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

The hArtes Tool Chain
This chapter describes the different design steps needed to go from legacy code to a transformed application that can be efficiently mapped on the hArtes platform
Scilab/Scicos: an Open Source Platform for Embedded Real Time Systems Development
International audienceComplex, heterogeneous, real time embedded applications require sophisticated developments tools for simulation and implementation. Commercial, closed source applications are available “on the shelf”, but the associated financial effort and the limited flexibility are not always compatible with the budget constraints and the technical specifications. Some specific requirements of the embedded applications match very well the intrinsic proprieties of the Open Source software. In this paper we show how Scilab/Scicos can play the role of an Open Source platform for embedded systems by presenting both its development model and its applications
Software tools for real-time simulation and control
The objective of this thesis is to design and simulate a multi-agent based energy management system for a shipboard power system in hard real-time environment. The automatic reconfiguration of shipboard power systems is essential to improve survivability. Multi-agent technology is used in designing the reconfigurable energy management system using a self-stabilizing maximum flow algorithm. The agent based energy management system is designed in a Matlab/Simulink environment. Reconfiguration is performed for several situations including start-up, loss of an agent, limited available power, and distribution to priority ranked loads. The number of steps taken to reach the global solution and the time taken are very promising. With the growing importance of timing accuracy in simulating control systems during design and development, there is an increased need for these simulations to run in a real-time environment. This research further focuses on software tools that support hard real-time environment to run real-time simulations. A detailed survey has been conducted on freely available real-time operating systems and other software tools to setup a desktop PC supporting real-time environment. Matlab/Simulink/RTW-RTAI was selected as real-time computer aided control design software for demonstrating real-time simulation of agent based energy management system. The timing accuracy of these simulations has been verified successfully
hArtes: Hardware-Software Codesign for Heterogeneous Multicore Platforms
Developing heterogeneous multicore platforms requires choosing the best hardware configuration for mapping the application, and modifying that application so that different parts execute on the most appropriate hardware component. The hArtes toolchain provides the option of automatic or semi-automatic support for this mapping. During test and validation on several computation-intensive applications, hArtes achieved substantial speedups and drastically reduced development times

TANGO: Transparent heterogeneous hardware Architecture deployment for eNergy Gain in Operation
The paper is concerned with the issue of how software systems actually use
Heterogeneous Parallel Architectures (HPAs), with the goal of optimizing power
consumption on these resources. It argues the need for novel methods and tools
to support software developers aiming to optimise power consumption resulting
from designing, developing, deploying and running software on HPAs, while
maintaining other quality aspects of software to adequate and agreed levels. To
do so, a reference architecture to support energy efficiency at application
construction, deployment, and operation is discussed, as well as its
implementation and evaluation plans.Comment: Part of the Program Transformation for Programmability in
