What is an Real Time Operating System (RTOS): Types of RTOS

WebA Real-Time Operating System (RTOS) comprises of two components, viz., “Real-Time” and “Operating System”. An Operating system (OS) is nothing but a collection of system calls or functions which provides an interface between hardware and application programs. It manages the hardware resources of a computer and hosting applications that ... Webo Puts an RTOS kernel between the hardware and the OS. o Hard tasks run in the RTOS kernel, the OS runs when CPU is available. o Native applications can run without any changes. o Hard tasks get real -time properties. o See RTLinuxPro Problems: y A single failing hard task can kill the whole system. y The RTOS kernel requires its own IO drivers.
