Abstract:
The design of fast arithmetic logic circuits is an important research topic for reversible and quantum computing. A special challenge in this setting is the computation of standard arithmetical functions without the generation of garbage. Here, we present a novel parallelization scheme wherein m parallel k-bit reversible ripple-carry adders are combined to form a reversible mk-bit ripple-block carry adder with logic depth [Formula: see text] for a minimal logic depth [Formula: see text], thus improving on the mk-bit ripple-carry adder logic depth [Formula: see text]. The underlying mechanisms of the parallelization scheme are formally proven correct. We also show designs for garbage-less reversible comparison circuits. We compare the circuit costs of the resulting ripple-block carry adder with known optimized reversible ripple-carry adders in measures of circuit delay, width, gate, transistor count, and relative power efficiency, and find that the parallelized adder offers significant speedups at realistic word sizes with modest parallelization overhead.

Abstract:
Very Large-Scale Integration has a greater impact on the developing circuit technology. The Cost and Size has been gradually reducing since years but increased the circuit complexity, there are problems which may affect the growth of VLSI technology. Among them one of major problem is circuit testing. To resolve this issue, we implement Built in Self-Test (BIST). BIST architecture is used to test the circuit itself. Engineers Design BIST to achieve high reliability and low repair cycle times. We implement Linear Feedback Shift Registers (LFSR) to generate the pseudo random test pattern and implement a ripple carry adder as circuit under test and Multiple Input Signature Register(MISR) as output response analyzer and test patterns are given to circuit under test and outputs are obtained these are compared with the actual outputs to test whether the circuit is faulty or not. To check whether the circuit is faulty or fault free we check the obtained outputs with actual outputs using Signature Analysis.

Abstract:

Bit-parallel addition can be performed using a number of adder structures with different area and latency. However, the power consumption of different adder structures is not well studied. Further, the effect of pipelining adders to increase the throughput is not well studied. In this thesis four different adders are described, implemented in VHDL and compared after synthesis. The results give a general idea of the time-delay-power tradeoffs between the adder structures. Pipelining is shown to be a good technique for increasing the circuit speed.

Abstract:

Fast addition is essential in many DSP algorithms. Various structures have been introduced to speed up the time critical carry propagation. For high throughput applications, however, it may be necessary to introduce pipelining. In this report the power consumption of four different adder structures, with varying word length and different number of pipeline cuts, is compared.

Out of the four adder structures compared, the Kogge-Stone parallel prefix adder proves to be the best choice most of the time. The Brent-Kung parallel prefix adder is also a good choice, but the maximal throughput does not reach as high as the maximal throughput of the Kogge-Stone parallel prefix adder.

Adders are fundamental building blocks and often constitute part of the critical path. The maximum operating speed of a Ripple Carry Adder (RCA) is limited by the carry propagation delay, and the penalty of the propagation delay depends on the number of primary input bits. In this paper, we propose four high-speed and compact ripple carry adder designs. The key techniques of these novel designs are race-free dynamic CMOS logic technique for high-speed and compact designs. We demonstrate these designs approach using a 32-bit ripple carry adder built with the TSMC 0.25-um CMOS technology. The adder operates at 2.5V. The SPICE simulation shows that the proposed Dynamic Ripple Carry Adders (DRCAs) are at least 2.38 times faster than the conventional static ripple carry adder (SRCA). Further all of the proposed designs compare much favorably to the previous DRCA design that employs the DCVS logic.

Abstract:
In this chapter, the design and comparative analysis is done in between the most well-known column compression multipliers by Wallace and Dadda in sub-threshold regime. In order to reduce the hardware which ultimately reduces area, power and overall power delay product, an energy efficient basic modules of the multipliers like AND gates, half adders, full adders and partial product generate units have been analyzed for sub-threshold operation. At the last stage ripple carry adder is used in both multipliers. The performance metrics considered for the analysis of the multipliers are: power, delay and PDP. Simulation studies are carried out for 8x8-bit and 16x16-bit input data width. The proposed circuits show energy efficient results with Spectre simulations for the TSMC 180nm CMOS technology at 0.4V supply voltage. The proposed multipliers so implemented outperform its counterparts exhibiting low power consumption and lesser propagation delay as compared to conventional multipliers.
