When a load command is issued, first it is decided whether or not the subject address of the load command is stored in a storage buffer. If a hit occurs in the storage buffer, in other words if data is present which has this address, this data is output as load data. On the other hand, if no hit occurs in the storage buffer, a decision is made as to whether or not said data is stored in a cache memory, and if said data is thus stored then, along with this data being read out as load data, the load data which has been read out from this cache memory is stored in the storage buffer.
