A general-purpose serial operation pipeline that realizes a complicated processing flow with the extemporaneous and explosive amount of operations with respect to various data sizes. A plurality of SALCs that are controlled, individually, and can be operated together with another arithmetic-logic circuit (SALC) 1 are connected in a cascade manner to structure a serial operation pipeline. All of a part of the plural SALCs 1 includes a line for outputting data from an upstream SALC to a downstream SALC, a line for feeding back the data from the downstream SALC to the upstream SALC, and latch circuits 11 to 13 for latching the data on the respective lines, thereby being capable of feeding back the data from an arbitrary SALC 1 to another SALC 1.
