Working on a Start-Up: A Case for An Applied Entrepreneurship Oriented Course for Senior Undergraduates

In this paper, we describe a new teaching approach whose objective is to implement entrepreneurship-based learning. The proposed teaching approach is essentially a project-based approach, but, with two novel key components that give it the entrepreneurship emphasis. First, the main idea is to divide students into groups of four or five members and have each team go through the process of starting-up a company. This process tries to emulate all steps through which entrepreneurs go when a new start-up idea is taken from concept to product realization. These steps include proposing a novel start-up idea, writing a business plan, coming up with a solution, implementing and testing the solution, and reporting results. The only constraint of this “exercise” is that all start-up ideas must be related to the main topic of the course, which in our case is that of advanced hardware description language and field-programmable gate array (FPGA) digital design. As a second component, each student is required to maintain a so called individual reflective journal (IRJ). Students add new entries of about half a page each week to the IRJ, which plays the role of a diary. The objective of this component is to engage students in thinking about how the course activities tie into the three components of the KEEN framework: curiosity, connections, and creation of value. The projected outcomes of this teaching approach include: 1) help students to develop an entrepreneurial mindset, 2) foster creativity and self-learning, and 3) engage students more and enable them to be proactive and competition-aware

DeSyRe: on-Demand System Reliability

The DeSyRe project builds on-demand adaptive and reliable Systems-on-Chips (SoCs). As fabrication technology scales down, chips are becoming less reliable, thereby incurring increased power and performance costs for fault tolerance. To make matters worse, power density is becoming a significant limiting factor in SoC design, in general. In the face of such changes in the technological landscape, current solutions for fault tolerance are expected to introduce excessive overheads in future systems. Moreover, attempting to design and manufacture a totally defect and fault-free system, would impact heavily, even prohibitively, the design, manufacturing, and testing costs, as well as the system performance and power consumption. In this context, DeSyRe delivers a new generation of systems that are reliable by design at well-balanced power, performance, and design costs. In our attempt to reduce the overheads of fault-tolerance, only a small fraction of the chip is built to be fault-free. This fault-free part is then employed to manage the remaining fault-prone resources of the SoC. The DeSyRe framework is applied to two medical systems with high safety requirements (measured using the IEC 61508 functional safety standard) and tight power and performance constraints

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

Enabling virtual radio functions on software defined radio for future wireless networks

Today's wired networks have become highly flexible, thanks to the fact that an increasing number of functionalities are realized by software rather than dedicated hardware. This trend is still in its early stages for wireless networks, but it has the potential to improve the network's flexibility and resource utilization regarding both the abundant computational resources and the scarce radio spectrum resources. In this work we provide an overview of the enabling technologies for network reconfiguration, such as Network Function Virtualization, Software Defined Networking, and Software Defined Radio. We review frequently used terminology such as softwarization, virtualization, and orchestration, and how these concepts apply to wireless networks. We introduce the concept of Virtual Radio Function, and illustrate how softwarized/virtualized radio functions can be placed and initialized at runtime, allowing radio access technologies and spectrum allocation schemes to be formed dynamically. Finally we focus on embedded Software-Defined Radio as an end device, and illustrate how to realize the placement, initialization and configuration of virtual radio functions on such kind of devices

Using System-on-a-Programmable-Chip Technology to Design Embedded Systems

This paper describes the tools, techniques, and devices used to design embedded products with system–on-a-chip (SoC) type solutions using a large Field Programmable Gate Array (FPGA) with an internal processor core. This new FPGA-based approach is called system-on-a-programmable-chip (SoPC ). The performance tradeoffs present in SoPC systems is compared to more traditional design approaches. Commercial devices, processor cores, and CAD tool flows are described. The issues in SoPC hardware/software design tradeoffs are examined and three example SoPC designs are presented as case studies

An FPGA Multiprocessor System for Undergraduate Study

We present our experiences using multiple soft processor cores on an FPGA to study advanced computer architecture at the undergraduate level. Our system instantiates multiple processor cores on a single FPGA device using the Altera Nios® II soft processor and associated CAD tools. With an easy to use development environment and powerful tools to quickly generate designs, an FPGA platform provides the necessary flexibility to quickly produce a working system. Students are able to easily modify and adapt their designs for a specific application. We demonstrate that multiprocessor systems can be developed, implemented and studied by undergraduate students due to the availability and accessibility of design tools and FPGA development boards. Further, these systems enhance the learning of multiprocessors and aptly compliment advanced computer architecture courses covering topics to include shared memory, synchronization, sequential consistency, and memory coherency
