Title:
REGISTER, CENTRAL PROCESSING UNIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/160047
Kind Code:
A1
Abstract:
Provided in the present application are a register, a central processing unit and an electronic device. The register comprises a first latch, a second latch and a logic gate, wherein an input end of the first latch is connected to a clock signal input end, a data input end, and an output end of the logic gate; an output end of the first latch is connected to an input end of the second latch; and an output end of the second latch is connected to a data output end. An input end of the logic gate is connected to the data input end and the data output end, and the output end of the logic gate is connected to the first latch. When the potential of the data input end is the same as the potential of the data output end, the logic gate can control the output potential of the first latch to be the same as the potential of the data output end, such that signal flipping of the clock signal input end does not cause flipping of a node inside the register, and accordingly the power consumption of the flipping of a clock signal inside the register can be reduced.
