Now consider that we are executing one of these programs for the very first time. Assume we have a memory system with TLB, L1 I-cache, L1 Dcache, L2 cache and 2-level Page Table Virtual Memory system. List all the steps that will/may happen as we load instructions or data from memory. You will also need to list the steps taken when target instructions or data are not in cache or page tables. i.e. the steps to handle misses.

Load instructions: 1. Read instruction: check TLB if instruction is in memory by looking up its virtual page number.

2. If virtual page number is not present in TLB, read miss. Check L1 page table to see if virtual page number is present.

Load data: 1. ........
