Monolithic microcomputer central processor

摘要

A central processing unit (CPU) is utilized in combination with external memories and input/output devices to form a Microcomputer System. The CPU is a 16-bit fixed word length processor monolithically integrated onto a single semiconductor chip which uses two's complement arithmetic for computations. The CPU includes an arithmetic logic unit (ALU), accumulators, data path multiplexers, program counter means, and programmable logic arrays to control operation of the processor.
