Express Logic develops, markets and supports the ThreadX® real-time operating system (RTOS), NetXTCP/IP networking stack, USBX USB stack, FileX® embedded file system, and PEGX GUI toolkit for embedded applications.
ThreadX is a royalty-free, full source code, small-footprint, low-overhead RTOS that is extremely easy to learn and use. ThreadX is one of the most widely deployed RTOS products in the world, with over 1.25 billion products based on ThreadX.
Definition: Whether you are designing a telecom switch, a piece of medical equipment, or one of the many complex systems aboard an aircraft, certain critical parts of the application must be able to operate under all conditions.
Indeed, given the steadily increasing speed of processors and the economically-driven desire to run multiple applications, at varying levels of criticality, on the same processor, the risks continue to grow.
Consider a blood gas analyzer used in an intensive care unit.
The analyzer may serve two distinct purposes.
First, it monitors the level of oxygen and other gasses in the patient's bloodstream, in real time.
If any monitored gas reaches a dangerously low or high level, the analyzer should produce an audible alarm or take some more direct, interventionary, action.
But the device may have a second use, offering a historical display of gas levels for 'offline' analysis.
In such a system, data logging, data display, and user interface threads may compete with the critical monitoring and alarm threads for use of the processor and other resources.
In order for threads of varying importance to safely coexist in the same system, the operating system that manages the processor and other resources must be able to properly partition the software to guarantee resource availability.
The key word here is guarantee.
Post-design, post-implementation testing cannot be counted on. Safety-critical systems must be safe at all times.
