Abstract

1,257,760. Data processors. INTERNATIONAL BUSINESS MACHINES CORP. 10 Oct., 1970, No. 48241/70. Heading G4A. A microprogramme controlled data processing system has two or more concurrently operating microprogramme control stores (CS1-CS3, Fig. 1, not shown) so that the execution of more than one instruction can occur simultaneously. The system described includes a number of functionally distinct associative stores, a data store, two work stores, and a status store, each having two input/output registers. The number of control stores is equal to the numbers of functionally distinct associative stores, in this case three. The associative stores contain function tables. In operation the system executes the operations called for by instructions by table look-up operations selected by the instructions. The system main store has a cycle time three times as long as that of the other stores.
