Intro. to Microcomputers Su a 19.9:45 am Q4H, Page 1/1 sem Alhalabi, EE512 Due Jul 3, 2019 Jun 26, 2019 Grade /10 Write an MSP430 assembly language filtering subroutine, ClipFilter, to examine the elements of a list of positive word-size numbers stored at location pointed to by R5. These numbers are actually the digitized values of a sample of analog waveform. The first word in the list is the length of the list. The second word in the list is the max cut-off value before clipping. The subroutine will scan the whole list and clips all values which exceed the max. Clipping means replacing any value which exceeds the max with max value itself.

Answer 1

Answer:

.data
R5: .word 10, 5, 2, 7, 2, 6, 9, 0, 5, 5
.text

main:
jal ClipFilter

li $v0, 10
syscall

ClipFilter:
la $t0, R5 # $t0 points to R5
lw $t1, ($t0) # $t1 has number of digits
lw $t2, 4($t0) # $t2 has max Clipping value

li $t3, 2 # iterator for this list
while: bge $t3, $t1, end
sll $t4, $t3, 2 # $t4 has address of each element in list
lw $t5, R5($t4) # get the digit into $t5
if: ble $t5, $t2, endif
sw $t2, R5($t4)
endif: addi $t3, $t3, 1
b while
end:
