PROGRAMMING WITH MARS IDE DECISIONS AND LOOPS
The purpose of this lab is to introduce you to the layout and structure of the Mars
IDE development tool, as well as decision and loop statements. In this lab, the
MIPS assembly language is used.
Answer the following question in addition to the LAB.
The MIPS assembly instructions that can be used are determined by what number
formats are present. For this assignment, you’ll need to know how to perform an
arithmetic operation given different representations of the same number.
What is 5ED4 – 07A4? Assume these numbers are represented as unsigned 16-bit
hexadecimal numbers. Show your work.
What is 5ED4 – 07A4? Assume these numbers are represented as signed (two’s
complement format) 16-bit hexadecimal numbers. PROGRAMMING WITH MARSIDE
DECISIONS AND LOOPS
The purpose of this lab is to introduce you to the layout and structure of
the MarsIDE development tool in addition to Decision and Loop statements. In this
lab, the MIPS Assembly language is used.
I. Follow the same procedure in Lab1.
II. From the main menu, choose “File”? “New”
III. You will find a blank file. Start typing the following program.
IV. Click on the icon “Assemble the current file”
V. Run the programby “Run one step at a time” as shown below
• Observethe registers/Memory locations values after each Step Run. Record
these values in Table 1.
You should type or copy and paste the values from the Mars environment to the table
below using Microsoft office.
1- Draw the memory and its contents starting from address 268500992.
2- What does the final value of $s3 represent?
$s3 $s5 $s6 $t0 $t1 m[$s6] m[$s6+4] m[$s6+8]
m[$s6+12] m[$s6+16] m[$s6+20] m[$s6+24] m[$s6+28]
