Real-time Linux comes to Advantech SBCs
RTLinux, the real-time Linux solution from FSM Labs, is to be made available on a range of Advantech single board computers.
RTLinux, the real-time Linux solution from FSM Labs, is to be made available on a range of Advantech single board computers The first qualified board is an Advantech fanless 3.5 Biscuit SBC that uses 10W to run RTLinux hard real time under the full load of sophisticated middleware like Java, databases, and web servers

Serious real-time performance for Linux developers
Embedded software and tools provider SDC has collaborated with single board computer manufacturer Arcom to provide engineers with a complete and ready-to-go real-time Linux platform.
Users can choose to run the industry standard Linux networking stack or FSMLabs' agile zero-copy real-time networking on the built in Ethernet.
"RTLinux really brings out the capabilities of our boards, showing off their impressive speed/power ratios", said Jack Huang, Vice President of Advantech.
"Our customers insist on reducing time to market, so getting the RTLinux complete control software solution already prequalified and tuned to our boards is a major advantage".

Real-time Linux controls shipbuilding robots
Samsung Heavy Industries has been using a family of advanced RTLinux powered robots in its industry leading facilities on Koje Island Korea.
Cort Dougan, FSMLabs Director of Engineering agreed: "Time to market pressures mean that embedded and real-time applications developers are turning to application platforms that can eliminate costly low-value initial engineering efforts and Advantech gives our customers a huge range of high quality, cost effective hardware platforms that are well suited to RTLinux and RTCoreBSD".
FSMLabs RTLinuxPro and RTCoreBSD let developers meet requirements for low-latency hard real-time responsiveness without sensitivity to application load for a wide range of CPU clock rates.
For example, on the Advantech PCM-9386 the worst case context switch from real-time thread to real-time thread is 5.8us.
Scheduling jitter is under 14us without heavy network load and goes up to no more than 52us when both network and graphics load are added.
These measurements are all computed while the Linux "guest" operating system is fully loaded and the network is being stressed.
By comparison, native Linux and BSD limit real-time performance, with response times for comparable operations measured in terms of milliseconds, not microseconds.
The host/guest architecture enables developers of intelligent devices to build high-reliability systems and to support the ever-increasing software content on those devices.
Application developers can take advantage of the RTLinux and RTCoreBSD models to use standard Linux and BSD applications and services in conjunction with POSIX 1003.13 real-time code that runs in the RTCore environment.
"Increasingly, our customers need to make use of sophisticated middleware like Java or advanced network services like IP encryption", said Huang.
"RTLinux allows them to make use of those services from Linux or BSD Unix without fear that critical real-time functions will be delayed".
"Putting Advantech boards on our industry leading automated software build and test racks will give our customers additional assurance that there will not be costly surprises during development or in deployment", said Victor Yodaiken, CEO of FSMLabs.
