The evolution of field programmable gate arrays (FPGAs) as custom-computing machines for digital signal processing (DSP), real-time embedded and reconfigurable systems development, embedded processors, and as co-processors for application specific integrated circuit (ASIC) prototyping has led to the emergence of several modeling and design methodologies among which are the register transfer lev...

Spacecraft require all manner of both digital and analog circuits. Onboard digital systems are constructed almost exclusively from field-programmable gate array (FPGA) circuits providing numerous advantages over discrete design including high integration density, high reliability, fast turn-around design cycle time, lower mass, volume, and power consumption, and lower parts acquisition and flig...

Based on the research of MIMO Detection Algorithms theory and implementation methods, here novel k-Best MIMO detection algorithm is presented. Proposed algorithm uses an estimate technique and parallel sort approaches, which reduces the computational difficulty, and adopts pipelined configuration in parallel to save computation time. This algorithm implemented on Xilinx virtex-6. Implementation...

There is great demand today for real-time computer vision systems, with applications including image enhancement, target detection and surveillance, autonomous navigation, and scene reconstruction. These operations generally require extensive computing power; when multiple conventional processors and custom gate arrays are inappropriate, due to either excessive cost or risk, a class of devices ...

The homogeneous structure of field programmable gate arrays (FPGAs) suggests that the defect tolerance can be achieved by shifting the configuration data inside the FPGA. This paper proposes a new approach for tolerating the defects in FPGA’s configurable logic blocks (CLBs). The defects affecting the FPGA’s interconnection resources can also be tolerated with a high probability. This method is...

We present in this paper an acquisition and treatment system designed for semi-analog Gamma-camera. It consists of a nuclear medical Image Acquisition, Treatment and Display chain (IATD) ensuring the acquisition, the treatment of the signals (resulting from the Gamma-camera detection head) and the scintigraphic image construction in real time. This chain is composed by an analog treatment board...

This paper presents a parallel architecture for the solution of linear equations systems based on the Division Free Gaussian Elimination Method. This architecture was implemented in a Field Programmable Gate Array (FPGA). The division-free Gaussian elimination method was integrated in identical processors in a FPGA Spartan 3 of Xilinx. A top-down design was used. The proposed architecture can h...

In recent years there has been great interest in using hybrid spread-spectrum (HSS) techniques for commercial applications, particularly in the Smart Grid, in addition to their inherent uses in military communications. This is because HSS can accommodate high data rates with high link integrity, even in the presence of significant multipath effects and interfering signals. A highly useful form ...

The Swap-Based Tabu Search (SBTS) is a heuristic algorithm for solving the maximum independent set problems and can solve clique as well because in graph equivalent to its complementary graph. Although SBTS powerful has abundant inherent parallelism, it difficult parallelize of solution searching involving indirect indexing on array components. In this paper, we show variant that does not requi...

We also propose the mathematical model new system closed butterfly-like curve By performing bifurcation study system, we analyze intrinsic properties such as chaoticity, multi-stability, and transient chaos. Finally, carry out realization multi-stable using Field-Programmable G...
