1. Encode the following instruction: Add Sto, $t1, $t2 Assume: op field -0; funct 32; registers $s0-$s7 map onto registers 16 to 23; and Registers St0 to $t7 map onto 8 to 15. 2. Suppose that the INTEL Processor has the following data: SS-1000H, DS-2000H, BP=1000H, BX= 0300H and DI-0400H. Determine the memory address accessed by each of the following instructions, assuming real mode operation: (Suffix of H means hexadecimal) a) MOV AL, [1OFOH b) MOV [BP-DI+FFF9H), AI
