FPGA Implementation of Fault Tolerant & High Speed Reversible Systolic Multiplier

Multiplier is one of the essential components in the digital world such as in digital signal processing, quantum computing, microprocessor and widely used in arithmetic unit. The Reversible rationale is a used to decrease heat scattering and data misfortune. Contrasted with all essential math activities, multiplication requests all the more preparing time and look for complex equipment. This paper presents a plan of low power Systolic Array Multiplier utilizing Reversible logic gates which performs information handling in parallel. In this paper, we present a high speed 4x4 Systolic Multiplier design by using peres gate and toffoli gates and source code written in verilog and also implemented on FPGA Spartan 3s50pq208-4. The synthesis and simulation is done on Xilinx ISE 14.7. The delay is 17.642ns and static power dissipation is 24mW.

Implementation of High Speed Low Power Systolic Multiplier Based on Irreducible Trinomials

This paper presents a high speed low power systolic multiplier based on irreducible trinomials which is implemented using GF (2M). To calculate a set of d partial products in each Handling Element (HE) during every cycle we suggest multiplication algorithm of digit level. By using the systolic channels independently, operands in the proposed structure will be reduced and accumulated by partial products. Functional verification (Simulation) of the multiplier is done by using Xilinx ISE and synthesis is done by using Xilinx XST. The synthesized design is implemented on Zynq7000 FPGA. After completion of the synthesis, it is found that the proposed multiplier achieved power consumption of 2.9mW. Area and the performance of the multiplier is optimized in the proposed structures.

Novel Pipelined Scalable Systolic Multiplier Based on Irreducible All-One Polynomials

A planned productive structure issued for the systolic execution of authoritative based limited field duplication over G F(2 m) in light of final 56-bit AOP is proposed in this work. We extricated a recursive increase calculation and utilized it to plan an intermittent and confined piece level reliance outline (DG) for systolic registering. The intermittent piece level DG is changed into a very smal grained DG, and the pipe coating is utilized for snappier mapping into a parallel systolic design. It doesn't require any overall correspondences for measured decline, in contrast to most current developments. The suggested bit-parallel systolic structure is similar to the parallel systolic structure, however the quantity of registers is altogether lower.

Novel Hybrid-Size Digit-Serial Systolic Multiplier over GF(2m)

Because of the efficient tradeoff in area–time complexities, digit-serial systolic multiplier over G F ( 2 m ) has gained substantial attention in the research community for possible application in current/emerging cryptosystems. In general, this type of multiplier is designed to be applicable to one certain field-size, which in fact determines the actual security level of the cryptosystem and thus limits the flexibility of the operation of cryptographic applications. Based on this consideration, in this paper, we propose a novel hybrid-size digit-serial systolic multiplier which not only offers flexibility to operate in either pentanomial- or trinomial-based multiplications, but also has low-complexity implementation performance. Overall, we have made two interdependent efforts to carry out the proposed work. First, a novel algorithm is derived to formulate the mathematical idea of the hybrid-size realization. Then, a novel digit-serial structure is obtained after efficient mapping from the proposed algorithm. Finally, the complexity analysis and comparison are given to demonstrate the efficiency of the proposed multiplier, e.g., the proposed one has less area-delay product (ADP) than the best existing trinomial-based design. The proposed multiplier can be used as a standard intellectual property (IP) core in many cryptographic applications for flexible operation.
