What Is an RTOS?

A Real-Time Operating System (RTOS) is a software platform for real-time computing applications that process events and data with well-defined time constraints. Unlike general-purpose operating systems (GPOS), an RTOS must schedule processing and data sharing between applications on limited hardware resources. Typically, these applications respond to inputs within microseconds and run on small embedded devices with less than 1 MB of memory. In this section, you’ll learn more about what an RTOS is as well as RTOS types and architectures.

RTOS in Embedded Systems

An embedded RTOS is the underlying software mechanism by which embedded applications run, interoperate with each other, and communicate with the outside world. In this section, you’ll learn about popular RTOSes that embedded software developers use and the embedded hardware platforms they run on.

What to Expect in an RTOS

An RTOS uses various mechanisms to manage tasks, events, and memory to ensure time constraints are met in embedded systems. In this section, you’ll learn about RTOS features to consider when building your embedded applications, such as determinism, spatial and temporal separation, scheduling, memory management, and interprocess communications.

RTOS Best Practices

When writing applications on an RTOS, there are additional considerations. Here, you’ll learn RTOS development best practices, such as POSIX compliance, security, and functional safety certification.

How to Choose the Best Embedded RTOS

Your choice of RTOS affects embedded system performance, development time, regulatory compliance, and total cost. The main selection criteria for an RTOS are usually the overhead it imposes on the processor and response time of RTOS functions

How Can PX5 RTOS Help You?

PX5 RTOS is one of the smallest, highest performance RTOSes ever developed. Ideal for resource-constrained devices, PX5 RTOS delivers sub-microsecond context switching and API calls, and it requires less than 1 KB of flash memory to run. Designed as a native implementation of the POSIX pthreads API standard, PX5 RTOS enables code portability with embedded Linux and other POSIX RTOSes.
