Princeton architecture, also known as Von (pronounced as ‘fon’ and not as ‘bhon’) Neumann architecture, does

treats program memory and data memory separately [Fig. 1.5(b)]. Intel MCS-51 is designed around this
Harvard architecture. ose readers, who are familiar with Intel 8085 microprocessor, may be reminded that
Intel 8085 was fabricated around Princeton architecture.
