Advice to Candidates 1.   You should attempt ALL requested parts.   2.   You should write your answers clearly.  Basic notions:  The aim of the questions in this part is to evaluate the required minimal student knowledge and skills.  Answers in the pass category represent the minimum understanding of basic concepts of IA-32 Processor Architecture,  Assembly Language Fundamentals: Instructions, Directives, Identifiers, Defining Data, Symbolic Constants, Data Transfers,  Addressing, and Arithmetic instructions. Question 1 Multiple Choices (8 marks)   Identify the choice that best completes the statement or answers the question. 1.   An assembly language program is translated  to machine code by a) an assembler c) a compiler  b) an interpreter d) a linker 2.   The 8086/8088 used two processing logical units  which were known as: a)   Segment and Offset Units    b) Bus Interface Unit and Execution Unit   c) Bus Unit and Execution Interface Unit d) ALU and Control Unit 3.   Real-address mode  can be used to access how much memory? a) 1 megabyte c) 2 megabytes  b) 1 gigabyte d) 2 gigabytes 4.   If CS = 0701H , SS = 0801H , SI = 0100H  and IP = 0108H  the address of the next instruction is: a) 07090H c) 07110H  b) 07811H d) 07118H 5.   The first processor that includes Virtual Memory  in the Intel microprocessor family was: a) 4004 c) Pentium Pro  b) 80286 d) 80486 6.   Given the following array definition, which letter choice contains a valid constant declaration named  ArrayCount  that automatically calculates the number of elements in the array? newArray DWORD 10,20,30,40,50 a) ArrayCount = ($ - newArray) / 4  b) ArrayCount = ($ - newArray) / 2 c) ArrayCount = (newArray -$ ) / 4 d) ArrayCount = (newArray -$ ) / 2 7.   Which of the following defines a constant Max? a) Max db 80 c) mov Max, 80  b) Max equ 80 d) Max dw 80 8.   Which of the following, when used in the data section of a MASM program, reserves 40 bytes of RAM  (memory)? a) BYTE 20 DUP (2) c) BYTE 20 DUP (20)  b) WORD 40 DUP (1) d) WORD 20 DUP (2)  2  Question 2  (3 marks)   Describe the typical uses for each of the following registers. Register Typical Uses   EAX EDX ESP ESI EIP EFLAGS  Familiar and Unfamiliar problems solving: the aim of the questions in this part is to evaluate that the student has some basic knowledge of the key aspects of the lecture material and can attempt to solve familiar and unfamiliar problems of IA-32 Processor Architecture, Assembly Language Fundamentals: Instructions, Directives, Identifiers, Defining Data, Symbolic Constants, Data Transfers, Addressing, and Arithmetic instructions. Question 3  (2 marks) If the content of the register SS = 3500H  and the content of the register SP= FFFEH, then   a)   Calculate the physical  address.   Solution b)   Calculate the lower range  of the stack. Solution c)   Calculate the upper range  of the stack segment. Solution d)   Show the logical address  of the stack. Solution  3  Question 4  (2 marks)   Write assembly code to do the following a)   Declare a byte containing the value 64 . Label the memory location “ var  ”.   Solution b)   Declare an unlabeled  byte initialized to 10 . Solution c)   Declare 10 uninitialized  bytes starting at the address label “ bytes ”. Solution d)   Declare three 4-byte words  of memory starting at; address “ Z ”, and initialized to 1, 2 , and 3 , respectively. Solution Question 5   Write complete assembly program that computes   the following equations   (5 marks)   and In your code: ã   Define the 2-byte signed integer   variables J , K  and L . ( ; Initialize J to 3 and K to -2 ) ã   Define the 2-byte unsigned integer   variables U1, U2  and U3 . ( ; Initialize U1 to 254 and U2 to 22 ) ã   DS  must point to the segment   address.   Solution Good Luck
