In this paper, we present a new network-on-chip (NoC) that handles accurate localizations of the faulty parts of the NoC. The proposed NoC is based on new error detection mechanisms suitable for dynamic NoCs, where the number and position of processor elements or faulty blocks vary during runtime. Indeed, we propose online detection of data packet and(More)
Image analysis in cancer pathology applications has evolved considerably in the last years [1]. The areas concerned were particularly those in which the diagnosis was based on the medical image processing and analysis. Few studies have successfully investigated the automatic classification of colonic pathology images if they contain healthy cells or(More)
This paper proposes a new Cryptosystem for encryption of the real-time embedded applications. The proposed hardware architecture is based on a chaotic rule switching of several three-dimensional continuous chaotic data generators. The originality of the proposed approach is a new stream chaotic key generator used for real time data encrypt and decrypt. Our(More)
In this paper, a new approach to real-time FPGA implementation of chaotic generator of the random key based Lü's chaotic generator for data stream encryption is presented. We propose a structural hardware architecture designed for a small chip area and high speed performance. This architecture is particularly attractive since it provides a low-cost(More)
In this paper, we present a new reliable and dynamic NoC-based communication approach called RCuNoC designed for the FPGA-based reconfigurable systems. The originality of the RCu routers are the online capacity to detect data packet errors and localize if the errors come from input ports or inside of the routers while distinguish between temporary and(More)
The flexibly of the multiuser detection in wireless receivers is an important consideration for communication system. But with the increasing number of customers, the receiver architecture in the base stations transceiver should also be configurable according to the number of users and channels per user. Hence, the receiver architecture should be able to(More)
In this paper, we present a new approach for realtime FPGA implementation of the random key based Lorenz's chaotic generator for data stream encryption. We propose a structural hardware architecture designed for a small chip area and high speed performance. This architecture is particularly attractive since it provides a low-cost security telecommunication(More)
Digital Video Broadcasting-Handheld (DVB-H) and Terrestrial Digital Multimedia Broadcasting (T-DMB) are the most known standards that enable digital television transmissions to handheld or mobile receivers in Europe. The emerging DVB-T2 standard enables a network based on frequency diversity coding (called Alamouti Space-Frequency coding) suitable for(More)
The automatic recognition and classification of biomedical objects can enhance work efficiency while identifying new inter-relationships among biological features, in this paper Haralick's features based GLCM are applied for classification of cancer cell of textured bio-images. The objective of this work is the selection of the most discriminating(More)
