Cache Miss Count: Variable size 1D array sequential access with direct-mapped cache For a 4KB, direct-mapped cache with 16-byte blocks, consider the following code snippet.
#define SIZE 1490
short A[SIZE]; //
short is 2B short total = 0;
for (int i = 0; i < 10; i++){
for (int j = 0; j < SIZE ; j++) {
total += A[j];
}
}
Only array A is stored in memory, and all other variables are register allocated. A is stored starting at address 0x450E000. The cache uses a Least Recently Used replacement policy. Note: The memory is byte addressable as always and data is stored in row-major order. Assume that the cache is initially empty.
(a) Calculate the number of misses for array A.
Number of Misses: number (rtol=0.05, atol=1e-08)
(b) Calculate the number of misses for array A if SIZE = 10990.
Number of Misses: number (rtol=0.05, atol=1e-08)
(c) Calculate the number of misses for array A if SIZE = 3230.
Number of Misses: number (rtol=0.05, atol=1e-08)

We as humans write math expression in infix notation, e.g. 5 + 2 (the operators are written in-between the operands). in a computer’s language, however, it is preferred to have the operators on the right side of the operands, i.e. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix.write a program that takes an “infix” expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % (example infix expression: (7 - 3) / (2 + 2)postfix expression: 7 3 - 2 2 + /result: 1guidelines: 1. you will need to use stacks in three placesa. one for the parenthesis check [char stack]b. one during infix to postfix [char stack]c. one during evaluation [int stack]for a and b above, you can use same array and same push, pop method as both ofthem are char. but for evaluation you have int stack and you might consider to createanother push pop method to handle it. maybe push_int, pop_int, etc. or find otherstrategy to utilize existing push pop method2. you can create a function for obtaining operator priority. that function should take anoperator as input and return its priority as an integer. this function will you a lot andreduce repeated code3. during evaluation you will need to convert char into integer. example for single digit: char c = '5'; int x = c - '0';
