Abstract:

Adders are widely used as essential parts in the design of digital integrated circuits. The Carry Select Adder (CSA) is unique among conventional adder topologies in that it operates quickly. There is a need for speedier arithmetic units as well as ones that use less power and take up less space as the mobile sector grows quickly. The Carry-Select method for adder design with carry propagation achieves a good trade-off between performance and cost. However, because it uses two ripple carry adders (RCA), the traditional CSA design still has a significant area overhead. A Binary to Excess-1 code

Abstract:

In the design of Integrated circuits, area occupancy and power consumption plays a vital role because of increasing 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, it is clear that there is scope for reducing the area and power consumption in the CSLA. This work uses a simple and efficient transistor level modification of EX-OR gate used in BEC-1 converter to significantly reduce the area and power of the CSLA.

Abstract:

Carry select adder is a square-root time high-speed adder. In this paper, FPGA-based synthesis of conventional and hybrid carry select adders are described with a focus on high speed. Conventionally, carry select adders are realized using the following: (i) full adders and 2 : 1 multiplexers, (ii) full adders, binary to excess 1 code converters, and 2 : 1 multiplexers, and (iii) sharing of common Boolean logic. On the other hand, hybrid carry select adders involve a combination of carry select and carry lookahead adders with/without the use of binary to excess 1 code converters. In this work,

Abstract:

In this paper, a high-speed parallel residue-to-binary converter is proposed for a recently introduced moduli set Sk={2m−1,220m+1,221m+1,…,22km+1} for a general value of k. The proposed converter uses simple cyclic shift and concatenation operations and does not require any multiplier. Individual converters for the cases of k=0 and k=1 are derived from the general architecture and compared with those existing in the literature. The converter for S0 is twice as fast requiring only one-half of the hardware, while that of S1 is three times as fast, but requiring only 60% of the hardware, as compa

The excess properties for the binary systems were determined and successfully fitted to a polynomial equation of the Redlich–Kister type.

Signed-digit number systems support carry-free, constant time addition. By introducing the signed-digit number arithmetic into a residue number system (RNS), arithmetic operations can be performed efficiently. In this paper, a new algorithm for residue-to-binary conversion for four moduli set {2n-1, 2n + 1, 22n + 1, 2n} that only requires modulo 24n - 1 SD number addition is proposed. This moduli set has 5n-bit dynamic range. Based on the proposed algorithm, the converters are designed with a two-level binary tree structure formed by the modulo 24n - 1 SD number residue adders.
