Abstract

PURPOSE:To speed up the data processing, by fetching data to an internal data register with a data pickup device in the order requested by an operation processing device. CONSTITUTION:A memory data register 43 which reads out data in 11 units of memory interface bounder from a storage device 10 and stores it temporarily, is provided. Further, a merge register 44 storing the content of the register 43, a byte selector 45, a byte circular register 22, and a data pickup device 40 controlling the register 22 and the selector 45 according to the instruction from an operating processing device 20 are provided. The content of the storage device 10 is stored in an internal register 21 in the order in accordance with the instruction from the operating processing device 20.
