How to find the smallest value in memory

Does your task revolve around finding the smallest value in memory? Would you like an expert to guide you through it? Contact us right away. We are the leading academic writing service and would be thrilled to offer you the assistance you seek.

Assignment 11: If you require help with your Assembly language proect or need a Assembly language online tutor to help you complete your Assembly language proect then we can provide that for you.

Finding the smallest value in memory

  • $500 contains an array of words, with the number of elements in D0. Write a routine that finds the smallest value and stores it the memory pointed to be A0.
  • The program should start at $2000.
  • Fix any syntax errors after you assemble.
  • Start the simulator, and set registers and add edit the array.
  • Run the program and check that result is the result intended.
  • You need to reset PC if you want to rerun the program.
  • Show the screenshots of the program in action, to show the workings.
Solution: You will find a sample Assembly language project, that indicates the quality of the work we can do for you.

program.X68

ORG $2000
SMALLEST: ; smallest subroutine
; address of place to save the minimum is in A0
; number of elements in the array is in D0
MOVEM.L D0-D2/A0-A1,-(SP) ; save used registers in the stack
MOVE.L #$500,A1 ; load A1 with the array address $500
MOVE.W (A1)+,D1 ; load first value from the array into D1, which will hold the minimum
SUBI.L #1,D0 ; we used the first number, decrement element count
LOOP:
CMP.L #0,D0 ; if the count is zero
BEQ DONE ; we are done
MOVE.W (A1)+,D2 ; load a number from the array
CMP.W D1,D2 ; compare the current element with the minimum
BGT NEXT ; if the element is bigger than the minimum, skip
MOVE.W D2,D1 ; otherwise, set element as new minimum
NEXT:
SUBI.L #1,D0 ; decrement number of elements to compare
BRA LOOP ; repeat
DONE:
MOVE.W D1,(A0) ; at the end D1 has the minimum, save it in the given address
MOVEM.L (SP)+,D0-D2/A0-A1 ; recover saved registers from the stack
RTS ; return from subroutine
END SMALLEST
Instructions For running it I used the following starting values: D0 = 10 A0=$1000 Memory data in $500: 8, 4, 7, 3, 6, 2, 5, 9, 1, 2, all words (2 bytes each) The file "screenshot-start.png" shows the initial screen for the simulator. After running you can see in the "screenshot-end.png" that memory position $1000 has the value 1, which is the minimum, or smallest value in the array. The code is written as a subroutine as requested, it saves the registers it uses at the start of the subroutine and it restores their value at the end of it, the subroutine exits with the instruction RTS or return from subroutine. Below is a Assembly language project, but if you just require a Assembly language online tutor then we can do that for you as well.
