Lab 4 – CV-8052 Soft Processor
Copyright © 2011-2021, Jesus Calvino-Fraga. Not to be copied, used, or revised without explicit
written permission from the copyright owner.
Introduction
For this laboratory assignment you will setup the CV-8052 soft processor into the Altera
DE0-CV, as well as write programs that can be loaded and run in the CV-8052.

Components Required for this Module
For this module you will need the Altera DE0-CV board with both Quartus Prime and
CrossIDE installed in your computer. Also for this module you will need the Quartus Prime
project available in the course web page: CV_8052.zip.

Laboratory Requirements

1. Follow the instructions in the ‘CV-8052 Soft-Processor Getting Started Guide’ available
in the course web page. Make sure the program ‘blinky.asm’ described in the guide
works in your Altera board.

2. Write, compile, download, and test an 8051 assembly language program that displays
your student number using the 7-segment displays available in the Altera DE0-CV
configured as a CV-8052 soft processor (HEX0 to HEX5) using the formats listed
bellow. The display format depends on the states of switches SW2 down to SW0 after
they are latched by pressing pushbutton ‘KEY3’. In all the examples it is assumed that
the student number is “12345678”. You MUST use your own student number!

000: Display the six most significant digits of your student number using HEX5 down to
HEX0. For example: “123456”

001: Display the two least significant digits of your student number using HEX1 and
HEX0. Keep HEX5 down to HEX2 blank. For example: “ 78”

010: Starting with the six most significant digits of your student number, scroll one digit
to the left every second. This should keep going forever until the selection for SW2
down to SW0 is changed. For example: “123456”, “234567”, “345678”, “456781”,
“567812”, “678123”, etc.

011: Starting with the six most significant digits of your student number, scroll the digits
of your student number one digit to the right every second. This should keep going
forever until the selection for SW2 down to SW0 is changed. For example: “123456”,
“812345”, “781234”, “678123”, “567812”, “456781”, etc.


2
100: Make the six least significant digits of your student number blink every second.
This should keep going forever until the selection for SW2 down to SW0 is changed. For
example: “345678”, “ “, “345678”, “ “, etc.

101: Make the six most significant digits of your student number appear one at time
every second, starting with a blank display. This should keep going forever until the
selection for SW2 down to SW0 is changed. For example: “ “, “1 ”, “12 ”,
“123 ”, “1234 ”, “12345 ”, “123456”, “ “,“1 ”, etc.

110: Display “HELLO ” for one second, then the six most significant digits of your student
number for one second (for example “123456”), followed by “CPN312” for one second.
This should keep going forever until the selection for SW2 down to SW0 is changed.

111: Display your student number (or part of it) using a format of your own creation that
is different from any of the formats required above.

Upload to canvas the assembly source code of your program as well as a video
demonstration of all the patterns required above.
