ABSTRACT:
A variable function system utilizes a fixed program memory array such as a programmed read only memory in which a number of programs are stored depending upon the desired functions of the system. The system also includes a program counter, an instruction register, control decoders, jump-condition circuits, a clock generator, a timing generator, key input logic, data storage array, an arithmetic logic unit, an output decoder, and a digit scanner which scans both the keyboard and display outputs. The read only memory may be programmed so that the system provides a variety of functions. A preferred embodiment of the invention is capable of being fabricated as a monolithic integrated semiconductor system utilizing contemporary metal-insulator semiconductor techniques.
