Discussion of Microkernel and Monolithic Kernel Approaches

The paper discusses monolithic approach against microkernel approach both used in operating systems. The paper presents the most critical features of operating systems concerning system architecture, communication model, and priority in processes, memory management and handling of any arrived exceptions as well as interrupts. The interrupt is a crucial factor for real time operating systems (RTOS). It is supposed the interrupts to be handled in real time for predictable time. The paper points out the benefits of each discussed approach and its weak points. At the end a conclusion for each appropriate operating system deployment is made, based on facts and results, and also on prediction for functionality. The paper discusses also the embedded systems as one of the most fast developing systems and mostly suitable platform for any RTOS installation or any other operating systems (OS) functionality.
