    Embedded system is the application specific computing system that embedded in other application, to perform some special information processing functionalities. Embedded system is composed of software part (including embedded system software and application software) and hardware part (including embedded processors, memory, ASICs, IO circuit et al). In order to ensure design quality and efficiency of embedded system, it not only requires the designers to do hardware/software co-design, but also requires experts from different domains to cooperate. Existing embedded system design methods and environments mainly support hardware/software co-design, but they can't support the cooperation among experts from different domains. In this paper, we present a distributed cooperative design method for embedded system and developed the corresponding design environment, main features are: We employ mobile agent and Web service technology to establish the distributed cooperative design environment. This distributed network environment can support experts from different domains perform embedded system virtual prototyping modeling and simulation, hardware/software partitioning and performance evaluation cooperatively, this environment also supports traditional embedded system hardware/software co-design and design reusing method. Application experiment on the embedded system design of satellite navigation and positioning device indicate that, our distributed cooperative design method and design environment of embedded system improves the design quality and efficiency greatly.

    As the increasing of system performance and computing power, embedded systems are more complicated and interactive. Therefore, operating system (OS) plays a more important role in embedded systems to utilize various hardware and software resources. However, no OS can meet all requirements of various embedded systems. Due to the advance of reconfigurable processors, system requirements can be more dynamic. Embedded OS has becoming more critical in the development of embedded systems and thus there is a strong need of configurable embedded OS to better and faster build up the target system. In this paper, we propose a configurable OS, called COS, based on SOA (service-oriented architecture) for embedded SoC (system on a chip) systems to build an application specific OS according to the system requirements. COS can be easily configured to better utilize the resources of the target embedded platform and have better support to the embedded application. Moreover, the COS can easily extend new features or functionalities of other OSes and even be adapted to the designs of other OSes. We implement COS on an ARM platform to prove its configurability and also evaluate its overhead. We believe that COS can be configured to meet the various requirements in embedded SoC systems and help to speed up the embedded system development process View full abstract»

    Panel: Embedded Systems and Hardware-Software Co-Design: Panacea or Pandora's Box?

    An embedded computer system (or simply embedded system) is a digital system which uses a microprocessor running software to implement some or all of its functions. Hardware-software co-design is any design technique for the creation of systems with both hardware and software components. Embedded systems are clearly important---microprocessors are used in products ranging from microwave ovens to laser printers to engine controllers. This panel considers what makes embedded system design difficult today and how CAD and CASE can help. Embedded system must be designed under sever constraints. On the one hand, they must often meet performance goals to be viable in the marketplace. On the otherhand, manufacturing cost is important---microprocessors are often used to save money, and the designer wastes money by using a larger processor than necessary. Time-to-market is often critical, since companies often believe (perhaps erroneously) that software implementations will be finished faster. Finally, embedded systems must often be expandable---companies expect to roll out new, improved versions of products by taking advantage of the existing hardware platform and software base. The design of an embedded system may require delicate balancing of hardware and software resource requirements. Performance requirements may force some operations to be done in custom hardware. In current design practice, hardware-software partitioning is often done too early, leading to suboptimal design times and delays in software development. Even if no custom hardware is required, the embedded system designer must choose a hardware architecture on which the software is to be executed. The designer must choose the size and number of CPUs, memory size, peripherals, and so forth. Hardware and software elements must be designed simultaneously, then integrated into a complete system. Concurrent design techniques help to keep track of the design and ensure that constraints are satisfied. Embedded system design practice today is about where VLSI design practice was in the late 1970's. Complex chips were designed before Mead and Conway, but with only the vaguest notion of design abstraction or methodology and with primitive tools. The VLSI revolution helped designers understand their chip designs- more abstractly, which led to the development of methodologies and tools which vastly improved designer productivity. Similarly, embedded systems are designed today with only the crudest of tools and with very little learning from one system to the next. We need to understand the common characteristics of embedded systems and develop tools which automate specific steps in the embedded system design process. Only by rationalizing and automating embedded system design can we take advantage of the vast increases in programmable computing power delivered by VLSI. View full abstract»

    File system reliability has always been a strong concern in the embedded operating system. This reliability frequently involves a choice between raw performance and integrity guarantees. Snapshot technique is to create an instant image of the file system with little processing and space overheads. It performs data protection and provides the continuous data service during backup. To improve the reliability and stability of the embedded file system, we propose an embedded file system meta-data snapshot for the ext2 file system, which based on the asynchronous/synchronous I/O coexisted strategy of media file storage, in muCLinux kernel 2.4.26. As we all know, embedded systems usually have very strict memory, processor, and I/O limitations that must play factors in designing an embedded system. Moreover, the cost of additional system management complexity and disk latency are the key factors that directly affect the file system performance. Because of these limits, we introduce a media storage file system (MSFS). The main technique of this File system is MSnap (meta-date virtual view snapshot technique). Unlike other snapshot technologies; it dose not needs massive snapshot volume and complexity implementation. Experimental results show that MSnap induces less overhead and has higher performance, reliability than traditional snapshot system. View full abstract»

    An embedded system, a digital electronic system being embedded in a larger device, is the system to be configured to fulfill specific demands of customers from some market segmentations. This nature complicates the design of an embedded system itself. Traditional embedded system marketers usually defined the systems based on their intuition, which could be subjective and misleading. To fulfill different customers' demands from various market segmentations, the concept of “user-centered design” can be leveraged. Thus, this research aims to resolve this issue by introducing a novel fuzzy multiple criteria decision making (FMCDM) based embedded system design method by introducing the concept of “emotional design“. By using this method, customer needs can be elicited through explorations of their emotions. The fuzzy analytic hierarchical process (FAHP) will be leveraged for deriving the relative weights. Further, considering the characteristic of inter-dependences between criteria, the non-additive fuzzy integral method will be introduced to aggregate the performance scores on each component of the embedded system platform. In this paper, an empirical study on an embedded system design of a handset being designed by one of the world's largest IT (information technology) manufacturers will be leveraged for demonstrating the feasibility of this framework. A satisfying mobile phone can be designed based on the newly proposed FMCDM framework. And this methodology can be used to configure any embedded system to be embedded in other consumer electronics products. View full abstract»

    In embedded system designs, most researches are involved in the hardware or software design, separately. These methods are effective and efficient for hardware or software (HW/SW) building, respectively. In an entire embedded system, hardware and software co-exist. In addition, software may consist of system and application parts. Thus these HW/SW methods cannot provide an overall and effective evaluation for the performance and cost of an entire embedded system. With the flexibility and configurability of Field Programmable Gate Arrays (FPGAs), this paper investigates an application-oriented top-down scheme (AOTDS) of FPGA-based embedded system design from the application layer down to hardware system. The AOTDS can help reduce the redundancy of system resources and increase their reuse. Since embedded systems are inherently application-specific, rather than all-round like general purpose computers, the AOTDS is natural and efficient for embedded system designs. The efficiency and effectiveness of AOTDS are verified through the implementation of an FPGA-based embedded system with 3D graphics applications. View full abstract»

    Pattern recognition (PR) based on electromyographic (EMG) signals has been developed for multifunctional artificial arms for decades. However, assessment of EMG PR control for daily prosthesis use is still limited. One of the major barriers is the lack of a portable and configurable embedded system to implement the EMG PR control. This paper aimed to design an open and configurable embedded system for EMG PR implementation so that researchers can easily modify and optimize the control algorithms upon our designed platform and test the EMG PR control outside of the lab environments. The open platform was built on an open source embedded Linux Operating System running a high-performance Gumstix board. Both the hardware and software system framework were openly designed. The system was highly flexible in terms of number of inputs/outputs and calibration interfaces used. Such flexibility enabled easy integration of our embedded system with different types of commercialized or prototypic artificial arms. Thus far, our system was portable for take-home use. Additionally, compared with previously reported embedded systems for EMG PR implementation, our system demonstrated improved processing efficiency and high system precision. Our long-term goals are (1) to develop a wearable and practical EMG PR-based control for multifunctional artificial arms, and (2) to quantify the benefits of EMG PR-based control over conventional myoelectric prosthesis control in a home setting.

    We describe the design and implementation of a hybrid intelligent surveillance system consisting of an embedded system and a personal computer (PC)-based system. The embedded system performs some of the image processing tasks and sends the processed data to a PC. The PC tracks persons and recognizes two-person interactions by using a grayscale side-view image sequence captured by a stationary camera. Based on our previous research, we explored the optimum division of tasks between the embedded system and the PC, simulated the embedded system using dataflow models in Ptolemy, and prototyped the embedded systems in real-time hardware and software using a 16-bit CISC microprocessor. This embedded system processes one frame image in 89 ms, which is within three frame-cycle periods for a 30 Hz video system. In addition, the real-time embedded system prototype uses 5.7 Kbytes of program memory, 854 Kbytes of internal data memory and 2 Mbytes external DRAM. View full abstract»

    NTP is a protocol designed to synchronize the clocks of computers over a network. This paper will implement the NTP on an embedded system to serve as a server of the NTP Pool Project. The developed embedded system is based on the embedded Linux operating system. The benefits of utilization of the embedded Linux system rely on its lower power consumption, high system stability, the small size of whole system including hardware and software, and no extra cost protected by the GPL license. All these characteristics will provide the embedded Linux system to be a suitable system for the implementation of the NTP that will need the services provided by many non-centralized servers. By setting multiple NTP servers in each network domain and utilizing NTP Pool Project guidelines, it will help to evenly distribute the throughput of each server and enhance the stability of the system. This paper will provide the detailed introduction on the protocol of NTP and the framework of the NTP Pool Project, the development of the NTP on the embedded system, and followed by the suggestions of the implementation of the NTP.

    Two networked embedded systems for existent power equipment are designed in this paper to achieve the goal of remote control and monitoring. Since the basic requirement of industrial control and monitoring systems is the response time; therefore, time constraint is the first consideration in designing networked embedded systems. Telnet and Web server are the commonly used Internet functions for embedded systems. The embedded Web server based system is definitely the better choice for power equipment control and monitoring. However, due to the response time constraint, memory capacity and processing power of embedded systems, a Telnet based system is also presented in this paper. Since RS232 is the most popular communication media for existent power equipment; the developed embedded system is deigned to communicate with the existent power equipment by RS232. After the data retrieved from the power equipment, the designed system can transmit those data to remote control center via the Internet. The experimental platform shown in this paper is a Samsung S3C4510-based embedded system. The embedded system features uCLinux operating system; therefore, the design and implementation of these proposed networked systems could be more effective. Experimental results show that the designed networked embedded systems can be integrated into power equipment effectively. View full abstract»

    Embedded control systems play a very important role in the modern industry, which fulfill various complicated and durable control tasks in automation industry. A typical embedded control system consist of a microprocessor based hardware and a set of software running on top of it. Due to rapid upgrading and function changing, the life cycle of embedded control system becomes shorter and shorter. For the current embedded control system solution, it is usually lack of reconfigurability and secondary development ability. This makes the reusing of the existing design very hard, which usually involves intensive modification or even rewriting of software codes. To ease such kind of system design as well as shorten program coding period, an engine based design method is proposed in this paper. This method separates the embedded system function description and its executor as a function description data (FDD) and an engine. The FDD used by the engine stores the system control logic and processing rules of external/internal stimuli. The engine responses to these stimuli and processes them according to the description of FDD. A Statechart based modeling tool is applied to conduct the FDD design. By doing so, whenever the system function changing or updating is required, only its FDD needs to be regenerated, the Engine remains the same. The embedded control system development burden can be then greatly simplified. Also its secondary development ability can be realized even at shop floor level. A case study of a CNC system is introduced to verify the feasibility of the proposed method. View full abstract»

    Embedded system design is a topic of interest to multidisciplinary fields including electrical engineering and computer science. In order to correctly focus on the correct aspects of embedded system design, be it hardware for electrical engineering students, or software for computer science students, seamless connectivity between the hardware and software aspects needs to be provided. One approach to provide students from both fields with practical experience is to develop a transparent bridge between the hardware and software layers of the embedded system design. In this paper we demonstrate a universal serial bus/serial peripheral interface (USB/SPI) transparent bridge to interface an embedded system to a personal computer. The bridge consists of a hardware module that transmits the embedded system data through SPI to a PC using USB. A device driver for the USB/SPI bridge provides a straightforward application programming interface to the embedded system. The bridge can aide students studying embedded system design and students studying computer software development to collaborate on design projects. View full abstract»

    The traditional development of hardware and software of embedded system is non-synchronous, low efficiency and the design knowledge can not be reused. To solve these problems, a new developing method, Reconfigurable Design Method (RDM) is presented in this paper. In this method, the embedded system architecture is abstracted as a class of product family, in which, the components of embedded system can be modularized, the modules correspond to the different components of the product family. The ontology is employed to represent the concepts and design instances of the embedded system as well. A knowledge system is developed to configure the software and hardware components of the embedded system. The control system of a electronic Universal Testing Machine(UTM) is examplified to verify RDM presented in this paper. View full abstract»

    Today, the embedded systems field is growing rapidly, ranging from low-end systems such as cellular phones, PDAs, smart cards to high-end systems such as gateways, firewalls, storage servers, and web server. Security of embedded system becomes a paramount issue in embedded system design. Compared to an embedded system's functionality and other design metric (e.g., area, performance, power), security is currently specified by system architects in a vague and imprecise manner. This paper proposes a fuzzy integrated security evaluation method based on man-computer combined data collection and fuzzy expert evaluation in Delphi method. The method could reduce the subjectivity of expert evaluation and alleviate the difficulty of data collection and makes possible a better combination of qualitative and quantitative evaluations. Firstly, the hierarchy structure model of embedded system security is constructed. Secondly, according to data collected and the evaluation comment of each expert, the subjection degree matrix is constructed. Finally, a new concept of ldquodegree of assurancerdquo is presented for the quantificational evaluation of embedded system security. In this paper a study of a wireless biometric authentication device is also shown. The case illustrates that the method can be easily used and its results conform to the actual situation.
