Embedded Linux for microprocessors

16.04.2004


Embed the open source Linux operating system within a microprocessor and what do you get? For IST project ACEOS it led to demonstration applications for standard Linux networking and voice telecommunications.

Porting Linux to a new processor platform

Project coordinator Gregory Doumenis of the Athens-based system house Global Digital Technologies (GDT) explains why the ACEOS project was considered successful. "We were very happy with the project results because, one, we managed to port Linux successfully to a new architecture, something that only a handful of companies in the world have achieved, and two, it was the first time we had worked with such a broad open source project, so it was a real challenge for us."



Explaining the background to the project, he continues, "We had a problem with a product for small office networking, in that our target market is very cost-sensitive, yet at the same time customers expect to have fully-fledged operating systems for such products. We needed to go back to the drawing board.

"By project close we had ported Linux to the [Infineon] TriCore processor, and had also developed drivers for both Ethernet and voice interfaces. We were able to demonstrate the kernel running and also the applications running on top of it."

The project result, an open source subsystem for networking, provides the foundation for a wide range of future communication interfaces for the residential communications market, with the processing abilities to implement almost any networking function. As such, it facilitates the introduction of advanced communications equipment to residential communications, allowing more players to enter this market sector.

The project was not an easy one, admits Doumenis. The original workplan had to be revised due to the steep learning curve required to understand the Linux kernel, and also because of the additional effort involved in augmenting the development tools for the porting process.

Nevertheless, Doumenis feels that the results have benefited GDT’s competitive position. The project has proven that a small enterprise with limited financial and human resources can produce state-of-the-art products in highly-competitive market niches.

Business contract awarded

A further key milestone for GDT was the award shortly after project close of the first business contract to port Linux to another processor architecture. Hyperstone, a German microprocessor design company, retained GDT to bring mainstream operating system support to its own user community.

"Porting Linux to our single core RISC/DSP processor opens a whole new world of applications, interfaces and drivers," says Dr Matthias Steck, sales and marketing VP at Hyperstone. "With hyLinux [a Linux kernel] our customers reduce their development costs to a minimum ... customers can enter markets quickly and decrease costs during mass production later."

Although now in the commercial domain, hyLinux is still an open source product, says Doumenis. As such the kernel remains available to anyone wishing to develop Linux-based applications for the TriCore processor.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
