Info

Together, the state machine and datapath implement the serial multiplication. The state machine is a Mealy Machine, so you would need two processes to describe it. The datapath can be described using simple components as you did in Lab 3. See Page 684-685 in textbook if you want to see the VHDL Lecture 10, Page 28
This datapath looks something like that from Lab 3 Lab 3 was a general-purpose datapath: - It was designed to implement any program - The controller was designed to decode an assembly language instruction and stimulate the control signals appropriately The divider was application-specific - It was designed specifically to implement the divider - The controller was designed specifically for this application You could think of the divider as a little “processor”, but all it really does is implement the division algorithm Lecture 10, Page 29
