Benchmarking of Radix-2 Sequential Multiplication using five Xilinx FPGA families.
This paper presents description on the implementation of fast radix-2 sequential multiplier using repeated carry save addition (CSA) method with variable data path sizes ranging from 8 bits to 1024 bit.
The main objective of this paper is to achieve the best achievable time delay reduction with better performance (i.e. frequency) running on FPGA platforms and prove their applicability in high performance reconfigurable computing.
The design was implemented using VHDL description language and synthesized using five different Xilinx FPGA chip families, namely: vertix7, kintex7, artix7, zynq7 and spartan6. Rigorous tests were conducted and analyzed in terms of maximum frequency and total delay time of the FPGA design as well as the hardware utilization.
The results on the code synthesizing demonstrated that the proposed 1024-bit sequential multiplier with kintex7 chip family outperforms others with a maximum frequency of 296 MHz, while Spartan 6 recorded the lowest frequency with 140 MHz.
The performance of the proposed multiplier-based CSA was benchmarked against other state-of-the-art designs which results reflected its superiority in terms of throughput of two or more multiple times as compared to others.
