Total Marks: 10 Due Date: 14-11-2016

Please carefully read the following instructions before attempting assignment.

RULES FOR MARKING

It should be clear that your assignment would not get any credit if:

• The submitted assignment does not open or file is corrupt.
• Strict action will be taken if submitted solution is copied from any other student or from the internet.

You should consult the recommended books to clarify your concepts as handouts are not sufficient.

You are supposed to submit your assignment in .doc or docx format.

Any other formats like scan images, PDF, zip, rar, ppt and bmp etc will not be accepted.

Topic Covered:

·         Registers

·         Intel Architecture

·         Register Architecture

·         Data Declaration

·         Addressing Modes

NOTE

No assignment will be accepted after the due date via email in any case (whether it is the case of load shedding or internet malfunctioning etc.). Hence refrain from uploading assignment in the last hour of deadline. It is recommended to upload solution file at least two days before its closing date.

If you people find any mistake or confusion in assignment (Question statement), please consult with your instructor before the deadline. After the deadline no queries will be entertained in this regard.

For any query, feel free to email at:  CS401@vu.edu.pk

Questions No 01                                                                               10 marks

Write a complete assembly language code for the following pseudo code:

Initialize a variable named “NUM1” with “04 as a Hexadecimal Number”

Initialize a variable named “NUM2” with “08 as a Hexadecimal Number”

Initialize a variable named “NUM3” with “12 as a Hexadecimal Number”

Initialize a variable named “NUM4” with “00 as a Hexadecimal Number”

Initialize AX with zero “0”

Initialize BX with zero “0”

Move NUM1 into AX

Move NUM2 into BX

Add BX into AX

Move NUM3 into BX

Add BX into AX

Store AX into NUM4

Questions No 02                                                                               10 marks

Suppose, we have the following register values:

AX	0150
BX	AB5D
CX	FF0A
DX	1234
DS	CC20
CS	EF10
ES	225F
SS	E25F
SI	1212
SP	CD0F
BP	95F8
DI	BDEF

You are required to calculate the physical address generated by each of the following instructions.

1.      ADD [bx+Di], CX

2.      MOV DX, [SP+1652H]

Note: Each provided instruction is independent.
