Single-chip power monitor targets FPGA, GPU circuits
Managing and reducing power consumption is crucial in low-voltage, high-power applications such as Field-Programmable Gate Arrays (FPGAs), Graphics Processing Units (GPUs) and embedded computing devices. These devices must first accurately measure power before they can manageit, but precision power measurement solutions are often costly and require multiple ICs or power configurations to measure different rails. […]
