Simple Microprocessor: Bus Connection and Internals

A microprocessor logic symbol and minimal internal structure.

This device is a bus master or initiator of bus transactions.

It makes a load/read by asserting host read enable: hren.

It writes to addess space (a store) by asserting host write enable hwen.

In this course we are concerned with the external connections only.
