Integrated microprocessors
Morton H. Lewin · IEEE Transactions on Circuits and Systems · 1975
The existence of a component called a "microprocessor" is a natural outgrowth of our present ability to fabricate digital integrated circuits with immense internal complexity. A discussion on the internal logical structure of a typical microprocessor, the external interface it presents, how its performance parameters may be defined and measured, and some of the properties of systems in which it may be embedded, is presented.
