Write an ARM assembly language program in KEIL:

1)In this program you must convert a string to uppercase using a subroutine.

The program should work as followed:

The main program will read a string from memory location, myString. It will pass the characters of the string to the subroutine one at the time, until ALL the characters in the string have been processed. The results received by the main program from the subroutine will be stored back to memory in a new string at the location, upperCaseString, in the same order as the original string

upperCaseString EQU 0x20003000

myString DCB Convert me to Uppercase,0
