Dynamic voltage regulation design method based on fuzzy logic control

Abstract

The invention provides a dynamic voltage regulation design method based on fuzzy logic control. The characteristics, generated when fuzzy logic processes uncertain information, of the fuzzy logic are used for maintaining user satisfaction and reducing frequency and voltages as much as possible at the same time, and therefore power consumption is controlled. In order to optimize a system by taking the user satisfaction as indexes, the method solves the two problems of measurement of the user satisfaction, and a voltage regulation method. For the problem of the measurement of the user satisfaction, the user satisfaction is achieved and compared by dynamically measuring performance appreciable by a user on the basis of system video output, and through the voltage regulation algorithm design based on the user satisfaction, and user experience practice in a certain sample and statistics of system consumption are carried out. An OpenOffice Word application program is selected in the man-machine interaction environment to conduct word processing. According to practice verification, two hundred people can be randomly selected from all kinds of people to be used as respondents, the satisfaction and power consumption situations of the respondents on the Word application program are compared respectively on the condition that voltage regulation does not exist and on the condition of the DVFSBFL algorithm implementation of the design, and the dynamic voltage regulation advantages of the dynamic voltage regulation design method based on fuzzy logic control can be obtained when comparison reference system statistic analysis is conducted.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a fuzzy control-based dynamic voltage regulation design method. Background technique [0002] The power consumption of computer system is one of the problems to be solved urgently in the further development of computer technology. The dramatic increase in power consumption drives up the packaging and cooling costs of the chip. Executing in a high temperature environment increases the failure rate of the chip, resulting in a decrease in the stability of the computer system. There are many technical researches on reducing the power consumption of the system, but most of them are based on performance index considerations (such as system throughput rate, etc.). But the ultimate evaluation of machine performance is whether it can meet the needs of users, that is, improving user satisfaction is the fundamental purpose of computer system design. Due to the ambiguity of ...
