A TCB and security kernel architecture for supporting multi-threaded, queue-driven transaction processing applications in a multilevel secure environment is presented. Our design exploits hardware security features of the Intel 80x86 processor family. Intel’s CPU architecture provides hardware with two distinct descriptor tables. We use one of these in the usual way for process isolation. For e...

A simulation framework for articial neural network models and electronic implementations (CMOS) is presented. Neural network models spanning from arti-cial biological models through mathematical or computational models such as back-propagation type networks to digital, analog or subthreshold analog implementations can be simulated concurrently. Neural and electronic variables (nodes) interact t...

the large amount of computation necessary for obtaining time optimal solution for moving a manipulator on specified path has made it impossible to introduce an on line time optimal control algorithm. most of this computational burden is due to calculation of switching points. in this paper a learning algorithm is proposed for finding the switching points. the method, which can be used for both ...

one of the most controversial and unresolved questions in bilingual first language acquisition (henceforth bfla) is whether bilingual children develop one mixed or two independent linguistic systems. many scholars in the lield of bfla arc in tavor of the one-system hypothesis (leopold 1970; swain and wesche, 1975; volterra and tacschner, j 987; grosjean, 1982; tacschncr, 1983: mclaughlin, 1984:...

Routers and Switches are key building blocks of global networks. Data rates in the range of multiple gigabit per second are owing trough them and emerging router functionalities (active networking, layer 4 switching,. . .) require fast and eecient routers. Therefore, hardware support is needed in order to speed up the performance critical forwarding task. This paper presents a exible hardware s...

A neural network based implementation of space vector modulation of a voltage-sourced inverter has been proposed in this paper. Use of ANN based technique avoids the direct computation of trigonometric function (e. g. sine function) as in conventional space vector modulation implementation. The main disadvantages with conventional implementation are, use of any look-up table implies the need fo...

In this paper, a high-performance all-digital quadrature frequency synthesizer/mixer applied to QAM modulation and demodulation is presented, which synthesizes 12-bit sine and cosine waveforms with a spectral purity of –83.0dB. The synthesizer covers a bandwidth from dc to 100 MHz in steps of 0.0466Hz with a corresponding switching speed of 5 ns at 200MHz clock frequency. Also, it is capable of...

This paper aims at implementation of a low power adaptive FIR filter based on distributed arithmetic (DA) with low power, high throughput, and low area. Least Mean Square (LMS) Algorithm is used to update the weight and decrease the mean square error between the current filter output and the desired response. The pipelined Distributed Arithmetic table reduces switching activity and hence it red...
