The invention provides a circuit structure, a circuit board and a supercomputing device. The circuit structure comprises at least two stages of operational circuit units; the adjacent operational circuit units are connected; each operational circuit unit is connected with an output unit for outputting a to-be-calculated parameter, and is a minimum unit applied to a circuit of a BLAKE algorithm; and a sequential logic element is arranged between an adder and an XOR gate of each operational circuit unit on the circuit structure, and / or, and the sequential logic element is arranged on the input end of the adder on the circuit structure. Therefore, the BLAKE algorithm can be realized through the circuit structure; moreover, the addition operation and the XOR operation are isolated through thesequential logic element, and / or, the glitch of a signal input into the adder can be removed through the sequential logic element; and therefore, the timing frequency in the circuit structure can be reduced, the propagation of the timing frequency can be prevented, and dynamic power consumption of the whole circuit structure can be reduced.
