Write a program using only the following MIPS instructions: The memory reference instructions load word (lw) and store word (sw) The arithmetic-logical instructions add, sub, AND, OR, and sit The instructions branch equal (beq) and jump (j). These instructions are the same basic instructions explained in class, these are used in the design of any basic processor. Run your MIPS assembly program using the simulator (MARS) and the MIPS X-ray for the animation of the MIPS datapath. You will find the MIPS X-ray under the tools tab. Run your program step by step and explain what is happening. In the X-ray is displayed the instruction that is under execution and the bits corresponding to that instruction.

This will display another window and give you a more detailed datapath for the instruction that is currently running. These are representations of the hardware and circuits in a processor and how the instructions execute in it.

Explain what the iTLB multi hit vulnerability is about, and how the split of huge pages helps in the mitigation of that vulnerability. 2. Explain about the L1TF vulnerability and about the 3 techniques used to mitigate it: a. PTE Inversion; b. VMX conditional cache flushes, c. SMT disabled
