CPU core voltage
The CPU core voltage (VCORE) is the power supply voltage supplied to the processing cores of CPU (which is a digital circuit), GPU, or any other device with a processing core.
CPU core voltage
OverviewPower saving and clock speedDual-voltage CPUMulti-Voltage CPUExternal linksThe CPU core voltage (VCORE) is the power supply voltage supplied to the processing cores of CPU (which is a digital circuit), GPU, or any other device with a processing core. The amount of power a CPU uses, and thus the amount of heat it dissipates, is the product of this voltage and the current it draws. In modern CPUs, which are CMOS circuits, the current is almost proportional to the clock speed, the CPU drawing almost no current between clock cycles. (See, however, subthreshold leakage.)
FPGA Power Supply Considerations
VOLTAGE REGULATORS There are two popular types of regulator that can be used to power the FPGA. These will receive an input voltage which is usually supplied by an off-line SMPS and can
