MIPS R2000 Project

I have an assembly language assignment that needs to be original. Need it done in 2 days. Deadline is June 8, 6:00am in Vietnam. Sorry for such short notice, but it is fairly simple.

The goal of the project is to write a MIPS program that implements the algorithm SELECT, that returns

an order statistic of a list. The i-th order statistic of a list of numbers is the i-th smallest number in

that list. The minimum, maximum and median of a list of integers are in fact order statistics. For example,

given a list of n numbers, the minimum is the 1st order statistic and the maximum is the n-th order statistic.

SELECT nds the i-th smallest number (a.k.a, the i-th order statistic) without sorting the list of numbers.

The details of SELECT, which must be adhered to in your implementation (including the recursion), will

follow in Section 2.

In our version of SELECT, we will rst build what is called a linked list. A linked list is a chain of

nodes. Each node has at least two members: one which holds data and the other which points to the next

node in the list. Figure 1 shows an example of a linked list. The linked list structure will serve us in two

ways in our implementation of the SELECT algorithm:

 the ease of appending new nodes to the list (the program user can keep inputting numbers)

 the ease of splitting a linked list in two (you may nd this very helpful in implementing the SELECT


Sample Output

Specify i (for an order statistic): 5

Enter number: 12

Enter number: 99

Enter number: 32

Enter number: 12

Enter number: 19

Enter number: 37

Enter number: 32

Enter number: 0

7 numbers were entered and the i-th smallest is 32.


1. Function Descriptions

You must implement the following ve procedures in assembly language. Please note that some of these

functions call others.

void main()

struct node* root_node(int value)

struct node* append_node(struct node* conductor, int val)

int* allocate_memory(int numberofbytes)

int select(struct node* root, int i)

(a) void main() Please assume that your program receives the valid input described below.

 main() will prompt the user to specify an order statistic.

 main() will then prompt the user for positive integer values until 0 is entered.

 main() will call root node() and append node() in order to build a linked list from the


 main() will call select() to determine the order statistic.

(b) struct node* root node(int value)

 This function calls allocate memory() to allocate memory for a node.

 This function creates the rst node of a linked list with the rst input value and a pointer to

0 (i.e. null).

 This function returns the address of the root node.

(c) void append node(struct node* conductor, int val)

 This function calls allocate memory() to allocate memory for a node.

 This function takes the root node of a linked list as input and appends a new node with the

value val to the end of the linked list.

(d) int* allocate memory(int numberofbytes)

 This function takes the number of bytes to be allocated as its argument.

 This function increments the pointer to the heap by the number of bytes allocated.

 This function returns the address of the block of memory allocated.

(e) int select(struct node* root, int i)

 This function takes the address of the rst node in a linked list and a positive integer i.

 This function returns the i-th order statistic in this list.

I will post the instruction and a written format for you. Please follow the instruction, remember, you must implement 5 procedure i mentioned above.<`>PLUS, for my generous and kindly nature, ^ ^ one of the function has already been written to you.
