Reconfigurable systems and reconfigurable array structures and their applications

Abstract

The invention discloses a reconfigurable system and a reconfigurable array structure and an application of the reconfigurable array structure. The reconfigurable array structure comprises an input unit, an output unit, a calculation unit line, an interconnection unit and a lookup table unit, wherein data is transmitted among line structures of a calculation array through the input unit and the output unit; the calculation unit line consists of a plurality of arithmetical logic units; the arithmetical logic units can be configured to realize corresponding calculation functions; the interconnection unit consists of a line input multiplexer and a substitution network; the line input multiplexer is responsible for selecting input to be transmitted to the substitution network; the substitution network is responsible for substituting the input in any non-repeat mode and outputting the substituted input; and the lookup table unit is used for performing table lookup operation according to an output result of each line of reconfigurable unit, and outputting a table lookup result to a next line. Through adoption of the reconfigurable array structure suitable for a block cipher algorithm, the assembly line depth can be reduced, and the hardware resource utilization ratio is increased, so that substitution operation in the block cipher algorithm is optimized, and efficient processing of the block cipher algorithm is realized.
