Abstract
An arithmetic operating system for rapidly executing an instruction having an operand relating to an arithmetic operation stored in a main storage is disclosed. An operand necessary for a succeeding arithmetic operation is read from the main storage prior to the writing of an intermediate operation result to the main storage so that the succeeding arithmetic operation and the writing of the intermediate operation result can be overlapped in time.
