This is a list of real-time operating systems (RTOSs). This is an operating system in which the time taken to process an input stimulus is less than the time lapsed until the next input stimulus of the same type. Mostly Texas Instruments C2800, C5500, C6000 and OMAP DSP cores. Replaced by TI-RTOS, but available for download.

FreeRTOS+POSIX provides a POSIX threading API for FreeRTOS, enabling easier porting of existing POSIX-compliant code to FreeRTOS.

LynxOS-178 has the strongest alignment to the POSIX APIs (PSE 53/54 profiles supported) across all suppliers of real-time operating systems (RTOS), which simplifies the migration of …

The name PX5 is an abbreviation where P stands for POSIX threads, X stands for thread switching, and 5 represents fifth generation RTOS. Written in ANSI C, the PX5 RTOS is compatible with various embedded microcontroller unit (MCU) and …

May 9, 2024 · 在开发实时应用时，我们希望软件具备良好的跨平台和可移植，既能在实时linux也能在RTOS上工作，为实现这个目的，我们会选择使用POSIX API来设计实时应用，实现在不同的操作系统和平台上的可移植性。 这样只要有POSIX支持，应用程序从一个操作系统移植到另一个操作系统，无需对源代码进行较大的修改，可以减少很多重复工作（想象很美好）。 但是，实时应用除关注接口基本功能一致外，还关注接口的实时性（执行时间确定性），那不同的实时操作系 …

In this workshop we'll cover general RTOS topics. The SimpleLink™ software development kit (SDK) supports both TI-RTOS and FreeRTOS. It also supports POSIX APIs on top of either RTOS. We'll use POSIX APIs below as a concrete example of an RTOS but the concepts are applicable for both RTOS offerings. Here's what we'll learn:

RTEMS : one process/several threads, several API including POSIX. POSIX API for real-time systems : thread and fixed priority scheduling, semaphore/mutex and inheritance protocols, timer/clock and periodic thread releases.

FreeRTOS+POSIX implements a subset of the POSIX threading API. With FreeRTOS+POSIX, an existing POSIX threading compliant application can be ported to run on the FreeRTOS kernel, and therefor leverage all the Amazon FreeRTOS functionality.

The POSIX real-time extensions define real-time services such as real-time signals, real-time scheduling policies, task synchronization mechanisms, clocks, and timers.

The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. With FreeRTOS+POSIX, an existing POSIX compliant application can be easily ported to FreeRTOS ecosystem, and thus leveraging the entire AWS IoT service stack.
