Nanokernel architecture
WitrynaEn informática , un microkernel (a menudo abreviado como μ-kernel ) es la cantidad casi mínima de software que puede proporcionar los mecanismos necesarios para implementar un sistema operativo (SO). Estos mecanismos incluyen la gestión del espacio de direcciones de bajo nivel , la gestión de subprocesos y la comunicación … WitrynaNano-kernelis a very small amount of kernel code executing in hardware. Abstraction layer is the lowest layer of the kernel. Nano kernel provides all services virtually including most basic like interrupt controller or time to device drivers and requirement of memory even smaller than a microkernel.
