the differences have been explained in an excellent manner.i was amazed by the simplicity by which the differences between intel 8080 and 8085 processors were described.it is a perfect description designed for the understanding of an engineering student.
comment on the differance between 8080&8085
The differance is simple and to the point
the difference between 8080 and 8085 is detaily explained
i have pleased on seeing this simplicity,
it is really best for engineering student.
re: Is a Clock Oscillator really a "peripheral"?
I've never thought of the Clock Oscillator of a microprocessor system as being a peripheral device; it's an essential device in a microprocessor's clock generation circuit. From what I've been learning, I'd only term a device as being a peripheral if it's connected to a micro's I/O ports!
