Abstract:
Interconnections are increasingly the dominant contributor to delay, area and energy consumption in CMOS digital circuits. The proposed implementation overcomes several limitations found in previous quaternary implementations published so far, such as the need for special features in the CMOS process or power-hungry current-mode cells. We have to use the 512bit quaternary Look Up Table for high level of operations in the FPGA.The proposed architecture of this paper will be planned to implemented and also analysis the output current, output voltage, area using Xilinx 14.3.

Abstract: This paper proposes efficient constant multiplier architecture based on vertical-horizontal binary common sub-expression elimination (VHBCSE) algorithm for designing a reconfigurable finite impulse response (FIR) filter whose coefficients can dynamically change in real time. To design an efficient reconfigurable FIR filter, according to the proposed VHBCSE algorithm, 2-bit binary common sub-expression elimination (BCSE) algorithm has been applied vertically across adjacent coefficients on the 2-D space of the coefficient matrix initially, followed by applying variable-bit BCSE algorithm horizontally within each coefficient. Faithfully rounded truncated multiple constant multiplication/accumulation (MCMAT) and multi-root binary partition graph (MBPG) respectively. Efficiency shown by the results of comparing the FPGA and ASIC implementations of the reconfigurable FIR filter designed using VHBCSE algorithm based constant multiplier establishes the suitability of the proposed algorithm for efficient fixed point reconfigurable FIR filter synthesis.

Abstract: This paper proposes a simple and efficient Montgomery multiplication algorithm such that the low-costand high-performance Montgomery modular multiplier can be implemented accordingly. The proposed multiplier output data with representation and uses only one parallel prefix adder to avoid a carry propagation and reduce the area, power and delay, and also increasing the speed. Mainly the usage of parallel prefix adder is to reduce the significant delay reduction and area × time2 improvements, all this at the cost of higher power consumption, which is the main reason preventing the use of parallel-prefix adders to achieve high-speed reverse converters in nowadays systems. Hence, to solve the high power consumption problem, novel specific hybrid parallel-prefix-based adder components those provide better trade-off between delay and power consumption. As a result, the extra clock cycles for operand pre-computation and format conversion can be hidden and high throughput can be obtained. Experimental results show that the proposed Montgomery modular multiplier can achieve higher performance and significant area–time product improvement when compared with previous designs. Using VHDL to design the RTL, and the result to be shown in Xilinx 14.2 with Power consumption and area reduction.

Abstract:
In this brief, a low-cost low-power all-digital spread spectrum clock generator (ADSSCG) is presented. The proposed ADSSCG can provide an accurate programmable spreading ratio with process, voltage, and temperature variations. To maintain the frequency stability while performing triangular modulation, the fast-relocked mechanism is proposed. The proposed fast-relocked ADSSCG is implemented in a standard performance 90-nm CMOS process, and the active area is 200 µm × 200 µm. The experimental results show that the electromagnetic interference reduction is 14.61 dB with a 0.5% spreading ratio and 19.69 dB with a 2% spreading ratio at 270 MHz The power consumption is 443 µW at 270 MHz with a 1.0 V power supply.

This paper presents a novel approach to design obfuscated circuits for digital signal processing (DSP) applications using high-level transformations, a key-based obfuscating finite-state machine (FSM), and a reconfigurator. The goal is to design DSP circuits that are harder to reverse engineer. High level transformations of iterative data-flow graphs have been exploited for area-speed-power tradeoffs. This is the first attempt to develop a design flow to apply high level transformations that not only meet these tradeoffs but also simultaneously obfuscate the architectures both structurally and functionally. Functional obfuscation is accomplished by requiring use of the correct initialization key, and configure data. Structural obfuscation is also achieved by the proposed methodology via high-level transformations. The proposed architecture of this paper analysis the logic size, area and power consumption using Xilinx 14.2

A multiplier is one of the key hardware blocks in most digital and high performance systems such as FIR filters, micro processors and digital signal processors etc. A system’s performance is generally determined by the performance of the multiplier because the multiplier is generally the slowest element in the whole system and also it is occupying more area consuming. The Carry Select Adder (CSLA) provides a good compromise between cost and performance in carry propagation adder design. A Square Root Carry Select Adder using RCA is introduced but it offers some speed penalty. However, conventional CSLA is still area-consuming due to the dual ripple carry adder structure. In the proposed work, generally in Wallace multiplier the partial products are reduced as soon as possible and the final carry propagation path carry select adder is used. In this paper, modification is done at gate level to reduce area and power consumption. The Modified Square Root Carry Select-Adder (MCSLA) is designed using Common Boolean Logic and then compared with regular CSLA respective architectures, and this MCSLA is implemented in Wallace Tree Multiplier. This work gives the reduced area compared to normal Wallace tree multiplier. Finally an area efficient Wallace tree multiplier is designed using common Boolean logic based square root carry select adder.
