Abstract
PURPOSE:To accelerate processing speed, by taking out data from a buffer when a fetch instruction is outputted during a move-in operation and the data exists on a move-in buffer. CONSTITUTION:A data selection means 15 is provided which discriminates the existence of the data corresponding to the fetch intruction on a move-in buffer means 14 when the instruction is issued from an instruction processing means 11 during the move-in operation, and when it exists, selects the output of the move-in buffer means 14 not the output of a buffer accumulation means 13, and outputs it to the instruction processing means 11 as fetch data 20. Therefore, in such case, it is possible to take out the data directly from the buffer, and it is not required to wait the storage of move-in data in the buffer accumulation means from the move-in buffer. In such a way, the processing speed can be accelerated.
