Area–Delay–Power Efficient Carry-Select
Adder
Abstract—In this brief, the logic operations involved in conventional carry select
adder (CSLA) and binary to excess-1 converter (BEC)-based CSLA are analyzed
to study the data dependence and to identify redundant logic operations. We have
eliminated all the redundant logic operations present in the conventional CSLA and
proposed a new logic formulation for CSLA. In the proposed scheme, the carry
select (CS) operation is scheduled before the calculation of final-sum, which is
different from the conventional approach. Bit patterns of two anticipating carry
words (corresponding to cin = 0 and 1) and fixed cin bits are used for logic
optimization of CS and generation units. An efficient CSLA design is obtained
using optimized logic units. The proposed CSLA design involves significantly less
area and delay than the recently proposed BEC-based CSLA. Due to the small
carry-output delay, the proposed CSLA design is a good candidate for square-root
(SQRT) CSLA. A theoretical estimate shows that the proposed SQRT-CSLA
involves nearly 35% less area–delay–product (ADP) than the BEC-based SQRT-
CSLA, which is best among the existing SQRT-CSLA designs, on average, for
different bit-widths. The application-specified integrated circuit (ASIC) synthesis
result shows that the BEC-based SQRT-CSLA design involves 48% more ADP
and consumes 50% more energy than the proposed SQRT-CSLA, on average, for
different bit-widths.

Abstract: In VLSI Technology, Carry Propagation Delay is the most important concern for the Adders. Adder is the most unavoidable component for the arithmetic performances. This paper is Modified Square Root-Carry Select Adder (SQRT-CSLA) design reduces the delay with 16 bit adder. Carry select adder have two units for Carry Generation (CG) and Carry Selection (CS). The modified SQRT-CSLA design can gives parallel path for carry propagation. So the overall adder delay has reduced. Modified design is obtained using Ripple Carry Adder (RCA) with Boolean Excess-1 Converter (BEC). BEC produces an output i.e., is an excess one result for given input bits. Then input bits and BEC output is given to multiplexer for carry selection. Use of BEC instead of dual RCA gives efficient carry propagation delay and it consumes the lower power and overall gates using in design is reduced with compared to carry select adder with dual RCA. The final sum is calculated using final sum generation.

Design and Implementation of Low-Power and Area-Efficient 64 bit CSLA using VHDL

IJSRD

All processor consisting ALU and adder plays important role for design of ALU. Design of low area and power efficient adder helps to reduce power consumption and area of any processor. Now a dayÃ¢â‚¬â„¢s major area of research in VLSI system is design of area, high speed and low power data path logic systems. In digital adders, the speed of addition is restricted by the time necessary to send a carry signal through the adder. The area and power consumption is reduced by modifying regular CSLA architecture. The proposed architecture is developed with the help of a simple ripple carry adder (RCA) and gate-level architecture. It consists of single RCA which improves the performance of the proposed designs then the regular designs in terms of power consumption and area.

Abstract: In the design of Integrated circuit area occupancy plays a vital role because of increasing the necessity of portable systems. Carry Select Adder (CSLA) is a fast adder used in data processing processors for performing fast arithmetic functions. From the structure of the CSLA, the scope is reducing the area of CSLA based on the efficient gate-level modification. In this paper 16 bit, 32 bit, 64 bit and 128 bit Regular Linear CSLA, Modified Linear CSLA, Regular Square-root CSLA (SQRT CSLA) and Modified SQRT CSLA architectures have been developed and compared. However, the Regular CSLA is still area-consuming due to the dual Ripple-Carry Adder (RCA) structure. For reducing area, the CSLA can be implemented by using a single RCA and an add-one circuit instead of using dual RCA. Comparing the Regular Linear CSLA with Regular SQRT CSLA, the Regular SQRT CSLA has reduced area as well as comparing the Modified Linear CSLA with Modified SQRT CSLA; the Modified SQRT CSLA has reduced area. The results and analysis show that the Modified Linear CSLA and Modified SQRT CSLA provide better outcomes than the Regular Linear CSLA and Regular SQRT CSLA respectively. This project was aimed for implementing high performance optimized FPGA architecture. Modelsim 10.0c is used for simulating the CSLA and synthesized using Xilinx PlanAhead13.4. Then the implementation is done in Virtex5 FPGA Kit. Keywords: Field Programmable Gate Array (FPGA), efficient, Carry Select Adder (CSLA), Square-root CSLA (SQRTCSLA).

This paper presents a recursive designing approach for high energy efficient carry select adder (CSA). Nowadays, the portable equipment’s like mobile phones and laptops have higher demands in the market. So, the designers must focus greater attention while designing such devices. Which means that have the devices must have lesser power consumption, low cost and have a better performance. The customers mainly focus on the equipment’s which have lesser power consumption, low cost and better performance. As we all know that the adders are the basic building block of microprocessors. The performance of the adders greatly influences the performance of those processors. The carry select adder is most suitable among other adders which have fast addition operation at low cost. The carry select adder (CSA) consists of chain full adders (FAs) and multiplexers. Here a carry select adder is designed with four FAs and four multiplexers. The proposed structure is assessed by the power consumption of the carry select adder using a 32-nm static CMOS technology for a wide range of supply voltages. The simulation results are obtained using Tanner EDA which reveals that the carry select adder has low power consumption.

CPUs in general-purpose personal computers, such as desktops and laptops, dissipate significantly more power in the order of few watts because of their higher complexity and speed. ALU is a fundamental building block of CPU. It does all process related to arithmetic and logic operations. As the operations become more complex, the ALU become more complex, more expensive, takes up more space in the CPU and contributes more power dissipation within the CPU. Hence power consumption of ALU is a major issue in the designing of CPU.

FPGA Implementation of High Speed Architecture of CSLA using D-Latches

Editor IJMTER

Carry Select Adder (CSLA) is one of the fastest adders used in many data-processing processors to perform fast arithmetic functions. The CSLA is used in many systems to overcome the problem of carry propagation delay by independently generating multiple carries and then select a carry to generate the sum. But the CSLA is not area efficient because it uses multiple pairs of Ripple Carry Adders (RCA). Due to the rapidly growing mobile industry not only the faster arithmetic unit but also less area and low power arithmetic units are needed. The modified CSLA architecture has developed using Binary to Excess-1 converter (BEC). This paper proposes an efficient method which replaces the BEC using D latch. Designs were developed using structural VHDL and synthesized in Xilinx 13.2 with reference to FPGA device XC3S500E.

IJERA Editor

The addition of two binary numbers is the important and most frequently used arithmetic process on microprocessors, digital signal processors (DSP), and data-processing application-specific integrated circuits (ASIC). Therefore, binary adders are critical structure blocks in very large-scale integrated (VLSI) circuits. Their effective application is not trivial because a costly carry spread operation involving all operand bits has to be achieved. Many different circuit constructions for binary addition have been planned over the last decades, covering a wide range of presentation characteristics. In today era, reversibility has become essential part of digital world to make digital circuits more efficient. In this paper, we have proposed a new method to reduce quantum cost for ripple carry adder and carry skip adder. The results are simulated in Xilinx by using VHDL language.

128-Bit Area Efficient Reconfigurable Carry Select Adder

ijcisjournal

Adders are one of the most critical arithmetic circuits in a system and their throughput affects the overall performance of the system. Carry Select Adder (CSLA) is one of the fastest adders used in many dataprocessing processors to perform fast arithmetic functions. From the structure of the CSLA, it is clear that there is scope for reducing the area and power consumption in the CSLA. In this paper, we proposed an area-efficient carry select adder by sharing the common Boolean logic term. After logic optimization and sharing partial circuit, we only need one XOR gate and one inverter gate for sum generation. Through the multiplexer, we can select the final-sum only and for carry selection we need only one AND gate and one OR gate. Based on this modification 16-, 32-, 64-, and 128-bit CSLA architecture have been developed and compared with the conventional CSLA architecture. The proposed design greatly reduces the area compared to other CSLAs. From this improvement, the gate count of a 128-bit carry select adder can be reduced from 3320 to 1664. The proposed structure is implemented in Artix-7 FPGA. Compared with the proposed design, the conventional CSLA has 65.80% less area.

Area-Delay Efficient Binary Adders in QCA

IJERA Editor

In this paper, a novel quantum-dot cellular automata (QCA) adder design is presented that decrease the number of QCA cells compared to previously method designs. The proposed one-bit QCA adder is based on a new algorithm that requires only three majority gates and two inverters for the QCA addition. A novel 128-bit adder designed in QCA was implemented. It achieved speed performances higher than all the existing. QCA adders, with an area requirement comparable with the low RCA and CFA established. The novel adder operates in the RCA functional, but it could propagate a carry signal through a number of cascaded MGs significantly lower than conventional RCA adders. In adding together, because of the adopted basic logic and layout strategy, the number of clock cycles required for completing the explanation was limited. As transistors reduce in size more and more of them can be accommodated in a single die, thus increasing chip computational capabilities. However, transistors cannot find much smaller than their current size. The quantum-dot cellular automata approach represents one of the possible solutions in overcome this physical limit, even though the design of logic modules in QCA is not forever straightforward.

VIT-AP University

The CMOS-based integrated circuit may scale down to nanometer range. The primary challenge is to further downscale the device and high-energy dissipation. Reversible logic does not dissipate energy and no information loss. In this way, the state-of-the-art technology such as QCA was forced toward high-speed computing with negligible energy dissipation in the physical foreground. This work targets the design of non-restoring reversible divider circuit and its implementation in QCA. We have utilized few 2 × 2 FG and 4 × 4 HNG gates as the block construction and also show the QCA implementation having cost-efficient approach. Further, the divider circuit has synthesized with FG and HNG gates and QCA implementation. This divider circuit inherits many benefits such as fewer garbage outputs, reduce quantum cost are achieved, and also reduced QCA primitives can be improved by using efficient QCA layout scheme. Simulation investigations have been verified by QCA Designer. The proposed non-restoring divider also compares the reversible metrics results with some of other existing works.

Regular clocking scheme based design of cost-efficient comparator in QCA

nooriasukmaningtyas

Quantum-dot cellular automata (QCA) gained a notable attraction in the emerging nanotechnology to get the better of power consumption, density, nano-scale design, the performance of the present CMOS technology. Many designs had been proposed in QCA for an arithmetic circuit like adder, divider, parity checker and comparator etc. Most of the designs have been facing the challenges of cost efficiency, power dissi-pation, device density etc. However, consideration of design automation, underlying clocking layout and integration of the sub modules are the most important which has a direct impact on the fabrication of the design. This work proposed a novel cost ef-fective and power aware comparator design, which is an essential segment in central processing unit (CPU). The noticeable novelty of the design was the use of underlying regular clocking scheme. A new scalable, regular clocking scheme has been utilized in the coplanar design of the comparator which enables regular or uniform cell layout of QCA circuit. It also exhibited the significant improvement over existing counterparts having irregular clocking in terms of area and latency. QCADesigner was used to test and verify the functionality of the circuit and by using QCAPro the power dissipation has been analyzed.

LOGIC OPTIMIZATION USING TECHNOLOGY INDEPENDENT MUX BASED ADDERS IN FPGA

VLSICS Design

Adders form an almost obligatory component of every contemporary integrated circuit. The prerequisite of the adder is that it is primarily fast and secondarily efficient in terms of power consumption and chip area. Therefore, careful optimization of the adder is of the greatest importance. This optimization can be attained in two levels; it can be circuit or logic optimization. In circuit optimization the size of transistors are manipulated, where as in logic optimization the Boolean equations are rearranged (or manipulated) to optimize speed, area and power consumption. This paper focuses the optimization of adder through technology independent mapping. The work presents 20 different logical construction of 1-bit adder cell in CMOS logic and its performance is analyzed in terms of transistor count, delay and power dissipation. These performance issues are analyzed through Tanner EDA with TSMC MOSIS 250nm technology. From this analysis the optimized equation is chosen to construct a full adder circuit in terms of multiplexer. This logic optimized multiplexer based adders are incorporated in selected existing adders like ripple carry adder, carry look-ahead adder, carry skip adder, carry select adder, carry increment adder and carry save adder and its performance is analyzed in terms of area (slices used) and maximum combinational path delay as a function of size. The target FPGA device chosen for the implementation of these adders was Xilinx ISE 12.1 Spartan3E XC3S500-5FG320. Each adder type was implemented with bit sizes of: 8, 16, 32, 64 bits. This variety of sizes will provide with more insight about the performance of each adder in terms of area and delay as a function of size.

Novel Tree Structure Based Conservative Reversible Binary Coded Decimal Adder...

VIT-AP University

Reversible logic has been recognized as one of the most promising technique for the realization of the quantum circuit. In this paper, a cost effective conservative, reversible binary coded decimal (BCD) adder is proposed for the quantum logic circuit. Towards the realization of BCD adder, few novel gates, such as Half-Adder/Subtraction (HAS-PP), Full-Adder/Subtraction (FAS-PP) and Overflow-detection (OD-PP) based on parity preserving logic are synthesized which incurs 7, 10 and 13 quantum cost respectively. Coupling these gates a novel tree-based methodology is proposed to implement the required BCD Adder. Also, the BCD adder design has been optimized to achieve the optimum value of quantum cost. In addition, the proposed BCD circuit is extended to n-bit adder using replica based techniques. Experimental result establishes the novelty of the proposed logic, which outperforms the conventional circuits in terms of logic synthesis and testability. The limitation of detecting the missing gate and missing control point of the quantum circuit of overflow detection is finally tackled this work by the proposed OD-PP with the application of the minimum test vector. In addition, reversible circuits of control inputs based testable master-slave D-FF is intended. The noted work on the testable sequential circuit presented here is to develop circuit using minimum test vectors and can find diverse application in the testing paradigm

gerogepatton

This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks (CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations. When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10 and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing accuracy improvements over previous techniques. The results indicate that the combination of the volumetric input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating adversary training.

Power plants release a large amount of water vapor into the atmosphere through the stack. The flue gas can be a potential source for obtaining much needed cooling water for a power plant. If a power plant could recover and reuse a portion of this moisture, it could reduce its total cooling water intake requirement. One of the most practical way to recover water from flue gas is to use a condensing heat exchanger. The power plant could also recover latent heat due to condensation as well as sensible heat due to lowering the flue gas exit temperature. Additionally, harmful acids released from the stack can be reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation. Condensation of vapors in flue gas is a complicated phenomenon since heat and mass transfer of water vapor and various acids simultaneously occur in the presence of noncondensable gases such as nitrogen and oxygen. Design of a condenser depends on the knowledge and understanding of the heat and mass transfer processes. A computer program for numerical simulations of water (H2O) and sulfuric acid (H2SO4) condensation in a flue gas condensing heat exchanger was developed using MATLAB. Governing equations based on mass and energy balances for the system were derived to predict variables such as flue gas exit temperature, cooling water outlet temperature, mole fraction and condensation rates of water and sulfuric acid vapors. The equations were solved using an iterative solution technique with calculations of heat and mass transfer coefficients and physical properties.

Area–delay–power efficient carry select adder

1. Logic Mind Technologies Vijayangar (Near Maruthi Medicals), Bangalore-40 Ph: 8123668124 // 8123668066 Area–Delay–Power Efficient Carry-Select Adder Abstract—In this brief, the logic operations involved in conventional carry select adder (CSLA) and binary to excess-1 converter (BEC)-based CSLA are analyzed to study the data dependence and to identify redundant logic operations. We have eliminated all the redundant logic operations present in the conventional CSLA and proposed a new logic formulation for CSLA. In the proposed scheme, the carry select (CS) operation is scheduled before the calculation of final-sum, which is different from the conventional approach. Bit patterns of two anticipating carry words (corresponding to cin = 0 and 1) and fixed cin bits are used for logic optimization of CS and generation units. An efficient CSLA design is obtained using optimized logic units. The proposed CSLA design involves significantly less area and delay than the recently proposed BEC-based CSLA. Due to the small carry-output delay, the proposed CSLA design is a good candidate for square-root (SQRT) CSLA. A theoretical estimate shows that the proposed SQRT-CSLA involves nearly 35% less area–delay–product (ADP) than the BEC-based SQRT- CSLA, which is best among the existing SQRT-CSLA designs, on average, for different bit-widths. The application-specified integrated circuit (ASIC) synthesis result shows that the BEC-based SQRT-CSLA design involves 48% more ADP and consumes 50% more energy than the proposed SQRT-CSLA, on average, for different bit-widths.
