This assignment requires you to take an ARM assembly language program and simulate it$.$ The program

is available in the file array$\_$plus$\_$scalar.asm.

Part A

$1.$ Install uVision on your computer using the Getting Started with Keil uVision document or go to

the lab in ENG $228.$

$2.$ Start uVision.

$3.$ Create a new project using Project $->$ New uVision Project.

$4.$ Navigate to the desired directory $($I suggest the same directory as the $.$asm file$)$ and give the

project a name.

$5.$ You will be asked to $$Select Device for Target $$Target $1....$ Select Legacy Device Database $[$no

RTE$]$ for the first pull down and then select ARM $->$ ARM$7($Big Endian$).$

$6.$ Add the source file to the project by using Project $->$ Manage $->$ Project Items.

$7.$ In the Manage Project Items popup, click on Add Files and select array$\_$plus$\_$scalar.asm $($you

may need to change the filter to All Files to see it$).$ After you select the file, click on Add and

then on Close. You should now be back in the Manage Project Items window and see

array$\_$plus$\_$scalar.asm under Files. Click OK$.$

$8.$ Use Project $->$ Build Target to run the Assembler.

$9.$ Debug the program using Debug $->$ Start$/$Stop Debug Session

$10.$ You$$ll see a popup window that says you are using the evaluation version and have a code limit

of $32$ K$.$ Click OK$.$

$11.$ Set up the memory map using Debug $->$ Memory Map

$12.$ In the memory map popup window, enter a map range equal to the current mapped region,

with the beginning and ending address separated by a comma. Click on Read, Write, and

Execute. Then, click on Map Range. You should see write added to the current mapped range.

Click Close.

$13.$ Set a break point on the done B done instruction $($line $34).$

$14.$ Down in the bottom right of the Keil Simulator window, click on the Memory $1$ tab and enter $0$

as the Address at the top. This window shows you everything that has been put in memory, both

instructions and data. The starting address of the line is followed by a colon and then each byte

separated by a space. Red indicates that a data item has been read and green indicates that a

data item has been written.

$15.$ Run the program and answer the following questions:

Part B

$1.$ What is the value of the PC $($decimal and hexadecimal$)$ when the program ends execution?

$2.$ What are the memory addresses associated with x$?$

$3.$ What are the memory addresses associated with y$?$

$4.$ What values are stored in y $($decimal and hexadecimal$)?$

$5.$ Are they correct
