Abstract

1,036,644. Electric digital calculators. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 31, 1965 [May 14, 1964], No. 20094/64. Heading G4A. In a data processer comprising a control store storing both micro-instructions and a table of information, a control cycle reads out a microinstruction which may initiate a table look-up cycle to read information from the table. Addition by table look-up, digit by digit, is described. The control store may be a read-only store as in Specification 985,347 which is referred to.
