Lab Description $-$ Part I

Consider the hypothetical processor with instruction format seen below:

$0$

$34$

For the new opcodes $0011$ and $0111,$ the address field in the instruction refers to some

external I$/$O device. Show the execution for a program that does the following:

Load AC from device $5($address $705).$

Add contents of memory location $305.$

Store AC to device $6($address $706).$

In your answer, it is enough to show the contents of the registers at each step. The initial

state of the CPU, in the same format we saw in class, can be seen in the first fetch stage on

the next page. You must fill in the memory and register values for this initial fetch stage and

all remaining instruction cycles. Use Hexadecimal digits when filling in the stages. FILL IN THE TABLE
