thank you

In the following problem sets, we will use this expanded set of opcodes for our hypothetical machine: 0001 = Load AC from memory (LOAD) 0010 = Store AC to memory (STORE) I 0100 = Subtract memory from AC (result in AC) (SUB) 0101 = Add to AC from memory (result in AC) (ADD) 0110 = Jump to address, absolute jump (JMP) 0111 = Jump to address if result was 0, conditional jump (JMPZ) 1000 = Jump to address if result was negative, conditional jump (JMPN) CPU registers Memory 5941 Memory CPU registers 300 PC 300 5941 PC 301 2940 AC 301 2940 AC 302 6300 IR 302 6300 IR 940 940 941 Fetch 3 941 Execute 3 CPU registers CPU registers Memory 5941 Memory 5941 300 PC 300 PC 301 2940 AC 301 AC 2940 6300 302 6300 IR 302 IR 940 941 940 941 Execute 4 Fetch 4
