摘要:
In an operation unit wherein a series of data is sequentially applied, a predetermined operation is performed in synchronism with the input data in a pipelined manner, and the predetermined operation is applied to an input data and the result of the predetermined operation for a preceding input data. There are provided a plurality of partial operation devices which respectively compute a plurality of different partial data of a result data to be obtained as a result of the predetermined operation, and when one of the partial data is obtained, the one partial data is immediately used for the operation for the subsequent input data. Consequently, the operation for the subsequent input data can be started before the operation for the remainder of the partial data of the preceding input data is completed.
