ABSTRACT The present invention relates to an information processing apparatus which improves the speed of the data fetch operation from a main storage unit to a central processing unit. The information processing apparatus includes a central processing unit having an access unit. The access unit includes an address control unit, data control unit and MCU interface unit for storing and fetching data corresponding to store addresses and fetch addresses respectively. The address control unit determines whether a fetch address coincides with one of storage addresses. If the fetch address coincides with one of storage addresses, the data fetch operation is suspended until the data corresponding to the store address is stored in the main storage unit. Then, the fetch operation is performed.
