ANSWER ALL QUESTIONS

Question 1

A block of memory contains 50 random words of data. Assume that the values are in

two’s complement representations and are stored in the R/W memory area. You need

to provide the 50 random words and to include them in an initialization file: assign2.ini.

Write a program using the ARM assembly programming language to do the following:

1. a) You are required to reverse the word order in a block of 50 random words (Hint:

the last word stored in the memory becomes the first and vice versa).

1. b) Next, find the minimum and maximum value in the 50 random words of data.

 

Question 2

1. a) Write a subroutine using the ARM assembly programming language to construct

tables of 20 (n = 0, 1, 2, …, 19) 32-bit data. There are 2 inputs to the subroutine.

One is an option and the other is the starting address of the table to be constructed.

There are 2 possible options: 1 or 2. This option will dictate how you should

construct the table. This is shown as followed:

 

option = 1: Build a table of an arithmetic sequence numbers. This sequence has

a difference of 3 between each number. The pattern is continued by

adding 3 to the last number each time, like this: 1, 4, 7, 10, 13, 16,

19, 22, 25, ... Assume that the first number is 1.

 

option = 2: Build a table of a geometric sequence numbers. This sequence has

a factor of 3 between each number. The pattern is continued by

multiplying by 3 to the last number, like this: 1, 3, 9, 27, 81, 243, ...

Assume that the first number is 1.

1. b) Write the main program using the ARM assembly programming language to call

the subroutine written in part (2a). The main program needs to provide the 2 inputs

to the subroutine: an option and the starting address of the table to be constructed.

Hint: you need to use the key concepts of table generation, jump table and subroutine.
