Frequency Scaling Based Green Mobile Battery Charge Controller Sensor Design on FPGA

Abstract

Frequency Scaling based energy efficient MBCCS is implemented in this paper. In this design, if battery's voltage or current is less than threshold then battery will continue charging. Whereas, if voltage or current is more than threshold then it will ring Overcharge Alarm. With Frequency Scaling, we reduce frequency from 1THz to 25GHz, where 125GHz, 625GHz are intermediate frequency value. There is 97.50%, 100%, 97.54%, 97.48%, 20%, 96.48 % reduction in clock power (CP), logic power (LP), signal power (SP), IOs power (IOP), leakage power and total power dissipation respectively when we scale down frequency from 1 THz to 25GHz.

Implementation of Efficient Night Vision Robot on Arduino and FPGA Board

“…Result of LDR simulation on FPGA at frequency 1GHz for different values of output load is shown in Table 1. FPGA is the best architecture for testing of energy efficient design [9][10][11][12][13][14][15][16][17][18]. There are many energy efficient techniques used in low power electronics design.…”

“…There are many energy efficient techniques used in low power electronics design. These are CTHS [9], IO standards [10], Mobile DDR IO standard [11], Voltage Scaling [12], Frequency Scaling [13], CGVS [14], Mapping [15], Thermal Mechanics [16], and Ambient Temperature Scaling [18]. In order to make energy efficient night vision robot, we simulate and implement LDR on FPGA as shown in Figure 1 suign output load scaling.…”
