1. Write a program to compare two numbers and store the largest number in R5



List1 DCB 0x34



List2 DCB 0x25



2. Write a program to read memory location list and clear bit position b3b2 and b1



List DCW 0x5F

Answer :

The specific assembly language and syntax may vary depending on the architecture and assembler being used. The provided program assumes an ARM-like assembly language.

Here's an example program in assembly language that compares two numbers and stores the largest number in register R5:

LDR R1, List1 ; Load the value from List1 into register R1

LDR R2, List2 ; Load the value from List2 into register R2

CMP R1, R2 ; Compare the values in R1 and R2

MOVGT R5, R1 ; Move the value in R1 to R5 if R1 is greater than R2

MOVLE R5, R2 ; Move the value in R2 to R5 if R2 is greater than or equal to R1

; Rest of the program...

List1 DCB 0x34 ; Define a byte variable List1 with value 0x34

List2 DCB 0x25 ; Define a byte variable List2 with value 0x25

In this program, we load the values from List1 and List2 into registers R1 and R2, respectively. We then compare the values using the CMP instruction. If the value in R1 is greater than the value in R2 (indicated by the GT condition), we move the value from R1 to R5 using the MOVGT instruction. Otherwise, if the value in R2 is greater than or equal to the value in R1 (indicated by the LE condition), we move the value from R2 to R5 using the MOVLE instruction.

Please note that the specific assembly language and syntax may vary depending on the architecture and assembler being used. The provided program assumes an ARM-like assembly language.
