The AXIOM software layers

AXIOM project aims at developing a heterogeneous computing board (SMP-FPGA).The Software Layers developed at the AXIOM project are explained.OmpSs provides an easy way to execute heterogeneous codes in multiple cores. People and objects will soon share the same digital network for information exchange in a world named as the age of the cyber-physical systems. The general expectation is that people and systems will interact in real-time. This poses pressure onto systems design to support increasing demands on computational power, while keeping a low power envelop. Additionally, modular scaling and easy programmability are also important to ensure these systems to become widespread. The whole set of expectations impose scientific and technological challenges that need to be properly addressed.The AXIOM project (Agile, eXtensible, fast I/O Module) will research new hardware/software architectures for cyber-physical systems to meet such expectations. The technical approach aims at solving fundamental problems to enable easy programmability of heterogeneous multi-core multi-board systems. AXIOM proposes the use of the task-based OmpSs programming model, leveraging low-level communication interfaces provided by the hardware. Modular scalability will be possible thanks to a fast interconnect embedded into each module. To this aim, an innovative ARM and FPGA-based board will be designed, with enhanced capabilities for interfacing with the physical world. Its effectiveness will be demonstrated with key scenarios such as Smart Video-Surveillance and Smart Living/Home (domotics).Peer ReviewedPostprint (author's final draft

Cooperative roles of geographic information science in identifying boundary uncertainty : a case study in The Bureau of Land Management\u27s Manzano Wilderness Study Area

Advances in the development and accuracy of Geographic Information Science (GIS) in concert with the rapid development of advanced microprocessors and computer software have resulted in widely available survey data. No longer held captive by the discipline of surveying, this data is currently being used by geographers, cartographers, municipal planners and realtors for display and reproduction. Surveying provides the physical and legal basis for boundary delineation while GIS provides the tools to readily yield information from spatial data, and to economically conduct analyses enabling a more comprehensive understanding of boundary issues. A case study in the Bureau of Land Managements Manzano Wilderness Study Area is used in this thesis to illustrate some of the potential effects of boundary uncertainty and to answer the question \u27What are the roles of GIS and surveying in identifying and resolving boundary uncertainty on public land?\u27\u2

PENGEMBANGAN TRAINER DAN JOBSHEET PALANG PERLINTASAN KERETA API BESERTA VIDEO BLOG MATA PELAJARAN PEMROGRAMAN, MIKROPROSESOR, MIKROKONTROLER

The learning media used in programming, microprocessors and microcontroller have not attracted students responses, because they still use power points. Where the media is still not optimal in its use and many teachers also find it difficult to use a variety software, and the lack of trainers to support the on going learning in class. This can be seen from the results of need assessment. The purpose of this research development is to produce trainers and jobsheets equipped with video blogs that can be used appropriately as learning media for programming, microprocessors and microcontrollers with 3 criteria, namely valid, practical and effective. the research method uses ADDIE. Validation is assessed by the validator, practicality is assessed by students, while effectiveness can be assessed from the learning outcomes of students using the One Shot Case Study research design. From the results of the study, obtained (1) trainer validation obtained results of 83%, can be categorized as very valid and jobsheet validation obtained results of 80.5% categorized as valid while video blog obtained 82% results, can be categorized as very valid, (2) observation of responses students get 85% results can be categorized as very practical, and (3) the student learning outcomes test has largely exceeded the minimum completeness criteria (KKM). From these data, it can be concluded that the trainers and jobsheets that are equipped with video blogs are suitable for use in the subjects of programming, microprocessors and microcontrollers

Shoe-box orbit determination system for SMM preliminary results

The implementation of both sequential and batch methods of estimation on IMP-16 microprocessors was investigated. Simulated data was used from a tracking and data relay satellite whose target satellite was the Solar Maximum Mission. An interesting feature of the hardware was the use of two interconnected IMP-16's. Some preliminary results from the study, as well as the difficulties and advantages in the use of microprocessors, are presented

Vertical Integration and Dis-integration of Computer Firms: A History Friendly Model of the Co-evolution of the Computer and Semiconductor Industries

In this paper we present a history-friendly model of the changing vertical scope of computer firms during the evolution of the computer and semiconductor industries. The model is "history friendly", in that it attempts at replicating some basic, stylized qualitative features of the evolution of vertical integration on the basis of the causal mechanisms and processes which we believe can explain the history. The specific question addressed in the model is set in the context of dynamic and uncertain technological and market environments, characterized by periods of technological revolutions punctuating periods of relative technological stability and smooth technical progress. The model illustrates how the patterns of vertical integration and specialization in the computer industry change as a function of the evolving levels and distribution of firms' capabilities over time and how they depend on the co-evolution of the upstream and downstream sectors. Specific conditions in each of these markets - the size of the external market, the magnitude of the technological discontinuities, the lock-in effects in demand - exert critical effects and feedbacks on market structure and on the vertical scope of firms as time goes by

EXFI: a low cost Fault Injection System for embedded Microprocessor-based Boards

Evaluating the faulty behavior of low-cost embedded microprocessor-based boards is an increasingly important issue, due to their adoption in many safety critical systems. The architecture of a complete Fault Injection environment is proposed, integrating a module for generating a collapsed list of faults, and another for performing their injection and gathering the results. To address this issue, the paper describes a software-implemented Fault Injection approach based on the Trace Exception Mode available in most microprocessors. The authors describe EXFI, a prototypical system implementing the approach, and provide data about some sample benchmark applications. The main advantages of EXFI are the low cost, the good portability, and the high efficienc

Improving reconfigurable systems reliability by combining periodical test and redundancy techniques: a case study

This paper revises and introduces to the field of reconfigurable computer systems, some traditional techniques used in the fields of fault-tolerance and testing of digital circuits. The target area is that of on-board spacecraft electronics, as this class of application is a good candidate for the use of reconfigurable computing technology. Fault tolerant strategies are used in order for the system to adapt itself to the severe conditions found in space. In addition, the paper describes some problems and possible solutions for the use of reconfigurable components, based on programmable logic, in space applications
