Variable latency adders have been recently proposed in literature. In variable latency adder unwanted interconnections also reduced compared with kogge-stone topology. Kogge-Stone adder consists of large number of black cells and many wire tracks. A variable latency adder employs speculation: the exact arithmetic function is replaced with an approximated one that is faster and gives the correct...

Flexibility and Portability has increased the requirement of Low Power components in fields like multimedia, signal processing and other computing applications. Adders are the essential computing elements in such applications. However the present adder architectures with hybrid/heterogeneous features provide performance variations but limits to consume less power. In this paper, low power heter...

This paper discusses a rail to rail swing, mixed logic style 1-bit 28-transistor (28T) full-adder, based on a novel architecture. The performance metrics: power, delay, and power delay product (PDP) of the proposed 1-bit adder is compared with other two high performance 1-bit adder architectures reported, till date. The proposed 1-bit adder has a 50% improvement in delay, and 49% improvement in...

Nowadays, VLSI technology mainly focused on High-Speed Propagation and Low Power Consumption. Addition is an important arithmetic operation which plays a major role in digital application. Adder act as the applications of signal processing, memory access address generation Arithmetic Logic Unit. When number transistors increases system designs, makes to increase power complexity circuit. One do...

Many Digital Signal Processing (DSP) algorithms use floating-point arithmetic, which requires millions of calculations per second to be performed. For such stringent requirements, design of fast, precise and efficient circuits is the goal of every VLSI designer. This paper presents a comparison of pipelined floating-point adder complaint with IEEE 754 format with an unpipelined adder also compl...

ÐInteger addition is one of the most important operations in digital computer systems because the performance of processors is significantly influenced by the speed of their adders. This paper proposes a self-timed carry-lookahead adder in which the logic complexity is a linear function of n, the number of inputs, and the average computation time is proportional to the logarithm of the logarith...

This work presents an interpolated flying-adder(FA-) based frequency synthesizer. The architecture of an interpolated FA, which uses an interpolated multiplexer (MUX) to replace the multiplexer in conventional flying adder, improves the cycle-to-cycle jitter and root-mean-square (RMS) jitter performance. A multiphase all-digital phase-locked loop (ADPLL) provides steady reference signals for th...

Power dissipation has become a major issue it has made the way to consider the performance and area so that low power is achieved. Low power is the major requirement for portable multimedia devices employing various signal processing algorithms and architectures. Any computational circuit is incomplete without the utilization of an Adder. Addition is one of the primary operations in arithmetic ...

A Multiplier is one of the key hardware blocks in most digital and high performance systems such as FIR filters, Digital Signal Processors (DSPs), Microprocessors etc., A Wallace tree multiplier is an improved version of tree based multiplier architecture. It uses 4:2, 5:2 compressors and a Carry Select Adder (CSA) to reduce the latency and power consumption. In conventional methods, 10T XNOR s...
