A four-way set associative cache consists of 32 slots. The main memory block size is 16 words. Consider referencing following word addresses 0, 1, 2, . . . , 287 repeatedly for 5 times. Assume that the cache is initially empty. How many times will the way prediction scheme not predict correctly? What if we first reference addresses 0, 1, 2, . . . , 143 repeatedly for 5 times first, then reference addresses 144, 145, . . . , 287 repeatedly for 5 times? Repeat the same computation

Write a program that uses a random number generator to generate a two digit positive integer and allows the user to perform one or more of the following operations: a. double the number. b. reverse the digits of the number. c. raise the number to the power of 2, 3, or 4. d. sum the digits of the number. e. if the number is a two-digit number, then raise the first digit to the power of the second digit. f. if the number is a three-digit number and the last digit is less than or equal to 4, then raise the first two digits to the power of the last digit. after performing an operation if the number is less than 10, add 10 to the number. also, after each operation determine if the number is prime. each successive operation should be performed on the number generated by the last operation. your program should not contain any global variables and each of these operations must be implemented by a separate function. also, your program should be menu driven. 7. (fraction calculator) write a program that
