ABSTRACT:
A data processing apparatus is described, including a first bus connecting an instruction storage unit and an instruction preparation unit, a second bus connecting an instruction execution unit and a data storage unit, a bus switch selectively connecting and disconnecting the first and second buses electrically, and a control unit controlling the operation of the bus switch responding to the operations of the instruction preparation unit and the instruction execution unit. When the first and second buses are connected by the bus switch, access from the instruction preparation unit to the data storage unit and access from the instruction execution unit to the instruction storage unit can be performed. On the other hand when the buses are not connected, instruction fetch from the instruction preparation unit and data access from the instruction execution unit can be concurrently performed. Hence, data throughput on the buses can be improved and the load capacity can be reduced, which leads to heightening of the clock frequency.
