This paper proposes a reconfigurable architecture for the implementation of real-time vision systems on FPGA. The architecture is composed of a library of components that can be used to perform several image processing and vision tasks. Components can be organized in one or more processing pipelines. A full frame or part of the frame can be buffered during the process to allow region-based operations...
This paper outlines a scheduling methodology for signal processing applications onto heterogeneous multiprocessor systems. The goal is to efficiently schedule an application in the form of direct acyclic graphs (DAG), onto a heterogeneous processor environment. The solution is to use a variety of optimization techniques based on greedy methods and meta-heuristic methods to solve the problem. Results...
The advance in FPGA technology allowed embedding different types of resources on a single chip. These resources range from a simple look-up table to a complete processor. The resources available on the FPGA fabric allow building various hardware systems for different applications with several trade-offs in terms of performance and power consumption. This paper proposes six different architectures...
Advances in chip technology have enabled integrating many functional units on a single chip. This led to the emergence of the concept of system-on-chip (SoC) which is used extensively in the development of advanced embedded systems. Embedded systems are widely used today in different digital signal processing (DSP) applications that usually require high computation power and tight constraints. Using...
Résumé: Les auteurs rapportent l’observation d’une femme tunisienne âgée de 50 ans, nullipare et ménopausée depuis 10 ans, qui consultait pour des métrorragies. L’examen clinique révélait une masse bourgeonnante du col utérin de 2,5 cm de grand axe dont la biopsie avait montré une prolifération tumorale maligne faite de petites cellules rondes. L’étude immunohistochimique a retenu le diagnostic de...
