Samsung patents chip controller that adjusts power based on system resonance
Samsung has received a patent for a controller that manages the voltage and speed of a computer chip. It calculates a specific 'resonance frequency' by analyzing how the chip's power system reacts to changes, then uses this data to fine-tune power delivery in a closed loop.
In the filing’s own words
A Dynamic Voltage and Frequency Scaling (DVFS) controller, an integrated circuit including DVFS, and a method of operating the DVFS controller are provided. The integrated circuit includes at least one subblock circuit configured to process an instruction, and a DVFS controller configured to control a power management unit (PMU) and a clock management unit (CMU) to control an operating voltage and an operating frequency, respectively, based on a resonance frequency calculated from a frequency response resulting from dynamic characteristics of an entire power system including the PMU, a power delivery network (PDN), and the subblock circuit.
What exactly they claim (claim 1)
1. An integrated circuit, comprising: at least one subblock circuit configured to process an instruction; and a dynamic voltage and frequency scaling (DVFS) controller configured to control a power management unit (PMU) and a clock management unit (CMU) to control an operating voltage and an operating frequency, respectively, based on a resonance frequency calculated from a frequency response resulting from dynamic characteristics of an entire power system, the entire power system including the PMU, a power delivery network (PDN), and the at least one subblock circuit, wherein the DVFS controller is configured to perform a closed-loop control operation of the PMU and CMU to control the operating voltage and the operating frequency, respectively, based on the resonance frequency.
