Single-chip microcomputers can be easy to program
Bill Huston · 1982
Most single-chip microcomputers (MCUs) use the split-memory Harvard architecture. A few single-chips trace their architectural heritage to large computers due to the common-memory Von Neumann organization. The major differences are that a Harvard-based MCU costs less in its undistorted form, and a Von Neumann-based MCU is more expandable and easier to program.
