Introduction Now that you have the basic skills to deal with QtSPIM, in this lab we're going to explore the structure of an assembly language program, and learn how to interpret and modify assembly programs 2. Program structure: Let's start by looking at the minimum requirements of a working assembler program. Even a simple assembler program requires quite a few lines. Considering the following program: 1. Write a MIPS Assembly Language program that prompts the user to enter two integers, save them in registers $s0 and $s1, swap the contents of those two registers, and display to the screen their final contents. 2. What is the character string corresponding to the following ASCII codes? 0x6E616874 0x756F796B 0x0000000A 3. Translate the following assembly language instructions to their corresponding MIPS machine language codes as they would be represented in hexadecimal. addu $a0,$0,$ t0 ori \$v0, \$0, 4 andi $s0,$s7,0xFFC0
