In this paper, we have tried to make energy efficient ALU on 90nm based Virtex-4 FPGA using different I/O standards, as with the scaling of technology power dissipation has become a major concern for high performance ALU design. As 50% of the total power of ALU is dissipated only in clock and I/O pads, hence in order to make it energy efficient clock gating technique is introduced and the analysis...
In this paper 64-bit energy efficient Arithmetic Logic Unit (ALU) is designed in verilog with the help of clock gating technique. We can reduce dynamic power and dynamic current of 64-bit ALU by using clock gating technique. This design is implemented on XC6VLX75T device, −3 speed grade and Virtex-6 FPGA. When clock logic is applied to target device, we are achieving 67.74% and 65.84% less reduction...
In this paper, we apply clock gating technique in Global Reset ALU design on 28nm Artix7 FPGA to save dynamic and clock power both. This technique is simulated in Xilinx14.3 tool and implemented on 28nm Artix7 XC7A200T FFG1156-1 FPGA. When clock gating technique is not applied clock power contributes 32.25%, 4.24%, 3.06%, 3.09%, and 3.09% of overall dynamic power on 100 MHz, 1 GHz, 10 GHz, 100GHz...
In this work, Virtex-6 is Target 40nm FPGA Device. Xilinx ISE 14.1 is an ISE Design tool. RAM is a target design. Clock Gating is a technique which decreases clock power but increases Logic Power due to added Logic in Design. Irrespective of increase in number of Signal and IO buffer due to Clock Gating, there is significant decrease in IO Power and Dynamic Power due to decrease in number of frequency...
In this work, our focus is on study and analysis of various clock gating technique and design and analysis of clock gating based low power sequential circuit at RTL level. Virtex-6 is 40-nm FPGA, on which we implement our circuit to re-assure power reduction in sequential circuit. Clock gating is implemented on smaller circuit called D flip-flop and on larger circuit called 16-bit register. The percentage...
