Homework Answers
a)
Immediate addressing mode..
Load 3000 will store AX into 3000
AX becomes 3000
--------------------------------------------------------------------------------------------------------------------------------------------
b)
Direct addressing mode...
It stores the data value where at location 3000
So at address 3000, the value is 7000
So AX becomes 7000
------------------------------------------------------------------------------------------------------------------------------------------------------
c)
Indirect addressing mode ...
LD AX [3000]
At 3000 address we have value 7000
So accumulator stores value at address 7000
So AX becomes 8000
-------------------------------------------------------------------------------------------------------------------------------------------------------
d)
Indexed addressing mode ...
Here AX is stored on address + offset
Load AX , 3000 + 5000
Load AX, 8000
So AX becomes 3000

This question is from Computer architecture. Please show steps and add comments so its easy to understand. Translate the high-level language code below into assembly instructions. The variables A, B, C, D, E and F are located in the memory and can be accessed by their label (e.g., LOAD R1, A will load A from the memory into R1). Minimize the number of instructions in the assembly code that you write. F = (A-B)*(C+D)/(E-D) a) Write the code for an...

Question 20 5 pts Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. How many bits can be used for the memory address? Question 21 5 pts Suppose we have...

Questions1. The function L is defined as L(1) = 2,L(2) = 1,L(3) = 3,L(4) = 4 and for n ≥ 4,L(n + 1) = L(n) + L(n − 1) + L(n − 2)L(n − 3)i.e., the (n + 1)-th value is given by the sum of the n-th, n − 1-th and n − 2-th values divided by the n − 3-th value.(a) Write an assembly program for computing the k-th value L(k), where k is an integer bigger than...

The Fibonacci sequence F is defined as F(1) = F(2) = 1 and for n>= 2, F(n + 1) = F(n) + F(n − 1) i.e., the (n + 1)th value is given by the sum of the nth value and the (n − 1)th value. 1.
