Abstract
A digital processor which may be used in a calculator or the like is provided by an MOS/LSI semiconductor chip which contains a ROM or read-only-memory for storing instructions, a bit-parallel arithmetic unit for operating on data stored in a random access memory and control circuitry for defining the operation of the system. The control circuitry includes a programmable logic array for decoding instruction words. Space on the chip is saved by a time-shared decoder which forms part of the programmable logic array and also decodes addresses for the ROM.
