Question

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.

- please use"sw" "li", labels, loops, "beq" and "lw" to create the code. The code is for assambly language and it will be compiled and run on PLPTool version 5.2.

I have created the following code it is not completed it. I seem to be stuck here. Please complete it, following the task instructions.

# main source file

.org 0x10000000

_start:

# Initialization

li $t0,0xf0100000 # Load address of switches

li $t1,0xf0200000 # Load address of LEDs

li $t5,1 # Load value of switch 0 address of LEDs

li $t6,2 # Load value of switch 1 address of LEDs

li $t7,4 # Load value of switch 2 address of LEDs

loop:

# Read switch value

lw $t2, 0($t0) # Load switch value into $t2

# Generate LED pattern based on switch value

beq $t2,$t5, switch_0 # Switch 0 pattern

beq $t2,$t6, switch_1 # Switch 1 pattern

switch_0:

li $t3, 0xf # Pattern for switch 0 (LEDs 0-3 on)

sw $t3, 0($t1) # Update LEDs with generated pattern

j loop # Repeat loop

switch_1:

li $t3, 0b11110000 # Pattern for switch 1 (LEDs 4-7 on)

sw $t3, 0($t1) # Update LEDs with generated pattern

j loop # Repeat loop

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:

Turn on LEDs 0, 1, 2, and 3, then set all 8

Turn on LEDs 4, 5, 6 and 7, then set all 8
LEDs to off

0х00000004
0600000100
4
Create a scrolling pattern that moves
from right to left starting with LED 1 and
skipping every other LED. Only one LED
should be on at any given time (i.e., LED
1, then LED 3, then LED 5, then LED 7)
and the pattern should end with all LEDS
off.
