This paper concerns with automatic pipeline implementation of a program subject to some real time (RT) constraints; the program is described through a Control Data Flow Graph (CDFG). We have developed a mapping methodology which assigns to each instruction of CDFG a time step and a HW resource for its execution. We have defined the space Ω of all the(More)
In recent years Image Fractal Compression techniques (IFS) have gained more interest because of their capability to achieve high compression ratios while maintaining very good quality of the reconstructed image. The main drawback of such techniques is the very high computing time needed to determine the compressed code. In this work, after a brief(More)
Starting from a mathematical reinterpretation of the classical crossover operator, a new type of crossover is introduced. The proposed new crossover operator gives better performances than the classical 1 point, 2 point or uniform crossover operators. In the paper a theorical investigation of the behaviour of the new crossover is presented. In comparison to(More)
In the last years, since the early 80's, wormhole and virtual cut-through routing modalities have replaced packet switching and circuit switching schemes. In this paper we give the theoretical bases to implement hole based (HB) routing algorithm [3] by using the virtual cut-through modality. After reviewing the theory of HB routing, we demonstrate some(More)
