Exercise 1:

1.     //The max function the max between a and b, it returns a if a == //b

public double max(double a, double b);  

2.     //The mult function returns the result of a * b public double mult(double a, double b);

3.     //The exist in array function returns the index of the element //‘a’ if //‘a’ exist in array ‘arr’ otherwise returns ‘-1’ public int existsInArray(int [] arr, int a);

4.     //Are array equals method compares two arrays and returns true // if the elements of array ‘a’ are equal to elements of array

// ‘b’, element by element. If equals it returns 0, it returns -

// 1 if not

public int areArrayEquals(int [] a, int [] b);

Consider a computer with the following characteristics: total of 256Mbyte of main memory; block size of 8 bytes; and cache size of 128 Kbytes.

i. Design a direct-mapping address structure.

ii. Design an associative-mapping address structure.

iii. Design a two-way set-associative-mapping address structure.

iv. For the main memory addresses of F0010ABH, F012356H, and 00CABBEH, give the corresponding tag, cache line address, and word offsets for a direct-mapped cache.

v. For the main memory addresses of F0010ABH, F012356H, and 00CABBEH, give the corresponding tag and offset values for a fully-associative cache.

vi. For the main memory addresses of F0010ABH, F012356H, and 00CABBEH, give the corresponding tag, cache set, and word offset values for a two-way set-associative cache.
