This book was released on 2000-06-01 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low availability, high cost, and poor performance of radiation hardened (rad-hard) equipment has driven the market to rely on commercial-off- the-shelf (COTS) equipment for the computing needs of today's spacecraft. This thesis describes the tailoring of a COTS embedded real-time operating system and design of a human-computer interface (HCI) for a triple modular redundant (TMR) fault-tolerant microprocessor for use in space-based applications. Once disadvantage of using COTS hardware components is their susceptibility to the radiation effects present in the space environment. and specifically, radiation- induced single-event upsets (SEUs). In the event of an SEU, a fault-tolerant system can mitigate the effects of the upset and continue to process from the last known correct system state. The TMR basic hardware design used for this research is an acceptable fault-tolerant design candidate for the main processor for space-based applications. We found that a COTS embedded real-time operating system could be tailored to support the TMR hardware. The HCI accepts serial data from the TMR, correctly identifies the source of the error, allows for processor mode selection and provides system- and board-level reset capabilities. The tailored operating system combined with the HCI is a viable software imp- lementation to support hardware-based fault-tolerant computing in a space environment.
Download or read book Feasibility Analysis and Design of a Fault Tolerant Computing System written by Huseyin B. Eken and published by . This book was released on 2001-03-01 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to analyze and determine the feasibility of implementing a fault tolerant computing system that is able to function in the presence of radiation induced Single Event Upsets (SEU) by using the Triple Modular Redundancy (TMR) technique with 64-bit Commercial-Off-The- Shelf (COTS) microprocessors. Due to the radiation environment in space, electronic devices must be designed to tolerate the radiation effects. While there are radiation-hardened devices that can tolerate radiation effects, they offer lower performance and higher cost than COTS devices. On the other hand, COTS devices offer lower cost, orders of magnitude higher performance, shorter design time and better software availability and compatibility. However, COTS devices are susceptible to the radiation effects. In order to use COTS devices in space environment, a fault tolerance technique such as TMR needs to be implemented. This thesis presents the design and analysis of a TMR 64-bit COTS microprocessor implementation. The system incorporates three 64-bit microprocessors, the memory system including SRAM and PROM memory modules and the programmable logic devices that are used to implement the IMR technique. The validity of the design is verified by the timing analysis conducted on read and write operations.
Download or read book Implementation of a Fault Tolerant Computing Testbed written by David C. Summers and published by . This book was released on 2000-06-01 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: With spacecraft designs placing more emphasis on reduced cost, faster design time, and higher performance, it is easy to understand why more commercial-off-the-shelf (COTS) devices are being used in space based applications. The COTS devices offer spacecraft designers shorter design-to- orbit times, lower system costs, orders of magnitude better performance, and a much better software availability than their radiation hardened (radhard) counterparts. The major drawback to using COTS devices in space is their increased susceptibility to the effects of radiation, single event upsets (SEUs) in particular. This thesis will focus on the implementation of a fault tolerant computer system. The hardware design presented here has two different benefits. First, the system can act as a software testbed, which allows testing of software fault tolerant techniques in the presence of radiation induced SEUs. This allows the testing of the software algorithms in the environment they were designed to operate in without the expense of being placed in orbit. Additionally, the design can be used as a hybrid fault tolerant computer system. By combining the masking ability of the hardware with supporting software, the system can mask out and reset processor errors in real time. The design layout will be presented using OrCAD schematics.

Download or read book Advanced Computing written by Michael Bader and published by Springer Science & Business Media. This book was released on 2013-09-26 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume collects review articles that summarize research conducted at the Munich Centre of Advanced Computing (MAC) from 2008 to 2012. The articles address the increasing gap between what should be possible in Computational Science and Engineering due to recent advances in algorithms, hardware, and networks, and what can actually be achieved in practice; they also examine novel computing architectures, where computation itself is a multifaceted process, with hardware awareness or ubiquitous parallelism due to many-core systems being just two of the challenges faced. Topics cover both the methodological aspects of advanced computing (algorithms, parallel computing, data exploration, software engineering) and cutting-edge applications from the fields of chemistry, the geosciences, civil and mechanical engineering, etc., reflecting the highly interdisciplinary nature of the Munich Centre of Advanced Computing.
Download or read book War in Space written by Linda Dawson and published by Springer. This book was released on 2019-01-14 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the recent influx of spaceflight and satellite launches, the region of outer space has become saturated with vital technology used for communication and surveillance and the functioning of business and government. But what would happen if these capabilities were disrupted or even destroyed? How would we react if faced with a full-scale blackout of satellite communications? What can and has happened following the destruction of a satellite? In the short term, the aftermath would send thousands of fragments orbiting Earth as space debris. In the longer term, the ramifications of such an event on Earth and in space would be alarming, to say the least. This book takes a look at such crippling scenarios and how countries around the world might respond in their wake. It describes the aggressive actions that nations could take and the technologies that could be leveraged to gain power and control over assets, as well as to initiate war in the theater of outer space. The ways that a country's vital capabilities could be disarmed in such a setting are investigated. In addition, the book discusses our past and present political climate, including which countries currently have these abilities and who the aggressive players already are. Finally, it addresses promising research and space technology that could be used to protect us from those interested in destroying the world's vital systems.
