Kind Code:
A
Abstract:
PURPOSE:To avoid useless operations and to improve the efficiency of control, by providing a means to store temporarily both address and sequence data on the basis of a first-in/first-out rule. CONSTITUTION:A stack part is provided to temporarily store both address and sequence data on the basis of a first-in/first-out rule. For instance, the prescribed address data (b), sequence data (k) and starting signal ( ) are formed and delivered by an input part 1 on the basis of the contents of the input data (a). Then the stack data (c) is formed and delivered by a stack writing control part 2 and then written to a first-in/first-out stack part 3. Then the answer signal (m) is transmitted to an input part 1 to prepare for input of the next data, and at the same time a synchronizing signal n1 is produced and sent to an instruction control part 4. Then the stack data is written and read out on the basis of a command given from the part 4 and a first-in/first-out rule, and the instruction data stored in an instruction storage part 5 is calculated via an arithmetic circuit 6. The result of this culcuration is delivered to an output part 7.
