This paper presents an approach based on hardware/software partitioning to minimize the logic area of System on a Programmable Chip (SOPC) while respecting a time constraint. Our contribution focuses on introducing a new hardware/software partitioning algorithm. This algorithm is based on the principle of Binary Search Trees (BST) and genetic algorithms. It aims to define the tasks that will ru...

In the inverter circuit, there exists a specific on-off time in each power transistor. As such, to prevent short circuit of two switch devices on upper and lower bridge arms, dead must be set pulse width modulation (PWM) sinusoidal (SPWM) signals. this paper, an intellectual property (IP) core that can introduce high-precision arbitrary length into PWM or SPWM signals is designed increase preci...

The number of resources available in largest reconfigurable devices enables the synthesis of systems with more than 100 Soft-Core processors. Although being a feasible and attainable alternative, few such systems have been built and few works propose methods to create, program and optimize this kind of systems. In this work we present a methodology that helps the designer to built MPSoC systems...

This paper presents a novel VLSI architecture for the training of radial basis function (RBF) networks. The architecture contains the circuits for fuzzy C-means (FCM) and the recursive Least Mean Square (LMS) operations. The FCM circuit is designed for the training of centers in the hidden layer of the RBF network. The recursive LMS circuit is adopted for the training of connecting weights in t...

Soft computing techniques are gaining momentum as tools for network traffic modeling, analysis and control. Efficient hardware implementations of these techniques that can achieve real-time operation in high-speed communications equipment is however an open problem. This paper describes a platform for the development of fuzzy systems with applications to communications systems, namely network t...

Solving Linear Equation System (LESs) is a common problem in numerous fields of science. Even though the well studied and powerful solvers are available nowadays, solving LES still bottleneck many numerical applications concerning computation time. This issue especially pertains to mobile robotics constrained by real-time requirements, where on-top power consumption weight play an important rol...

This paper presents our approach of the radio interface problematic for Wireless Sensor Network. We introduce the WSN context and constraints associated. We propose an IR-UWB solution and illustrate why it could be a viable solution for WSN. A high level modelling and simulation platform for IR-UWB radio interface is proposed on Matlab. It allows us to determine according to BER versus Eb/N0 cr...

Robotic control is currently an exciting and highly challenging research focus. Several solutions for implementing the control architecture for robots have been proposed (Kabuka et al., 1988; Yasuda, 2000; Li et al., 2003; Oh et al., 2003). Kabuka et al. (1998) apply two highperformance floating-point signal processors and a set of dedicated motion controllers to build a control system for a si...
