clarification Zephyr kernel type

Khalid Talash <khalid.talash@...>


I am currently writing a paper comparing different RTOSs. I want to compare the kernel architecture types of the different RTOSs but Zephyrs kernel confuses me a little bit. I get from literature and wikipedia that basically kernel types are monolithic or microkernel. From your visualization of system architecture on your security overview page I would guess Zephyr uses microkernel type because functionalities like file systems and IPC are seperate from Kernel. But your documentation also says Zephyr uses unified kernel which on the other hand sounds like monolithic to me.
Could you please which classification of kernel type (monolithic or microkernel) fits Zephyr? This would help me so much.

Thanks in advance.
