standards
  • Change in your technical requirements
  • Change in your commercial business model
  • Need to use a better development environment
  • Need to move to a widely used OS and target platform that offers a wide range of driver, protocol and middleware support

Q: Which operating systems can I port my legacy code from?
A: OS Changer supports porting from VxWorks, pSOS, Nucleus, and Windows to different operating systems. Additional OS component support is also available:

  • VxWorks ANSI File and VxWorks BSD Network API compliance for other target RTOS’s
  • pSOS Classic OS Changer allows developers to re-use their pSOS 4.1 rev. 3/10/1986 code on different operating systems
  • Nucleus NET OS Changer allows developers to re-use their Nucleus NET code on a Linux netstack
