Dynamic D flip-flop, data operation unit, chip, hash board and computing device

Abstract

The invention provides a dynamic D flip-flop, and a data operation unit, a chip, a hash board and a computing device using the same. The dynamic D flip-flop comprises: an input terminal, an output terminal and at least one clock signal terminal; a first latch unit for transmitting data of the input terminal and latching the data under control of a clock signal; a second latch unit for latching data of the output terminal and inversely transmitting the data latched by the first latch unit under control of a clock signal; and an output driving unit for inverting and outputting the data received from the second latch unit; wherein the second latch unit outputs in high level, low level and high impedance states by means of a single element under control of a clock signal. Therefore, the invention can effectively reduce chip area, power consumption, and logic delay.
