Porting of an Embedded RTOS into a Userspace Process

Background

Embedded systems with real-time requirements employ specialized Real-Time Operating Systems (RTOS). These Operating Systems are very light-weight and highly configurable and can be covered completely to certify the real-time compliance. Generally, they are executed on a Microcontroller. On the other hand, current x86 Processors include multiple cores and huge computing power. Operating Systems for mainstream Computers are far too complex to be analysed completely. Only soft real-time capabilities can be proven by black box testing.

For an ongoing research project, an RTOS shall be executed within a Linux process. The Hardware Abstraction Layer of freely available RTOS is designed to ease the porting to new hardware. In a Linux Process, UNIX-Signals can replace Interrupts, Memory Management is done comfortably with malloc() and other hardware is handled with the according interfaces.
