This paper presents the implementation of curve on FPGA circuit (Field Programmable Gate Array) Spartan 3 of Xilinx, it based on Taylor approximation by segment, used third order polynomial in order to reduce the maximum error. First of all, we have stocked all coefficients, computing with Mat lab tool, in the block memory. After that, an architecture is proposed and implemented under ISE9.2i environment...
In this paper, we propose a hardware implementation of a Feed-Back Chaotic Synchronization (FCS) for designing a real-time secure symmetric encryption scheme. This proposed scheme allows for the design and implementation of real time synchronization between two embedded chaotic generators for secure communications. The implementation and experimental results mapped on two Xilinx FPGA Virtex technology...
This paper describes a Field Programmable Gate Array (FPGA) implementation of a Digital Front End (DFE) block for a Multi-Carrier Multi-Antenna (MCMA) system. The decimation/ interpolation filters used for obtaining the required channel bandwidth are split into several low order decimation/ interpolation stages, each of them being implemented as a polyphase filter. At the receiver, the DFE contains...
Due to aggressive technology scaling VLSI circuits have become more susceptible to transient errors. The associated reduction in supply voltages has decreased noise margins, causing system reliability to be reduced increasingly at a time when electronic systems are being used in ldquosafety criticalrdquo applications. Clock distribution issues as well as the demands for low power circuits have exposed...
