A very large scale integrated circuit for performing a bit-serial matrix transposition operation, comprising an input shift register module for inputting N multiplied results of two NxN matrixes in the unit of k bits and outputting them in the unit of k/N bits in response to a load signal, a bit-serial transposition module for selecting k/N-bit data from the input shift register module in response to a switching control signal, an output multiplexer module for selecting k/N-bit data from the bit-serial transposition module in response to the switching control signal, and an output register module for inputting output data from the output multiplexer module in the unit of k/N bits and outputting N data in the unit of k bits. According to the present invention, when an NxN matrix transposition operation is performed, the operation occupancy of transposition cells becomes 100% after an N-input delay occurs. Also, the processing unit of data becomes smaller by using a bit-serial processing algorithm. Therefore, the high-speed operation can be performed. Further, the number of gates can be reduced in the integrated circuit. Moreover, because the integrated circuit has a pipelined structure, it is applicable to a multi-dimensional signal processing system requiring a high-speed processing operation.
