Linux software brings real-time capabilities to embedded systems

Santa Clara, Calif. —MontaVista Software has released MontaVista Linux Professional Edition 5.0, the latest version of its commercial Linux software development platform that provides advanced native Linux real-time capabilities with performance matching that is on par with traditional real-time operating systems.

In addition, MontaVista has dramatically reduced the memory footprint of its fifth-generation OS, giving device manufacturers a high performance, feature rich product for even the smallest connected devices.

According to MontaVista, its Linux Professional Edition 5.0 is first to include the latest advancements in real time technology. The advanced capabilities include high resolution timers and other native Linux real-time enhancements lead by Linux kernel maintainer Ingo Molnar.

MontaVista Linux Professional Edition 5.0 offers average response times (scheduling/preemption latency) in the 5-microsecond range. Linux can address the real-time requirements on a multitude of devices previously only serviced by proprietary real-time operating systems. MontaVista Linux Professional Edition 5.0 puts to rest the myth that Linux is not suited for real-time and embedded applications.

MontaVista Linux Professional Edition 5.0 also debunks perceptions that Linux is big and bulky compared to legacy embedded operating systems. Presenting a small OS footprint continues to be a leading concern for OEMs, despite falling prices for RAM and flash memory. In response, MontaVista Linux Professional Edition 5.0 offers the smallest footprint of any general use Linux platform.

MontaVista offers its customers two highly optimized configurations: one based upon standard glibc library, and another built on the size-conscious uClibc library. Building with uClibc enables a total deployed system footprint under three megabytes — a 75 percent reduction compared with traditional embedded Linux platforms, according to the company. The size of this platform allows device manufacturers to dedicate less precious memory to system code and more to differentiation, and enables Linux to deploy in applications many believed impossible, the company said.
