Please show the steps of calculation. Thanks 1. Given the following state of the memory and registers (all values are decimal): Register Value Memory Value Address 255 778 779 780 R2 R3 R4 776 255 522 The following instructions are executed sequentially. Indicate the change in memory location/register after every instruction executes. 100 101 102 103 104 LD R4, 3 (R2) MUL R3, R3, R1 ADD R3, R3, #15 SD R3, 2 (R2) BR (700) 2. For each of the above instructions, construct a table showing what happens in each stage of the Fetch-Decode cycle.
