  • Recently, most embedded systems have the multi-functions mixed the hardware with the software. The existing sequence programming methods are not suitable to implement the embedded system with multi-functions. So, it can be overcome the limit of a facility implementation by introducing the operating system in system. Also, due to the requirement about the better convenient and comfortable meeting or lecture environment, the necessity of electronic white-board is getting higher. Specially, the education using multimedia information is much more desirable for various and improved lecture at the high school and the university. But the sequence program which have been managed in existing electronic white-board system has some difficulties to achieve the software-oriented systems which has to accomplish many functions. In this paper, we propose the method to implement a facility of electronic white-board through using the embedded linux with excellent performance. The embedded linux presents the powerful software environment for the implementation of an embedded system and makes the realization of many various functions easy because it follows kernel characteristics of linux. In this paper, we describe the details for the structure of hardware, kernel source and device driver of a developed electronic white-board.

  • In this paper, we have designed a Home Networking System using an embedded linux board. The system based on the World-Wide-Web is composed of three parts - a Server, a Client and a Simulator. The Home Networking Server is built in an embedded board using an embedded linux kernel. A web-server and Home Networking Server Seryice Demon programming with a Jaya-Language is included in the board. Clients can connect to the server board using a web-browser in the desktop computer, PDA or any other machines which include a web-browser. For this purpose, we made the client program using a Java-Applet. So, the clients who connect to the server for the control of the applications, download the class-file and execute the client-program in the web-browser. So, the clients don't need any other programs to control the applications from a remote place. The size of server board is very small (86.3$\times$74mm), which makes it very useful not only for the Home-Networking-System but also in many other fields, e.g., embedded robot control system, etc. Using an embedded board instead of a desktop computer is good for a simple network environment and it occupies only a small space to make the system.

  • In this paper, we implement a place information system for missing children using embedded board. In the implementation, the embedded board receives location information from GPS satellites, parsing GGA information which includes current time and location coordinates from the satellite information and sends them to the location management server. The server locates a missing child using the location information from embedded board together with server database. We implement an application program for the system. The program shows current location of a child and its moving path and browses the corresponding map from coordinates mapping.

  • We have designed LED display system using ARM7TDMI processor and implemented hangul input and output. This system is easily extensible because controller board and LED matrix board were designed one module. Possible Input Methods of LED display system are PC, PDA and remote controller's wired and wireless communication. We have ported QT/Embedded 2.3.7 with touch panel Input at embedded board of Linux OS 2.4.18 and PXA255 Processor based. QT Application which we coded is able to input displaying text using ethernet communication on embedded system. Many of indicating text data is able to be saved because only korean alphabet codes are stored for data which users want displaying.

  • 8-layer printed circuit board is designed and implemented for triple band(2.3/2.5/3.5GHz) m-WiMAX system. In order to maintain excellent RF performance, low dielectric constant material is used for implementation of the printed circuit board. Also, embedded printed circuit board which embed passive devices is manufactured to reduce total system area. As a result, total system area is cut off by 9%. Triple band m-WiMAX system is produced using embedded printed circuit board. Furthermore, internet connecting test is performed and proved successful running of the system. The developed embedded printed circuit board will provide a effective solution for system area reduction and low loss signal RF communication system.

  • This paper proposes a multi-core cooperative computing structure considering the heterogeneous features of automotive embedded on-chip software. The automotive embedded software has the heterogeneous execution flow properties for various hardware drives. Software developed with a homogeneous execution flow without considering these properties will incur inefficient overhead due to core latency and load. The proposed method was evaluated on an target board on which a automotive MCU (micro-controller unit) with built-in multi-cores was mounted. We demonstrate an overhead reduction when software including common embedded system tasks, such as ADC sampling, DSP operations, and communication interfaces, are implemented in a heterogeneous execution flow. When we used the proposed method, embedded software was able to take advantage of idle states that occur between heterogeneous tasks to make efficient use of the resources on the board. As a result of the experiments, the power consumption of the board decreased by 42.11% compared to the baseline. Furthermore, the time required to process the same amount of sampling data was reduced by 27.09%. Experimental results validate the efficiency of the proposed multi-core cooperative heterogeneous embedded software execution technique.

  • In this paper, we propose the development of an embedded board for construction of smart factory. The proposed embedded board for construction of smart factory consists of main module, ADC module, I/O module. Main module is a main calculating device which includes communication pard that allows interface with external device with using industrial protocol and is ported operating system makes board operating into. ADC module takes part in transferring digital signal has converted from electrical signal to the main module from the external sensor which is installed on the field. I/O module is an input and output module which transfers to the main module about a status, alarm, command signal of field device and it has a function that blocks external noises from field device with isolation circuit into it. In order to evaluate the performance of the proposed embedded board for construction of smart factory, it has been tested by an authorized testing institute. As a result, quantity of interacting protocol was 5, speed of hardware clock synchronization was under 10us and operating time of battery without source power was over 8 hours. It produced the same result as the world's highest level.
