In computer science, a microkernel (often abbreviated as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC).
F9 microkernel, [35] a BSD-licensed L4 implementation, is dedicated to ARM Cortex-M processors for deeply embedded devices with memory protection. The NOVA OS Virtualization Architecture [ 36 ] is a research project with focus on constructing a secure and efficient virtualization environment [ 37 ] [ 38 ] with a small trusted computing base.
μT-Kernel is an open source real-time operating system (RTOS) designed for 16-and 8-bit microcontrollers. "μ” in the name stands for "micro" and pronounced as such.It is not pronounced as "mu".
A microkernel is a minimal computer operating system kernel which, in its purest form, provides no operating system services at all, only the mechanisms needed to implement such services, such as low-level address space management, thread management, and inter-process communication (IPC).

By the mid-1990s, work on microkernel systems was largely stagnant, although the market had generally believed that all modern operating systems would be microkernel based by the 1990s. The primary remaining widespread uses of the Mach kernel are Apple's macOS and its sibling iOS, which run atop a heavily modified hybrid Open Software ...
The L4.sec system, which is a successor to the L4 microkernel family, is a capability-based system, and has been significantly influenced by the results of the EROS project. The influence is mutual, since the EROS work on high-performance invocation was motivated strongly by Jochen Liedtke's successes with the L4 microkernel family.
NuKernel is a microkernel that was developed at Apple Computer during the early 1990s. It was the basis for the Copland operating system.It was written from scratch and designed using concepts from the Mach 3.0 microkernel, with extensive additions for soft real-time scheduling to improve multimedia performance.
