<p>Safety critical systems such as nuclear recator systems cannot be shutdown as restrating is a huge process and incurs heavy cost.  The embedded systems which are used for monitoring and controlling the safety critival systems cannot be shut down as well. ES systems which drives safety critical systems must be communicated from remote locations generally through a HOST connected on to Internet. Communication between the HOST and ES system is done using commnd lanaguage which has to be evolved from time to time.  The chnage to the commnd lanauage must be undertaken while the embedded system is up and running, the evolution thus must be dynamic. Many architetcuers have been propsoed in the lieteratuer for evolving  synatx of command lanaguage.The implemntaion of effcient architetcuer as such has not been found in the literatuer without which existing architetcuer as such has no menaing.</p><p>The paper presntes a set of methods using which the syntax evolution of embedded systems as such can be achived. The synatx evolution methods have been applied to a safety critical system that monitors and controls tempartuers within a Nuclear recator system.</p>

Graphics Processing

Recently, advances in technology have enabled embedded systems to be adopted for a variety of applications. Some of these applications require real-time 2D graphics processing running on limited design specifications such as low power consumption and a small area. In order to satisfy such conditions, including a specific 2D graphics accelerator in the embedded system is an effective method. This method reduces the workload of the processor in the embedded system by exploiting the accelerator. The accelerator assists the system to perform 2D graphics processing in real-time. Therefore, a variety of applications that require 2D graphics processing can be implemented with an embedded processor. In this paper, we present a 2D graphics accelerator for tiny embedded systems. The accelerator includes an optimized line-drawing operation based on Bresenham’s algorithm. The optimized operation enables the accelerator to deal with various kinds of 2D graphics processing and to perform the line-drawing instead of the system processor. Moreover, the accelerator also distributes the workload of the processor core by removing the need for the core to access the frame buffer memory. We measure the performance of the accelerator by implementing the processor, including the accelerator, on a field-programmable gate array (FPGA), and ascertaining the possibility of realization by synthesizing using the 180 nm CMOS process.

According to the shortcomings of large volume and high cost about the plate recognition system, an embedded plate recognition system is developed based on the ARM11 processor at lower costs. Taking the embedded Linux system as the software development platform, the system uses graphical user interface to operate and control the machine. Using CMOS camera system as image acquisition device, the system adopts HSV algorithm to realize the image classification on the platform of the embedded plate recognition system. The experimental results show that the embedded system runs stably, can realize the plate classification by color, and has the advantages of small size, low power consumption, convenience for using and so on. The embedded system provides a new thought for plate recognition.

Control Implementation

This paper presents the virtual environment implementation for simulation and design conception of supervision and control systems for mobile robots, that are capable to operate and adapt in different environments and conditions. The purpose of this virtual system is to facilitate the development of embedded architecture systems, emphasizing the implementation of tools that allow the simulation of the kinematic conditions, dynamic and control, with monitoring in real time of all important system points. For this, an open control architecture is proposed, integrating the two main techniques of robotic control implementation in the hardware level: systems microprocessors and reconfigurable hardware devices. The implemented simulator system is composed of a trajectory generating module, a kinematic and dynamic simulator module, and an analysis module of results and errors. All the kinematic and dynamic results obtained during the simulation can be evaluated and visualized in graphs and table formats in the results analysis module, allowing the improvement of the system, minimizing the errors with the necessary adjustments and optimization. For controller implementation in the embedded system, it uses the rapid prototyping which is the technology that allows in set, with the virtual simulation environment, the development of a controller project for mobile robots. The validation and tests had been accomplished with nonholonomic mobile robot models with differential transmission.

This chapter covers the use of UML as a modeling language for embedded systems design. It introduces the UML language, presenting the history of its definition, its main diagrams and characteristics. Using a case study, we show that using the standard UML with its limitations one is not able to model many important characteristics of embedded systems. For that reason, UML provides extension mechanisms that enable one to extend the language for a given domain, through the definition of profiles covering domain-specific applications. Several profiles have been proposed for the embedded systems domain, and some of those that have been standardized by OMG are presented here. A case study is also used to present MARTE, a new profile specifically proposed for the embedded system domain, enabling designers to model aspects like performance and schedulability. This chapter also presents a discussion about the effort to generate code from UML diagrams and analyses the open issues to the successful use of UML in the whole embedded system design flow.

Networking heterogeneous embedded systems is a challenge. Every distributed embedded systems requires that the network is designed specifically considering the heterogeneity that exits among different Microcontroller based systems that are used in developing a distributed embedded system. Communication architecture, which considers the addressing of the individual systems, arbitration, synchronisation, error detection and control etc., needs to be designed considering a specific application. The issue of configuring the slaves has to be addressed. It is also important that the messages, flow of the messages across the individual ES systems must be designed. Every distributed embedded system is different and needs to be dealt with separately. This paper presents an approach that addresses various issues related to networking distributed embedded systems through use of universal serial bus communication protocol (USB). The approach has been applied to design a distributed embedded that monitors and controls temperatures within a Nuclear reactor system.

Embedded systems are often used to monitor and control various dynamic and complex applications. However, with greater accessibility and added features on many embedded systems, more and more systems are being subject to sophisticated and new types of attacks. As a result, the security aspect of embedded systems has become critical design step. TrustZone has become a popular choice for security design solution in systems where resources such as processing power, battery are limited. In TrustZone, two virtual processors called "secure world" and “normal world” run on the same core in a time sliced manner. These worlds have partitioned hardware and software resources, with different modes of operation, isolated memory regions and interrupts. In this paper, the hardware and software architecture of TrustZone is analyzed from the perspective of embedded system security design. Then a mobile-ticketing system based on TrustZone is presented which incorporates standard cryptographic engineering design practices to demonstrate the feasibility and effectiveness of such system. The ticketing system is then simulated and security threat analysis is performed in terms known vulnerabilities such as Buffer Overflow, Static and dynamic code/data tampering, Return Oriented Programming (ROP) exploits, and Man-in-the middle attacks. After evaluating the analysis results with various open source vulnerability analysis tools, it is conclusive that the system design is an effective solution particularly for embedded systems.

This article discusses the resource utilization of embedded systems in the automotive industry. Traditionally, the major cost driver — or resource input — has been regarded as the hardware cost. Issues such as software development costs and maintenance costs have historically been neglected. In order to address this, the article embraces the more comprehensive view on resources that a resource can be regarded as anything which could be thought of as a strength or weakness of a given firm. In this article the major drivers of resource consumption are identified. The work has also included several interviews with employees in order to find empirical data of the embedded systems in vehicles. This paper proposes a method to evaluate the resource efficiency of user functions implemented through the embedded system. By the use of Data Envelopment Analysis — which has proven to be a useful method — the resource utilization of six user functions is evaluated. Future work of particular interest would be to perform a more extensive case study.
