• ARM7 and ARM9
• CORTEX-M0/M1, CORTEX-M3, CORTEX-M4, and CORTEX-R4

The CORTEX-M processor has enhanced RTOS features. These features make the kernel porting process of rtx more automated and less error-efficient.

The main differences between the above two types of processors are:

• The ARM7 and ARM9 processors use the system Task Process Manager to control the switchover of all user task processes. The task process runs in system Mode.
• CORTEX-M processors, these system calls rely on the SVC system Supervisor Calls

In addition, there are many other differences between these two types of processors, and the RTX performance is not the same.
