Title:
DYNAMIC D FLIP-FLOP, DATA OPERATION UNIT, CHIP, HASH BOARD AND COMPUTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/001167
Kind Code:
A1
Abstract:
A dynamic D flip-flop (400, 500, 600) and a data operation unit (700) using same, a chip (800), a hash board (900) and a computing device (1000). The dynamic D flip-flop (400, 500, 600) comprises an input end (404), an output end (405) and at least one clock signal end; a first latch unit (401), configured to transmit data of the input end (404) and latch the data under the control of a clock signal; a second latch unit (402), configured to latch data of the output end (405) and perform inverted transmission, under the control of a clock signal, on the data latched by the first latch unit (401); and an output driving unit (403), configured to invert and output the data received from the second latch unit (402); the first latch unit (401), the second latch unit (402) and the output driving unit (403) being sequentially connected in series between the input end (404) and the output end (405); the second latch unit (402) realizing, under the control of a clock signal, output in three states at a high level, a low level or a high resistance by means of a single element. Therefore, the present invention effectively reduces chip area, power consumption, and logic delay.
