Abstract
A buffer or a plurality of buffers are provided each for holding a write address and an address specifying a write position which are obtained as a result of an execution based on a predicted result. The execution of the instruction is continued up to the operation stage regadless of whether or not the instruction is being executed in the predicted state, the data and the write address are held in the buffer written. The data in the buffer is canceled if the prediction is found to be wrong when the predicted state is completed, and the data is utilized if the prediction is found to be correct.
