Integrated Design and Implementation of Embedded Control Systems with Scilab
Embedded systems are playing an increasingly important role in control
engineering. Despite their popularity, embedded systems are generally subject
to resource constraints and it is therefore difficult to build complex control
systems on embedded platforms. Traditionally, the design and implementation of
control systems are often separated, which causes the development of embedded
control systems to be highly time-consuming and costly. To address these
problems, this paper presents a low-cost, reusable, reconfigurable platform
that enables integrated design and implementation of embedded control systems.
To minimize the cost, free and open source software packages such as Linux and
Scilab are used. Scilab is ported to the embedded ARM-Linux system. The drivers
for interfacing Scilab with several communication protocols including serial,
Ethernet, and Modbus are developed. Experiments are conducted to test the
developed embedded platform. The use of Scilab enables implementation of
complex control algorithms on embedded platforms. With the developed platform,
it is possible to perform all phases of the development cycle of embedded
control systems in a unified environment, thus facilitating the reduction of
development time and cost.Comment: 15 pages, 14 figures; Open Access at

Constructivist Multi-Access Lab Approach in Teaching FPGA Systems Design with LabVIEW
Embedded systems play vital role in modern
applications [1]. They can be found in autos, washing
machines, electrical appliances and even in toys. FPGAs are
the most recent computing technology that is used in embedded
systems. There is an increasing demand on FPGA
based embedded systems, in particular, for applications that
require rapid time responses. Engineering education curricula
needs to respond to the increasing industrial demand of
using FPGAs by introducing new syllabus for teaching and
learning this subject. This paper describes the development
of new course material for teaching FPGA-based embedded
systems design by using ‘G’ Programming Language of
LabVIEW. A general overview of FPGA role in engineering
education is provided. A survey of available Hardware
Programming Languages for FPGAs is presented. A survey
about LabVIEW utilization in engineering education is
investigated; this is followed by a motivation section of why
to use LabVIEW graphical programming in teaching and its
capabilities. Then, a section of choosing a suitable kit for the
course is laid down. Later, constructivist closed-loop model
the FPGA course has been proposed in accordance with [2-
4; 80,86,89,92]. The paper is proposing a pedagogical
framework for FPGA teaching; pedagogical evaluation will
be conducted in future studies. The complete study has been
done at the Faculty of Electrical and Electronic Engineering,

A comprehensive approach to MPSoC security: achieving network-on-chip security : a hierarchical, multi-agent approach
Multiprocessor Systems-on-Chip (MPSoCs) are pervading our lives, acquiring ever increasing relevance in a large number of applications, including even safety-critical ones. MPSoCs, are becoming increasingly complex and heterogeneous; the Networks on Chip (NoC paradigm has been introduced to support scalable on-chip communication, and (in some cases) even with reconfigurability support. The increased complexity as well as the networking approach in turn make security aspects more critical. In this work we propose and implement a hierarchical multi-agent approach providing solutions to secure NoC based MPSoCs at different levels of design. We develop a flexible, scalable and modular structure that integrates protection of different elements in the MPSoC (e.g. memory, processors) from different attack scenarios. Rather than focusing on protection strategies specifically devised for an individual attack or a particular core, this work aims at providing a comprehensive, system-level protection strategy: this constitutes its main methodological contribution. We prove feasibility of the concepts via prototype realization in FPGA technology
