This paper considers an ATDM system with an in nite bu er and a nite number of identical users, generating data only during their active period. This work di ers from most prior studies of ADTM systems in that a user is here allowed to remain active without sending data packets: this behaviour is called spacing . Assuming geometric distribution for the active and the passive period and for the ...

In this paper the efficacy of this approach is studied for the implementation on FPGA. For this study, both non pipelined and 2 level pipelined CORDIC with 8 stages and using two schemes – one using adders in all the stages and another using multiplexers in the second and third stages. A 16 bit CORDIC for generating the sine/cosine functions is implemented using all the four schemes on both Xil...

The control of source-coded traac at a multiplexer has been a topic of extensive research. Traditional approaches typically use feedback information on the buuer level in designing the control policy. While important , buuer levels capture only part of the information about the overall system state. By setting up this problem as a Markov decision process, we show that using information on the s...

Among emerging technologies, Quantum-dot Cellular Automata (QCA) is an attractive alternative for transistor based technologies. In this paper, novel efficient Quantum-dot Cellular Automata (QCA) devices are proposed that provide 3-input and 4-input AND & OR gates. These gates have simple structure and are efficient in term of cell counts, complexity and latency. These components are suitable f...

In this paper we propose analytical models for estimating the leakage power in CMOS based SRAM designs. We identify the transistors that contribute to the leakage power in each SRAM sub-circuit as a function of the operation (read/write/idle) on the SRAM and develop parameterized leakage power models in terms of the high level design parameters and transistor widths. The models take number of r...

This paper studies the impact of long-range-dependent (LRD) traffic on the performance of a network multiplexer. The network multiplexer is characterized by a multiplexing queue with a finite buffer and an M/G/∞ input process. Our analysis expresses the loss probability bounds using a simple relationship between loss probability and buffer full probability. Our analysis also derives an exact ex...

For a family of arrival processes A ; > 0, we give suucient conditions under which the queue length distribution satisses lim !0 lim x!1 ? log IPPQ x]=x= ; for some > 0 called the asymptotic decay rate. Using this result we show, under strict stability conditions , that the asymptotic decay rate of an ATM network multiplexer does not depend on the slow time scale statistics. However, the rate a...

This paper presents a new design for 14 transistor single bit full adder, implemented using five transistor XNOR/XOR cell and transmission gate multiplexer. For transmission gate multiplexer complementary gate control signals are required and in 14 transistor full Adder both XOR and XNOR signals are generated. XNOR/XOR cell shows high power consumption than single XNOR gate. So, 8 transistor fu...
