Abstract

The invention discloses a dynamic voltage adjusting system and method. The system comprises a main controller, a power management chip and at least one calculation chip. The calculation chips are usedfor sending calculation error signals to the main controller when it is detected that the error rate of the calculation result exceeds a preset threshold value. The main controller is used for sending a power adjusting command to the power management chip according to the calculation error information and adjusting the power voltages of the calculation chips. Under the fixed frequency, by reducing the voltages, the power consumption of the chips is controlled, and the supply voltages of the chips are reduced to the maximum extent; through hardware detecting, the voltage detection and adjustment time can be greatly shortened, and the power efficiency of the chips and the system is improved.

Description

Technical field [0001] The invention relates to a dynamic voltage adjustment technology, in particular to a dynamic voltage adjustment system and an adjustment method for controlling power consumption by dynamically reducing voltage. Background technique [0002] With the development of integrated circuit technology, the scale of chips has become larger and larger, and power consumption has become an increasingly important issue in integrated circuit design. The dynamic voltage frequency adjustment (Dynamic Voltage Freque ncy Scaling, referred to as DVFS) technology is currently a dynamic voltage frequency adjustment technology widely used in the semiconductor field. DVFS technology specifically dynamically adjusts the operating frequency and voltage of the chip to achieve energy saving purpose. This technology is currently increasingly being used in high-performance computing (HPC) systems, such as multi-core central processing units (CPU), tensor processors (TPU), and virtual ...
