ABSTRACT:
An electronic digital processor is disclosed of the type used in miniature calculators. The processor is fabricated as a single MOS-LSI semiconductor chip and includes a large read-only-memory or ROM for storing instruction codes, along with addressing circuitry for generating addresses for the ROM by either sequencing a program counter or by branching to an address contained in a branch instruction code. At the same time as a branch instruction is implemented, parts of the instruction code used for the branch address may be employed as an op code to perform operations within the processor.
