VLOG: A Beginner’s Guide to the Embedded RTOS Programming and Kernel Porting
Fast & Real-time response, Efficient processing of the concurrent tasks, increased support for connectivity: These are some of the critical requirements that are demanded by new-age embedded system applications.
This is especially true for event-driven software applications such as Vehicle Telematics, Advanced Driver Assistance System, Body Control Module & Solar Tracking Platforms.
In such applications, the consequences of any delay in processing data and responding to an urgent event, can be detrimental!
What is an RTOS (Real Time Operating System) and Why it is Important?
Such time-critical embedded applications necessitate the support of an OS architecture that can:
- Support the applications to respond to a sudden event, within a defined time-stamp
- Execute multiple tasks as per pre-assigned priority
- Handle seamless sharing of computing resources among multiple tasks
The only embedded Operating System architecture that can guarantee all these functions is Embedded RTOS( Real Time Operating System).
Wikipedia defines a real-time operating system (RTOS) as “an operating system (OS) intended to serve real-time applications that process data as it comes in, typically without buffer delays.”
While the General Purpose OS (GPOS) such as Linux and Android are widely used for various development embedded applications, they are not designed to cater to the requirements of time-bound and event-driven applications.
On the other hand, as Wikipedia states, a real-time operating system (RTOS) is valued more for how quickly or how predictably it can respond than for the amount of work it can perform in a given period of time.
We also have a tech blog detailing “What Makes RTOS an Ideal Choice for the Next Generation Embedded Applications?”. Do have a look at it.
So, how does an RTOS add value to embedded system development eco-system? Why is an embedded RTOS preferred over general purpose OS when it comes to time-critical embedded applications?
