Solved by verified expert:Write a program in PLP assembly that repeatedly reads the value of the switches (address: 0xf0100000) and
displays a pattern on the LED array based on what switches. Each time the switch value is read, the pattern
should be displayed regardless of whether the switch value has changed or not since the last time it was read.
The table below indicates the pattern that should be displayed for each possible switch setting:switch hex binary0 0x00000001 0b00000001 Turn all 8 LEDs on and then off 1 0x00000002 0b00000010 Turn all even numbered LEDs on and
then off 2 0x00000004 0b00000100 Turn all odd numbered LEDs on and then
off 3 0x00000008 0b00001000 Cycle through all 8 LEDs in order with
only one LED on at a time (a marquee)

CSE 230 Project 2: LED Pattern Generator
Learning Objectives:
●
Use PLP branch instructions
●
Read from a memory mapped I/O device
The Task:
Write a program in PLP assembly that repeatedly reads the value of the switches (address: 0xf0100000) and
displays a pattern on the LED array based on what switches. Each time the switch value is read, the pattern
should be displayed regardless of whether the switch value has changed or not since the last time it was read.
The table below indicates the pattern that should be displayed for each possible switch setting:
Switch
Hexadecimal
Binary Switch
LED Pattern
Number
Switch Value
Value
0
0x00000001
0b00000001
Turn all 8 LEDs on and then off
1
0x00000002
0b00000010
Turn all even numbered LEDs on and
then off
2
0x00000004
0b00000100
Turn all odd numbered LEDs on and then
off
3
0x00000008
0b00001000
Cycle through all 8 LEDs in order with
only one LED on at a time (a marquee)

All LEDs off
Hint: Logical shifts are not required to complete this project, but they should make your program shorter and
more readable than hard coding every value to be written to the LEDs. Shifts can also be helpful when
determining the switch value.
