Assignment: your first simple program
In this assignment you will be asked to write your first assembly program. You will have to use the knowledge you acquired from assignment 0 in order to complete this task, so make sure you have a thorough understanding of the example program. Remember that you can always ask the lab course assistants for help. For this program, you will not have to write any specifications, since there is no significant algorithmic complexity involved. However, you are of course required to write proper comments.
In order to complete this assignment you will need to call the printf subroutine. Paragraph 3.3.1 of the reference section explains the details of calling subroutines and paragraph 3.4.1 explains how to use the printf subroutine. Section 3.1 explains the commands that you will need to enter on your shell in order to build and run your program.
Exercise:
Create a new text file, called "hello.s". Implement a simple "main" routine that exits the program immediately with the proper exit code and without crashing. Build your program and run it. Alter your main routine in such a way that it prints a message containing your names, study numbers and the name of the assignment on the terminal. You should not need more than one call to printf to display your message. After completing the rest of the exercises in part 1, you will need to have the source code of this program checked by the teaching assistants, so make sure you keep all your files in order.
For this problem you will find all the prime numbers between 2 and N inclusive. A number is prime if it is only evenly divisible by itself and 1.
Write an assembly language function int toInches(int feet) that accepts a length written in feet as an argument and returns this length written in inches.
Write a header comment block at the top of the source code file in the format shown on the next page. Make sure to put both author's names in the header comment block if you worked with a partner.
Devise an addressing mechanism that allows an arbitrary set of 64 addresses, not nec- essarily contiguous, in a large address space to be specifiable in a 6-bit field. Give a disadvantage of self-modifying code that was not mentioned in the text..
Write a set of assembly codes in uVision that performs the function described below. Begin with the assumption that 10 randomly selected integer numbers (data) are stored at 0x20002000 to 0x20002024 in sequence in the memory region.
Modify the single-cycle MIPS processor to implement one of the following instructions. Sec Appendix B for a definition of the instructions. Mark up a copy to indicate the changes to the datapath. Name any new control signals.
Create a program called YourLastName_assignment3.asm. This simple program will print the following information to the command prompt screen as well as take in user input and perform some basic computations.
