An embedded integration prototyping system based on component technique

Nowadays in the development of embedded system, cutting-edge embedded system products are quickly disappearing from the markets because of their short product development period which shortens the product life cycle. Therefore, strengthening its competitiveness and minimizing its development cost can be said to be one of the most important factors. For this motive, an Embedded Integration Prototyping (IP) system based on Component Technique was designed and implemented through this paper. The system is composed of Physical Prototyping (PP) providing the environment in which the product can be tested by using Actuator(Motor), Sensor and reusable Blocks, and Virtual Prototyping (VP) in which visual test on the product can be carried out by applying various components and libraries based on technique related to the computer. And, IP System was built in order to mutually compensate for drawbacks latent in both of physical and virtual prototyping environment by making use of component module. The module will be able to enhance the product competitiveness, through spending less time in developing kinds of the component owning almost same features, using it again for different embedded system products, and accordingly minimizing spent cost and time for developing the component.

Configurable virtual platform environment using SID simulator and Eclipse

For designing and testing embedded software, simulation tools have been used to keep pace with the rapid development of customized hardware parts. SID is a framework for building computer system simulations and SID is made for debugging, testing and verifying embedded software. Though, it is difficult for developers to use SID for their work. In this work, we developed an integrated virtual platform environment based SID simulation framework for a simulator engine and Eclipse for development platform. The proposed system avoids users to manually write the configuration file, and aids loading and connecting components on the fly. We also developed an image file builder and an automation tool for running SID simulation with GDB debugger. Furthermore, users can also monitor/probe the status of all the active components in the target virtual platform during the simulation.

The Integrated Mechanism based on Object between Virtual Prototyping and Physical prototyping

In the virtual prototyping environment, we can simulate details of a target model using many components and libraries provided in advance on a computer. The real prototyping environment provides the test simulation environment as a real product, but we can`t do a detailed simulation of a real product in the virtual prototyping environment, and we can`t do various simulations in the real prototyping environment. So, we made a integrated prototyping environment for linkage of the two types of prototyping environments. Also, in this paper, we developed the integrated prototyping environment based on objects. By this kind of embedded system development environment, we can have the advantages as reuse, flexibility, scalability, and more convenient of product making.

A Flexible Virtual Development Environment for Embedded Systems

On-time delivering of an embedded system solution to market is very crucial because the market is highly competitive and the demands of consumers rapidly change. Virtual development environment increases efficiency of the embedded system development because it enables developers to develop, execute, and verify an embedded system without real hardware. This paper deals with an implementation of a virtual development environment for ARM core-based embedded systems. The environment is developed based on ARMs ARMulator that is an instruction set simulation environment. The developed environment is extended to use SystemC hardware IPs by attaching a SystemC simulation engine to the modeled ASB bus. Therefore, the environment can use both ARMulator-based hardware models and SystemC-based hardware models. By adding hardware IP modules such as Memory controller, LCD controller, Interrupt controller, 1-ch DMA, UART, 2-ch Timer, Watchdog Timer, GPIO Ports and graphical user interface applications, the ARMulator environment is expanded to a virtual development environment for hand-held devices and general applications. In addition, a real-time operating system muC/OS-II is ported to the simulation environment so that the environment can be used to develop muC/OS-II-based application software. A three-task test program verifies the functionality of the hardware IP modules and muC/OS-II operations. Compared to other environments, its construction cost is very low and the environment can be easily modified according to a engineers needs.

Automatic Matching of Protein Spots by Reflecting Their Topology

ABSTRACT Matching spots between two sets of 2-dimensional electrophoresis can make it possible to find out the generation, extinction and change of proteins. Generally protein spots are separated by 2-dimensional electrophoresis. This process makes the position of the same protein spot a little different according to the status of the tissue or the experimental environment. Matching the spots shows that the relation of spots is non-uniform and non-linear transformation. However we can also find that the local relation preserves the topology. This study proposes a matching method motivated by the preservation of the topology. To compare the similarity of the topology, we compared the distance and the angle between neighbour spots. Experimental result shows that the proposed method is effective.Keywords:Spot Matching, Protein, Topology, Electrophoresis 1. 서 론 1) 단백질 연구의 첫 단계는 단백질을 분리하는 것이다. 그 후에 분리한 단백질이 무엇인지를 밝히고, 이어서 그 효과를 결정한다. 세포나 조직에서 단백질을 분리하는 방법으로 2차원 젤 전기영동을 이용한다[1, 2, 25]. 이 방법은 단백질의 두 가지 독립적인 특성인 질량과 전하량을 이용한다[3]. 즉, 질량을 이용하여 수직방향으로 분리하고, 전하량을 이용하여 수평방향으로 단백질을 분리한다. 이 방법을 이용하여 한 번의 분석으로 약 수 백에서 수 천 개의 서로 다른 단백질을 분리할 수 있다. 분리된 단백질은 염료나 은 화합물

Embedded System Integrated Prototyping Mechanism Based on Reusable Component

ABSTRACT Recently, there are many embedded system prototyping tools for helping embedded system designers to trial their product before it releases to the market. A prototype is very important for early embedded system design to grasp the desire functions, to get a good performance, to create delightful user interface, and to increase the valuable of the product. Prototyping tools can be classified by three categories: Physical, Virtual and Modeling prototyping. The integration of these prototyping tools becomes valuable for speed up time-to-market and for decrease design cost when design embedded system. The problem comes up because these tools sometime do not provide an instrument for communicating each other. In this paper, we propose a flexible and reusable mechanism for integrate these tools base on JavaBeans and ActiveX technology. We show how this mechanism can be employed in various prototyping tools.Keywords:Virtual Prototyping, Modeling Prototyping, Physical Prototyping, Integrated Prototyping, Embedded System

A Flexible and Complexity-Aware H/W Design with SystemC Using Integrated Prototyping

In recent years, many embedded system prototyping tools have been developed. Generally, they can be classified into two categories: physical prototyping (PP), virtual prototyping (VP). The integration of these prototyping tools is valuable because it will speed up time-to-market and decrease the cost of design. To reinforce such effects, we introduce a new prototyping concept of modeling prototyping (MP). In this paper, first we propose a flexible and reusable H/W design environment by integrating PP, MP and VP based on JavaBeans. Second, we try to bridge between MP and PP using a new library called SCPP. Since they can communicate with each other, if prototyping modules are distributed across PP and VP, the design complexities in MP will be alleviated. Third, we devise a general template for sensors and actuators in MP to transfer data from a virtual controller to PP. We demonstrate how our proposed integrated prototyping framework can be used flexibly in different tools. We also show how this framework can mitigate the H/W design complexity by taking an example of a simple elevator.

Virtual development environment increases efficiency of embedded system development because it enables developers to develop, execute, and verify an embedded system without real target hardware. This chapter deals with an implementation of a virtual development environment for ARM core-based embedded systems. The environment is based on ARM’s ARMulator simulation environment and extended to use SystemC models by attaching a SystemC simulation engine to the ARMulator. Therefore, the environment can flexibly use both ARMulator-based and SystemC-based hardware models. We developed some hardware IP modules and user interface programs to enrich the environment for hand-held devices or general application development. In addition, a real-time operating system μC/OS-II is ported on the environment so that it can be used to develop multi-thread applications. Compared to other environments, its construction cost is very low and the environment can be easily modified according to an engineer’s needs.

A Device Driver Engine Based on Components for the Embedded Prototyping System

With an influence of digital convergence and a fusion of information technology and existing industries, a lot of methodologies and development environments for embedded system development are being created toward reducing the time-cost required for development of embedded systems. The existing IP(Integrated embedded prototyping) method has advantage which can satisfy the requirement of customer and time-to-market better than virtual prototyping or physical prototyping. However, the integrated prototyping has difficult problem of not being able to use the flexible implementation or testing environments. In this paper, DDEPS(Device Driver Engine for Prototyping System) which has many kinds of customized device drivers for the physical prototyping board connected with the virtual prototyping development tools is proposed to solve the problem. DDEPS was compared with IP method and showed the better performance through the experimental result.
