Energy-Efficient Design of RAM and Its Implementation on FPGA

Abstract

There are many systems which use RAM as its primary memory for example spacecraft, our home computer etc. Energy efficient RAM is even more important in outer space exploration as the power source is very limited and the environmental condition is extreme. Energy efficiency is not only based on the architecture of the system but also on the environmental condition. For that reason, low power RAM will increase the performance of the system even in extreme conditions. In this project, we are advancing towards a design of RAM that will consume less power even in extreme conditions. Four contemporary FPGAs are used for implementation of our RAM design and we find the least power consumer among these four FPGAs architectures. We find a 20.24% reduction in power consumption at 5pF, when we migrate our RAM design from Kintex-7 architecture to Artix-7 Architecture. The results are gathered by using Xilinx Vivado 19.1 tool with VERILOG hardware description language.
