Embodiment 1

[0033] Please refer to figure 1 , the reconfigurable operator 200 of the present invention adds a power consumption control module 202 in its structure, and the power consumption control module 202 is used to control the power consumption of the reconfigurable operator 200 . For example, the purpose of reducing the power consumption of the reconfigurable operator 200 is achieved by controlling the power supply and / or the change of output data of each part in the entire reconfigurable operator 200 .

[0034] The reconfigurable operator 200 is provided with multiple interfaces for realizing communication with the outside, and the interfaces include: data input interface, data output interface, configuration clock interface, power supply interface, ground interface, configuration information transmission link interface (including configuration information entry and Configuration information export) and working clock interface. Among them, the configuration information transmissi...

Embodiment 2

[0045] An integrated circuit includes at least one reconfigurable operator 200 as described in Embodiment 1, and the reconfigurable operators 200 are distributed and arranged in columns.

[0046] Figure 5 As a part of the structure of the integrated circuit, it is an array processing structure 100 in which operators are distributed and arranged in columns.

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 not realize 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 so as 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 ...
