Question

Write a program that compares three unsigned 16 -bit values \( (v 1, v 2 \), and \( v 3) \) and move the smallest of them to AX. - Show the status of the flags and registers.

Answer 1

The question requires writing an assembly language program that compares three unsigned 16-bit values and moves the smallest to AX, as well as explaining the likely status of the processor's flags and registers.

Step-by-step explanation:

The question asks to write a program that compares three unsigned 16-bit values (v1, v2, and v3) and moves the smallest value into the AX register. Additionally, the question requests that we show the status of the flags and registers after this operation.

To accomplish this task, we would need to write a series of assembly language instructions that perform the comparison and then conditionally move the smallest value into AX. Without specifying the assembly language or the processor architecture being used, a pseudo-code example is provided:

• Compare v1 with v2
• If v1 is smaller, compare v1 with v3
• If v1 is also smaller than v3, move v1 into AX
• If v2 is smaller or equal to v1, compare it with v3
• If v2 is also smaller than v3, move v2 into AX
• If neither condition is true, move v3 into AX

The status of the flags (zero flag, carry flag, etc.) would depend on the outcomes of the comparisons performed during the execution of the program. The value of the AX register after the execution would contain the smallest value among v1, v2, and v3.
