  • hardware software co design of Embedded Systems
    Proceedings of the IEEE, 1994
    Co-Authors: Wayne Wolf
    Abstract:

    This paper surveys the design of Embedded Computer Systems, which use software running on programmable Computers to implement System functions. Creating an Embedded Computer System which meets its performance, cost, and design time goals is a hardware-software co-design problem-the design of the hardware and software components influence each other. This paper emphasizes a historical approach to show the relationships between well-understood design problems and the as-yet unsolved problems in co-design. We describe the relationship between hardware and software architecture in the early stages of Embedded System design. We describe analysis techniques for hardware and software relevant to the architectural choices required for hardware-software co-design. We also describe design and synthesis techniques for co-design and related problems. >

  • using a low cost soc Computer and a commercial rtos in an Embedded Systems design course
    IEEE Transactions on Education, 2008
    Co-Authors: James O Hamblen
    Abstract:

    This paper describes the author's experiences using a low-cost System-on-a-chip (SoC) Embedded Computer System and a commercial real-time operating System (RTOS) in the laboratory component of an undergraduate Embedded System design class. The target hardware is a small low-cost X86 SoC Computer System that has a wide range of I/O features. For software development, a popular commercial hard RTOS is used that has been designed for use in Embedded devices. This course covers both hardware and software topics in Embedded Systems, and the course culminates in a final team-based design project. A full set of course materials including a textbook with laboratory tutorials, instructor slides, and code examples has been developed and is available online in electronic form.

  • medical remote monitoring of multiple physiological parameters based on wireless Embedded internet
    IEEE Access, 2020
    Co-Authors: Sheng Ding, Xiaoyan Wang
    Abstract:

    In view of the current situation, that physiological parameter monitoring Systems can only achieve local monitoring, and the multi-physiological parameter monitors are large, expensive, and disadvantageous to remote monitoring. This paper combines Embedded and mobile communication technologies to develop a new type of multi-physiological parameter medical monitoring System with remote data transmission function. First, through the analysis of Embedded System principles, an Embedded Computer System based on ARM is designed. Secondly, the human-Computer interaction interface, data acquisition, and analysis module are designed. Finally, by connecting to the Internet network to communicate with the medical center server, the remote transmission of local detection data and the issuance of alarm signals when dangerous situations occur are realized. The System can collect and display multiple physiological parameters such as heart rate, blood pressure, blood oxygen saturation, and body temperature in real time. The simulation experiment results show that the System’s monitoring function and remote data transmission function meet the design requirements, can quickly and accurately find out-of-standard data, and perform remote alarm. The System is small, easy to expand, stable in data transmission, high in reliability, convenient for remote monitoring and data sharing, and is an ideal monitoring device for hospitals and community medical centers.

  • The design and implementation of the VuMan wearable Computer
    2018
    Co-Authors: Daniel P. Siewiorek, Carnegie Mellon University.engineering Design Research Center.
    Abstract:

    Abstract: "This paper describes the design and implementation of a novel Embedded Computer System with a visual interface -- VuMan 2. VuMan 2 is the most recent wearable Computer artifact designed and implemented at Carnegie Mellon University. VuMan 2's capabilities and an evaluation of its design process are presented. Our learning experience and experimental results should contribute to a better understanding of new emerging information technology concepts as well as the process of Embedded Systems design.

  • a case study in Embedded System design the vuman 2 wearable Computer
    IEEE Design & Test of Computers, 1993
    Co-Authors: A Smailagic, Daniel P. Siewiorek
    Abstract:

    The development of an Embedded-Computer System with a visual interface is described. The authors detail the use of a target System simulator and a prototype printed circuit board (PCB), which facilitated a concurrent approach to the design of the hardware, software, and housing. They outline this codesign process and illustrate its effects with comparative data from the earlier VuMan 1 project. >

  • a tool set for integrated software and hardware dependability analysis using the architecture analysis and design language aadl and error model annex
    International Conference on Engineering of Complex Computer Systems, 2011
    Co-Authors: Myron Hecht, Alexander Lam, Christopher J Vogl
    Abstract:

    Cyberphysical (Embedded) Computer System availability and reliability can be modeled and assessed using the Architecture Analysis and Design Language (AADL) and its Error Model Annex. AADL can represent Systems at multiple levels of abstraction. Therefore, analyses can be performed early and often throughout the development process thereby minimizing the cost and schedule impact of changes. We discuss how the AADL and its Error Model Annex can be used for automated generation of a reliability/dependability model. We then describe a tool set to graphically create AADL System architecture and error behavior files that are then transformed into Stochastic Petri Nets (SPN) and Stochastic Activity Network (SAN) representations and demonstrate its use using a generic satellite as an example.
