in the following problem sets, we will use this expanded set of list of opcodes for our hypothetical machine: 0001 = Load AC from memory 0010 = Store AC to memory 0011 - Jump to address 0100 - Subtract memory from AC (result in AC) 0101 - Add to AC from memory (result in AC) Perform program fetch/execute cycles for the following initial memory and program states. NOTE: one of the problems uses the Jump to address instruction to implement a loop. You do not need to simulate more than the 4 fetch/execute cycles for this problem, even though the program in principle would execute forever.
