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.
A microkernel allows the implementation of the remaining part of the operating system as a normal application program written in a high-level language, and the use of different operating systems on top of the same unchanged kernel. It is also possible to dynamically switch among operating systems and to have more than one active simultaneously.
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).
MkLinux (for Microkernel Linux) is an open-source software computer operating system begun by the Open Software Foundation Research Institute [1] and Apple Computer [2] in February 1996, to port Linux to the PowerPC platform, and Macintosh computers. The name refers to the Linux kernel being adapted to run as a server hosted on the Mach ...

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".
GNU Hurd is a collection of microkernel servers written as part of GNU, for the GNU Mach microkernel. It has been under development since 1990 by the GNU Project of the Free Software Foundation, designed as a replacement for the Unix kernel, [4] and released as free software under the GNU General Public License.
