RTX Kernel Library can be used with devices based on:
- ARM7 and ARM9
- Cortex-M0/M1, Cortex-M3, Cortex-M4, and Cortex-R4
Cortex-M processor-based devices have extended RTOS features, which allows more robust and fail-proof RTX kernel implementation. The main concept differences are:
- ARM7 and ARM9 versions use the system task manager to control task switches of all user tasks. Tasks are executed in System Mode.
- Cortex-M versions use system calls that are all executed as SVC System Supervisor Calls.
In addition, refer to :
- Technical Data - lists hardware requirements, RAM and code space, number of possible tasks, ...
- Timing Specifications - lists timing measurements (cycles) for various RTX functions.
