Good luck with your project.
Silicon base micro processors started back around 1971.
These early Processors had about 2300 transistors. They were incredible for their day.
The 8080 processor had over 50,000 by 1980 and ushered in the era of personal PC's making a simple computer somethig the average person could afford.
Today's processors have around 2,000,000,000 transistors.
If you figure a discreet transistor is about 1/4 in in size, it would require a circuit board the size of 18 football fields to mount all the transistors in a modern processor.
The guys that design this processor are something else.
