PX5 has been set up by Bill Lamie, the former chief technology officer of Express Logic and architect of the Nucleus and ThreadX (Azure RTOS) real-time operating systems, and is an advanced, fifth generation RTOS designed for the most demanding embedded applications.
The PX5 RTOS features a native implementation of the industry standard POSIX pThreads API as well as best-of-class size, performance, safety, and security. In addition to the native POSIX pThread support with semaphores and message queues, the PX5 RTOS has been designed to offer real-time extensions such as event flags, fast queues, tick timers, and memory management.
PX5 enables a wide range of software stacks, both open source and commercial, to run on real-time embedded IoT platforms. All of this results in reduced time-to-market, improved firmware quality, and portability across platforms that help enhance device maker’s firmware development investment.
PX5 will integrate the Percepio Tracealyzer trace recorder, and Percepio will support the new PX5 RTOS with a commercially available version.
“PX5 RTOS is purpose built to deliver benefits across all IoT sectors including commercial and safety critical applications,” explained Bill Lamie, President, PX5. “It’s hard to correct an issue if you can’t see it. With Tracealyzer, developers can see exactly what is taking place before a system crash. Developers can also leverage this visualisation to better understand the firmware, which makes it easier to enhance and optimise its operation.”
“Being part of the launch of PX5 is exciting for Percepio,” added Johan Kraft, founder and CTO of Percepio. “pThreads is a valuable tool to embedded real-time engineers and combined with the other features in PX5 will supercharge the ability of Tracealyzer to monitor the performance of software running on all kinds of embedded systems across the IoT.”
The trace recorder in Tracealyzer 4.6 is easy to port to platforms such as PX5 to provide efficient monitoring of deployed IoT systems and tracing of multi-core systems. It allows developers to capture long software traces, spanning hours or even days, for example for burn-in testing or profiling, or when looking for rare errors.
A trace snapshot feature also works with DevAlert, Percepio’s cloud service for monitoring deployed IoT devices. DevAlert customers can see their device issues in the field and download traces of the issues into Tracealyzer for easier debugging.
