Digital Test Signal Generator Implemented with FPGA

In this paper we present a digital generator which produces sine-wave signals with variable frequency. The shape of the signal is stored in memory. The modification of the frequency is achieved by changing the number of samples used to generate a period. The digital circuitry of the generator is implemented using a field programmable gate array (FPGA) and a microcontroller. Experimentally we ha...

Power characterization of digital filters implemented on FPGA

The evaluation of power consumption in complex digital systems is a hard task that normally requires long simulation time and complicated models. In this work, we obtain power consumption estimates from the measurement of the average current absorption of digital filters mapped on a Field Programmable Gate Array (FPGA). We also compare the measurements made with the results previously obtained ...

Power Analysis Of Digital Filters Implemented On FPGAs

The proposed work is to analyze the power consumption of Finite Impulse Response (FIR) filter under different combinatorial modules. Under the considered modules namely Parallel, serial and Distributed Arithmetic(DA) architectures, effects of variation of clock frequency, leakage capacitance, supply voltage are chosen to determine power consumption and junction temperature. Each module is simul...

Digital Signatures: How Close Is Europe to Truly Interoperable Solutions?

Digital signatures have been a hot topic in the e-government era as a key enabler for e-services provided to business and citizens, and secure exchange of e-documents. When this exchange crosses the borders of closed systems or EU’s Member States several interoperability issues arise. In EU many schemes and solutions have been proposed to overcome some problems, yet there is still more to be do...
