1. What is the difference between Program Counter and $zero. In case of 16-bit and 128-bit architecture, what would be the increment in memory address for sequential instruction execution. [2] 2. Let us consider the instruction lw $4, X($5). Now, suppose we have an array A and the base address of that array is 256 in decimal. If we are looking to load the contents of A[5], find the value of X in the Iw instruction in case of 256-bit architecture. [1] 3. Assume that the base address of the array A is in $s0, and the values of i and f are stored in $s1 and $s2. Then translate the following statement into MIPS assembly code. Assume that A is a byte array and f and i are 32-bit integers. [1] f=a[i] 4. Let us consider the set of instructions given below. Here, X and Y are in registers $s0 and $s1 respectively. Base address of the array Arr is in register $s4. Now, write the equivalent MIPS code for the given set of instructions, identify the instruction type and write the machine code for each instruction. [4.5] X=15Y-5; Arr[5] = 2X+Arr[10]; 1. What is the difference between Program Counter and $zero.
