Answer :
To perform multiplication operations using ARM Cortex and Keil uVision5, you can write assembly code using the ARM assembly language and assemble it using the uVision5 IDE.
Here's an example of how you can multiply two numbers and store the result in a register:
```assembly
AREA Multiply, CODE, READONLY
EXPORT __main
ENTRY
__main
MOV R0, #0x25 ; Load the first number (0x25) into R0
MOV R1, #0x69 ; Load the second number (0x69) into R1
MUL R2, R0, R1 ; Multiply R0 and R1, store the result in R2
; You can choose to store the result in memory or display it
; Store the result in memory
STR R2, [R3] ; Store the result in a memory location
; Or display the result
MOV R7, #4 ; System call for printing
MOV R0, #1 ; File descriptor for standard output
LDR R1, =result_string ; Load the address of the string
LDR R2, =4 ; Length of the string
SWI 0x123456 ; Call the SWI instruction to trigger the print
END
In the above code, we load the values `0x25` and `0x69` into registers R0 and R1, respectively. Then, we use the `MUL` instruction to multiply the two values and store the result in register R2.
To check if your answer is correct, you can run the assembled program in the Keil uVision5 simulator and inspect the value in register R2.
For multiplying larger numbers like 100000 and 150000, you can follow a similar approach by loading the values into appropriate registers and using the `MUL` instruction. Remember to use the appropriate register width to handle larger numbers.
