Presentation on theme quotREAL-TIME OPERATING SYSTEMSquot Presentation transcript RTOS is a pre-emptive multitasking operating system intended for real-time applications Predictable OS timing behavior Able to determine task's completion time A system of priority inheritance has to exist Guarantees task completion at a set deadline.

Correctness of output depends on timing as well as result Hard vs. soft real-time Are Windows and Linux real-time? In a Hard RTOS Thread priorities can be set by the client Threads always run according to priority Kernel must be preemptible or bounded Interrupts must be bounded No virtual memory In a Soft RTOS

facilities in the real-time kernel until the real-time executive replicates facilities of Linux. 32 Adapt Linux . The original Linux kernel is replaced with a compatible kernel with hard real-time performance characteristics. The kernel is only a small part of a whole operating system. If just the Linux kernel is

Real-time operating systems RTOS are used in applications that must process events within strict time constraints. An RTOS guarantees that critical tasks are completed on time through priority-based scheduling.

Normal program execution resumes Let the operating system handle scheduling, and let the programmer handle function Execution time Period Deadline Time Initiation INU 1kHz GPS 20 Hz Air data 1 kHz Joystick 500 Hz Pitch control 500 Hz Lateral Control 250 Hz Throttle Control 250 Hz Aileron 1 1 kHz Aileron 2 1 kHz Elevator 1 kHz Rudder 1 kHz gyros

Software that manages the time and resources of a CPU Application is split into multiple tasks The RTOS s job is to run the most important task that is ready-to-run On a single CPU, only one task executes at any given time What Is An RTOS? - Multitasking 22 RTOS Code Task CodeData Stack Task CodeData Stack Task CodeData Stack Task
