Abstract
An MOS/LSI semiconductor chip for providing the functions of an electronic calculator or digital processor includes an data storage RAM, a ROM for program instruction storage, an arithmetic unit for performing operations on data, and control circuitry for defining the functions of the machine in response to instructions from the ROM as well as conditions in the machine and inputs from external. Input and output terminals are provided, as for keyboard input and display output. The operation is digit oriented in that an instruction accesses one digit of the RAM. A special circuit is used which combines several data and control functions including transfer of constants used in calculations from the ROM to the data registers, transfer of keyboard or other data from parallel input lines to an accumulator register or data memory, or to the adder for test or compare, and selection of one of four bits of a digit in data memory for set or reset.
