Abstract

The invention discloses a reconfigurable operator, which comprises a power consumption control module, wherein the power consumption control module is used for controlling the power consumption of the reconfigurable operator; and the power consumption control module can control the power supply situation of the reconfigurable operator when a functional unit of the reconfigurable operator does notrealize any specific function, or control output data according to the continuity of data processing of the reconfigurable operator when the reconfigurable operator realizes some specific function soas to fulfill the aim of reducing the power consumption. The invention also discloses an integrated circuit which comprises the reconfigurable operator. The invention also discloses a method for reducing the power consumption of the reconfigurable operator according to a principle of controlling the power consumption by the reconfigurable operator.

Description

technical field [0001] The invention relates to the field of integrated circuit design, in particular to a reconfigurable operator, an integrated circuit and a method for reducing power consumption of the reconfigurable operator. Background technique [0002] In early integrated circuit design, due to the low integration level and low clock frequency of integrated circuits, area and time were the key considerations for designers. The direction that IC designers pay attention to is: the smallest chip area and the fastest clock speed. [0003] In recent years, with the development of integrated circuits, especially the significant increase in integration and clock frequency, the power consumption of integrated circuits has also increased crazily. The power consumption problem of integrated circuits has become a screen neck restricting the development of integrated circuit design level. Therefore, for integrated circuit designers, power consumption has become as important as ...
