A brand new embedded Linux software company recently joined the growing number of Asian companies that are embedding Linux within consumer Internet and information appliances. During the week of Comdex Fall 2000, Taiwan-based Esfia unleashed a volley of product and technology announcements and launched its new website ((more…)

TimeSys Corporation, a supplier of Embedded Linux software for real-time system applications, today announced the launch of its Japan-based sales and support office, TimeSys Japan, K.K. Located in suburban Tokyo, in the college-town Kichijoji, the new TimeSys facility will target Japan's rich automotive, consumer electronic, telecommunications, and aerospace industries. (more…)

This work presents a position monitoring system to generate displays showing the position of trains, time between trains, seconds early/late for each train, and alarms. Alarms will be generated when trains are too close, unexpected events are received, or trains do not cross subsequent sensors when expected. (more…)

In the near future, smartphones will become good enough for most PC users' usual purposes and any device can be connected to Internet. Finally PC and smartphone will converge as the next generation handheld device, which will be always best connected. Symbian, Windows Mobile, Linux, RIM, MacOS are the top 5 OSes, which compete in this fast-growing market segment. (more…)

The Dresden Real-Time Operating Systems Project (DROPS) is a research project aiming at the support of applications with Quality of Service requirements. In the DROPS project a key component is L4Linux, the Linux server on top of the L4 microkernel. Now DROPS could provide to concurrent execution of many instances of L4Linux like Xen but there is no feasible interface to implement communication between… (more…)

Automation technology lacks an established platform independent, high-level, object oriented real-time capable communication standard, which is based on standard Ethernet hardware and drivers. ACE/TAO is an Open Source implementation of the OMG Real-Time CORBA Specification and might fill this gap. (more…)

RTLinux-GPL1 is an RTOS which uses a dual-kernel approach, that is, executing a real-time kernel (RTLinux-GPL itself) jointly with a general purpose OS (Linux). By using this approach, complex real-time application with both, hard and soft real-time requirements can be implemented easier. (more…)

Real-time I/O scheduling, specifically disk scheduling, has frequently received far less attention than other aspects of real-time theory. Nevertheless, several proposals have addressed this area meaning to merge the real-time CPU scheduling along with traditional I/O scheduling to provide real-time disk response. (more…)

The processor Cell Broadband Engine (Cell/B.E.) is used inside the Playstation 3. The Cell/B.E. is a multi-core processor with heterogenous cores. Each core has its own memory. But all cores can communicate with each other using a high speed bus. (more…)

Xtratum is a nanokernel designed for providing domain support to execute concurrently several operating systems on a single computer. These domains are in the same hardware but running temporally and spatially isolated. As a very thin virtualization layer virtualizing the essential resources (interrupt, timer, memory, and CPU), XtratuM is suitable for embedded real-time systems, and at least one of those… (more…)

A PROFINET system built out of ERTEC Switch ASICs allows to keep the nodes of a network synchronized with an accuracy below 1sec. While still allowing regular IP communication, it also guarantees the timely arrival of cyclic messages below that mark. These features are particularly required for the motion control part of automation systems. (more…)

West Des Moines, IA — (press release excerpt) — Icon Laboratories today announced the expansion of its embedded Linux software development services. The company has been involved with Linux-based embedded projects for the past 18 months, including telecommunications, broadband wireless networking, and set-top box projects, and has been successful in reducing time-to-market while allowing the client to… (more…)

The emergence of slice-based computing model has raised high demand on replacing the interface- based addressing model with user-oriented addressing (UOA) paradigm. Assigning IP addresses to users instead of interfaces or hosts help us to realize high-granularity controls on port resource utilization, identity authentication, and quality of service. (more…)

The LinuxDevices.com “Embedded Linux GUI/Windowing Quick Reference Guide” is a comprehensive guide to support for the graphics requirements of Embedded Linux based systems and devices. The guide covers the full range of embedded system alternatives to standard desktop software components, including low-level drivers, graphics servers, windowing enviroments, GUI toolkits, and browsers .
