This paper presents a novel hardware framework of particle swarm optimization (PSO) for various kinds of discrete optimization problems based on the system-on-a-programmable-chip (SOPC) concept. PSO is a new optimization algorithm with a growing field of applications. Nevertheless, similar to the other evolutionary algorithms, PSO is generally a computationally intensive method which suffers fr...

This paper presents a SoPC (System-ona-Programmable-Chip) embedded system featuring selfreconfigurable capability. It addresses the factors that limit the system performance when FPGAs are used to implement various encryption algorithms dynamically. The limiting factors are the data transfer rate between the host and the FPGA, and the reconfiguration latency. The results generated by the crypto...

Le développement et la diffusion des équipements TEP passent par la réduction des temps de calcul de la reconstruction des images acquises. Aussi cet article présente une solution mixte logicielle/matérielle pour l’accélération de la reconstruction 2D sur une plateforme SOPC (System On Programmable Chip), la nouvelle génération de circuits reconfigurables. L’architecture présentée permet de rés...

For the past several decades, designers have processed speech for a wide variety of applications ranging from mobile communications to automatic reading machines. Speech recognition reduces the overhead caused by alternate communication methods. Speech has not been used much in the field of electronics and computers due to the complexity and variety of speech signals and sounds. However, with m...
