ARM assembly language_Project 10 Solution

Computer Project #10
Assignment Overview
This assignment develops familiarity withdata structuresin assemblylanguage. You will developa set of ARM assembly languagefunctionsto complete a program which manages student statistics.
It is worth50 points (5% of course grade) and must be completed no later than 11:59 PM on Thursday,12/1.
Assignment Deliverables
The deliverablesfor this assignmentarethe following files:
proj10.makefile –themakefile which produces "proj10" proj10.support.s –the source code for yoursupport module
Be sure to use the specified file names and to submit themfor grading via theCSEhandin system.
Assignment Specifications
The program willuse an ordered table to maintain the data set, whereeach student's identification number will serve as a unique key to identifythat student. The capacity of the ordered table will be determined when it is created.
1. The instructor-supplied driver module(function "main" and associatedfunctions) will perform all input and output, and will manage the overalloperation of the program.
2. You will supply the functions whose declarations are listed below:
int search( struct table*, unsigned long, struct student** ); int delete( struct table*, unsigned long ); int insert( struct table*, unsigned long, char*, int, int, int );
Thosethreefunctions (and any "helper" functions which you develop) will constitute a module named "proj10.support.s".
Assignment Notes
1. The functions in your support module must be hand-writtenARMassemblylanguage functions (you may not submit compiler-generated assembly languagefunctions).
2. The file "project10.support.h" (appended below) includes all relevantdeclarations, along with descriptive comments.
3. The file "project10.driver.o" containsthe instructor-supplied drivermodule.
4. The file "project10.data" contains a sample data set. Your program mustfunction correctly for that sample data set, aswell as any other properlyformatted data set.
5. You may wish to create stubs for the required functions, then translate, link and execute the program to explore the behavior of the driver module.
