Abstract

The programming of real-time applications nowadays involves multitasking using timing demands with microsecond resolution, inter task messaging including semaphores for synchronization of multiple running tasks. For solving this task efficiently a programmer likes to use graphical visualization methods for program flow, messaging and priority dependencies. (more…)

Abstract

Since microcontrollers and DSP's started to be used in power electronics many ideas could be realized and the Optimal Pulse Pattern Modulator was developed together with the Trajectory Controller in order to correct its problem. Working in this kind of research one need a stable and comfortable system which must be flexible to make almost any change. (more…)

Indoor and outdoor LED display vendor TecnoVision, S.p.A. used the open source KA9Q Network Operating System for TCP/IP over Packet Radio to improve product functionality and flexibility, while reducing time to market and design risks. The 26 year-old Italian company makes signs used in advertisement, sport and entertainment events, live concerts, and for road information. (more…)

Abstract

The WIYN Tip-Tilt Module (WTTM) was developed as an adaptive optics solution to image degradation due to atmospheric instability and dynamics. The WTTM was successfully commissioned onto the WIYN 3.5m telescope in February 2002 and it currently undergoing shared risks commissioning. (more…)

Abstract

Proprietary I/O devices are often involved in many computer application systems,especially in embedded systems. In such scenarios, Developers have to develop drivers for these devices to utilize them under some embedded operating system. Traditionally, development of device driver can undertake only after hardware design finishes, for the writing and debugging process involve many… (more…)

Bilatron used uClinux and a new controller with standard network facilities to enable new after-sales services and reduce implementation time in its custom industrial weighing systems. The Central Italian company designs, manufactures, installs, and callibrates weighing systems for industrial applications. (more…)

Abstract

Vendors of modern networking hardware realize that the devices they provide require a great deal of software in order to function effectively. As a result, many hardware vendors provide large amounts of software for use with their devices. However, the prevalent use of the VxWorks operating system has allowed hardware vendors to become careless with the architecture of the driver… (more…)

Abstract

Although in the last years many scheduling algorithms has been proposed, just few of them has been truly implemented in real RTOS. In most cases, the availability of RTOS source code or the complexity and risks involved in introducing new politics in kernel, causes that major part of nowadays RTOS only implements fixed priorities politics. (more…)

Kobold Sistemi used uClinux, open source networking, thttpd, and FreeType to improve product functionaly and gain complete technological ownership of its industrial printing control system. Kobold produces a range of industrial inkjet printers, and currently claims to rank first among worldwide producers of systems for marking, measuring, checkweighting, and labeling. (more…)

Abstract

The paper begins with a short description of the Department's real-time course and its required group projects. This is followed by an overview of the hardware and systems software used in a specific real-time control laboratory assignment. After a discussion of the analysis, design, and implementation of the project, the paper concludes with a brief look at future work. (more…)

Abstract

An embedded real-time system prototype for remote surveillance and control is presented. The system consists of an embedded single-board and a few simulators for devices of which status is monitored and behavior is controlled. These components are connected through a fast switch via which the status information of devices is sent to the single-board computer periodically. (more…)

Gb.Com used embedded Linux, TCP/IP networking, busybox, and other open source software to implement networking capabilities in its process automation and urban waste management systems. Networking capabilities were needed to meet new waste management and taxation laws. Gb.com had previously delivered 15 Windows-based waste management systems, as well as automation units for photovoltaic power generation. (more…)

Abstract

When developing applications under embedded Linux, there is a range of software tools to assist the development process. However, they are so tightly integrated that it is not only difficult to integrate into IDE but hard to add an additional tool. They are communicating with each other through their own protocols so that there is much communication overhead between host and target… (more…)

Abstract

As part of the software development cycle engineers regularly need a systematic method of testing a product prior to release. In the automotive industry this testing is critical to the safety of the users. Complex embedded control units must be tested under precise conditions representative of an automobile. (more…)

Robotics specialist DAS used embedded uClinux, TCL/TK, thhtd, and other open source software to build an embedded controller system for its medical analyzers that it expects to lower production costs while increasing headroom available for customization. Das specializes in medical analyzers delivered through OEM partners. (more…)
