چکیده
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 résoudre élégamment le verrou posé par la latence des accès mémoire grâce au cache 2D Adaptatif et Prédictif, tout en proposant un système souple d’utilisation.

Design and Implementation of SoPC with Multi-Bus on a Chip
SoPC (System on a Programmable Chip) is one important kind of SoC solution based on PLD (Programmable Logic Device). At the same time, PBD (Platform-based Design) has become popular and hot on the SoPC design. However, single-bus architecture has been widely adopted in the design of SoPC using PBD. Therefore, many applications, especially those for real-time data processing, suffer from the bot...
متن کاملDevelopment of SCAR Markers for the Identification of Phytophthora katsurae Causing Chestnut Ink Disease in Korea
Sequence characterized amplified region (SCAR) markers are one of the most effective and accurate tools for microbial identification. In this study, we applied SCAR markers for the rapid and accurate detection of Phytophthora katsurae, the casual agent of chestnut ink disease in Korea. In this study, we developed seven SCAR markers specific to P. katsurae using random amplified polymorphic DNA ...
متن کامل3-D Camera SoPC Design Architecture
It is often seen that the available knowledge base within an organisation influences the selection of the design platform. The two major contenders for signal processing hardware platforms are DSP processor and FPGA. DSP processor offers high compute intensive complete embedded product where as FPGA offers high flexibility to a System on Programmable Chip (SoPC) designer for proof of concept at...
متن کاملDesign and Implementation of DCT Accelerators in SOPC-based Embedded System for Digital Color Image Watermarking
digital watermarking techniques have been exploited to protect the copyright of multimedia data in the emerging systems. In this paper, an efficient watermarking approach for System-on-Programmable-Chip (SOPC) realization is proposed. We analyzed the software efficiency of watermark embedding with Nios-II soft-CPU and proposed a cost-effective architecture for the design of Discrete Cosine Tran...
متن کاملCRAC motif peptide of the HIV-1 gp41 protein thins SOPC membranes and interacts with cholesterol.
This study uses low-angle (LAXS) and wide-angle (WAXS) X-ray synchrotron scattering, volume measurements and thin layer chromatography to determine the structure and interactions of SOPC, SOPC/cholesterol mixtures, SOPC/peptide and SOPC/cholesterol/peptide mixtures. N-acetyl-LWYIK-amide (LWYIK) represents the naturally-occurring CRAC motif segment in the pretransmembrane region of the gp41 prot...
