Hello,
I'm making a study about the real time OS based on linux. To do that I would to know if anybody can give me information about an RTOS on which one he worked or studied. Indeed to do my repport I want to answer for each OS at those questions:
- Supported Target CPU
- Supported Network
- Kernel ROM/RAM (min, max)
- Min RAM per process
- Min RAM per thread
- Min RAM per queue
- Number of priority level
- Thread switch latency (Typical, Max)
- Guaranteed Max Interrupt latency (typical, max)
- System Clock Resolution
- Multiprocess supported ?
- Multi-CPU supported ?
- Scheduling policy ?
If you have those information (for any CPU or architecture) please give me them (don't forget to specify the CPU when it's needed). I'm especially interresting by FreeRTOS, RTAI, RTLinux (free version), ...
Many thanks
