  • Common Cause Failure Analysis (CCFA) of a Spacecraft Embedded Computing System - TI Journals
    International Journal of Engineering Science, 2013
    Co-Authors: Osamu Saotome, Paulo Elias
    Abstract:

    Abstract: This paper highlights concerns regarding effects of single event effects (SEEs) on the spacecraft Embedded Computing system by applying analysis and mitigation techniques for handling the SEE hazard caused by space radiation (e.g. cosmic rays and solar storms). The purpose is to demonstrate that the common causes of system failures are, in many cases, underestimated in the spacecraft mission risk assessment and consequently the risks associated to external events are under-evaluated and may result in erroneous risk quantification into the risk assessment process. The methodology for performing common cause failure analysis of a spacecraft Embedded Computing system which performs a critical function is called risk tree analysis (RTA) and the risk scenario considered in such analysis is the fact that in Embedded computers there is a potential to malfunction caused by space radiation on electronic hardware within those computers leading to common cause failures at the spacecraft level; that risk scenario is motivated by the hostile environmental conditions where spacecraft is subject for operating without mission losses, either caused by loss of spacecraft or loss of communication link. From launch phase upon to reach Earth’s orbit it usually cross atmosphere levels till enter space operating environment where the cosmic rays and solar storms are more severe than inside Earth’s atmosphere. The space radiation usually cause single event effects on electronic devices within onboard computers causing malfunction at the functional levels of spacecraft. A case study is applied to demonstrate the RTA method and the analysis results are demonstrated at the end of this paper.

  • Integrating Embedded Computing Systems Into High School and Early Undergraduate Education
    IEEE Transactions on Education, 2011
    Co-Authors: Bridget Benson, Arash Arfaee, Ryan Kastner, Rajesh K. Gupta
    Abstract:

    Early exposure to Embedded Computing systems is crucial for students to be prepared for the Embedded Computing demands of today's world. However, exposure to systems knowledge often comes too late in the curriculum to stimulate students' interests and to provide a meaningful difference in how they direct their choice of electives for future education and careers. This paper describes an experience with integrating Embedded Computing systems education into high school and early undergraduate curricula to give students that needed early exposure. It provides assessment data that illustrates the success and limitations of the efforts described as well as the lessons they hold for a reform of the undergraduate curriculum and its impact on high school education.

  • Study and Design of Reconfigurable Embedded Computing System Based on Xilinx SoPC
    Computer Science, 2010
    Co-Authors: Feng Dan
    Abstract:

    The high performance Embedded Computing systems need considerable computational power and flexibility to meet various application requirements.A reconfigurable SoPC design based on Xilinx FPGA was presented.The system uses a dedicated hardware accelerator to process computational intensive tasks,and the accelerator can be dynamically configured during run-time.The hardware processing engine can be coupled to the host system as a CPU coprocessor,a PLB accelerator or an MPMC accelerator.Based on the experimental result that the MPMC accelerator had the highest performance,a reconfigurable MPMC accelerator was designed and integrated into the SoPC system.The experiments used 128-bit AES encryption and decryption as case studies.Features such as hardware resource utilization and reconfi-guration latency for the reconfigurable system were also studied.

  • integrating Embedded Computing systems into high school and early undergraduate education
    Microelectronics Systems Education, 2009
    Co-Authors: Bridget Benson, Arash Arfaee, Choon Kim, Ryan Kastner, Rajesh Gupta
    Abstract:

    Early exposure to Embedded Computing systems is crucial for students to be prepared for the Embedded Computing demands of today's world. Unfortunately, this exposure often comes too late in the curricula to give young students the idea or interest to pursue an Embedded systems education. This paper describes our experience with integrating Embedded Computing systems education into high school and early undergraduate curricula to give students that needed early exposure. We believe that our initial foray has been very successful, thus we are currently pursuing further incorporation of Embedded systems into our undergraduate curriculum.
