Optimizing cache performance improves application speed. Understanding cache hierarchy is essential for this. Locality of reference helps utilize cache effectively. You can reorganize data structures for better cache performance. Here’s an example:
“`cpp
#include
using namespace std;
const int SIZE = 1000;
void process(int arr[SIZE]) {
for (int i = 0; i < SIZE; i++) {
arr[i] *= 2; // Simple operation
}
}
int main() {
int data[SIZE];
process(data);
return 0;
}
```
In this code, iterating through contiguous memory helps cache hits. Reorganizing loops can further enhance cache efficiency.
