Answer to Question #244731 in Electrical Engineering for shailesh

Question

3. Consider PC = 92

4. DR=312-01

5. Now perform the below given task

AR <- PC

M[AR] ->DR

IR<-M[AR]

Explain the contents of the memory after the execution of second instruction.

Answer 1

In the present case, we are provided with PC = 92

DR=312-01

Now perform the below given task

AR &lt;- PC

M[AR] -&gt;DR

IR&lt;-M[AR]

We understand the details of the provided instructions are as follows:

AR Í PC IR Í M[AR] b) There is no such access to AC except for INPR, DR and itself, so the

correct form would be: DR Í TR AC Í AC + DR

The memory after the execution of second instruction involve:

We will replace the memory reference instruction ISZ with [ LDC address ], which will load the

CTR register with the value specified by the address. In addition to that, we will add a new

register reference instruction.
