WINDOWS EMBEDDED COMPACT 7 AND REAL TIME
Modern high-end embedded operating systems such as Windows Embedded Compact 7 offer a comprehensive set of services, covering almost the same functionalities as a general purpose operating system such as Windows 7:
- Multiprocess and multithreaded execution
- Virtual memory and page pooling
- Software timers and watchdogs
- Hardware abstraction through drivers
- Persistence with mountable file systems
- Standard communication protocols
- Component framework
- Integrated user interface services
- Multimedia framework
- Internet interface and browser
- Object-oriented framework
The first three services in this list offer a time deterministic behavior in Compact 7; other services such as memory allocation, file system primitives, or graphical user interface do not offer time-bounded behavior. Using Compact 7 as a foundation, you can combine several operating system services and keep the deterministic behavior of targeted modules exclusively based on time deterministic services (that is, threading, hardware drivers, and timers). During the architecture design stage, the separation between deterministic and nondeterministic modules will be based on thread priorities as they strictly guarantee the order of execution. Nondeterministic modules use low-priority levels and can even run in a Time Sharing scheme as Compact 7 offers on-demand quantum-based scheduling for threads at the same priority level. Deterministic modules use high-priority levels and must be carefully ...
