Unformatted text preview: Describe a way that the console could determine when execution reaches the target instruction and puts the processor in single step mode. If you need to, you can add signals between the CPU and the console, but you should try to minimize the use of such signals. Show how to modify the VHDL for the console to implement the breakpoint feature. You may want to print the VHDL for the console and write in your modifications on the printout. You do not need to simulate your changes. You should show the code for modifying bpAdr , turning the breakpoint feature on and off, and the code that stops the processor when an active breakpoint is reached. You may omit the code modifications for the LCD display. CSE 260 – Digital Computers: Organization and Logical Design Homework 9 Jon Turner 11/11/2010...
