Using Caches
1)Create a function that takes in a long long
int representing a memory address and parses into the
components Tag, Index, and Offset. The function

Answer 1

Sure! Here's an example implementation in C language:

```c

#include <stdio.h>

typedef struct {

unsigned long long tag;

unsigned long long index;

unsigned long long offset;

} CacheComponents;

void parseMemoryAddress(unsigned long long address, CacheComponents* components) {

unsigned long long offsetBits = 4; // number of bits for offset

unsigned long long indexBits = 8; // number of bits for index

unsigned long long offsetMask = (1 << offsetBits) - 1;

unsigned long long indexMask = ((1 << indexBits) - 1) << offsetBits;

components->offset = address & offsetMask;

components->index = (address & indexMask) >> offsetBits;

components->tag = address >> (offsetBits + indexBits);

}

int main() {

unsigned long long memoryAddress = 0xABCD1234; // example memory address

CacheComponents components;

parseMemoryAddress(memoryAddress, &components);

printf("Tag: %llx\\", components.tag);

printf("Index: %llx\\", components.index);

printf("Offset: %llx\\", components.offset);

return 0;

}

```

This code defines a structure `CacheComponents` to hold the tag, index, and offset of a memory address. The function `parseMemoryAddress` takes a memory address and extracts the tag, index, and offset using bit masking and shifting operations. The `main` function demonstrates the usage by passing a sample memory address and printing the extracted components.

Note that the example uses 4 bits for the offset and 8 bits for the index. You can adjust these values according to your specific cache design.
