Hello sir, This is a simple question about an lmc simulator, can you solve it$?$

Computer architecture $[$Year $3]$

Online$/$ Remote practice questions

November $2022$

This is original program loader

$86$ LDA $98598//$ initialize the STORE instruction at loc. $92$

$87$ STO $92392//$ storing the contents of mailbox $98,$ that is $301$

$88$ INP $901//$ input a value

$89$ SUB $97297//$ subtract $999$

$90$ BRZ $01701//$ done loading$--$jump to $01$ for execution

$91$ ADD $97197//$ restore input value

$92$ DAT $00//$ store value. This will contain $3$XX$,$ with XX indexed

$93$ LDA $92592//$ load the STORE instruction in $92$

$94$ ADD $99199//$ increment it

$95$ STO $92392//$ and resave it

$96$ BRA $88688//$ continue with the next input

$97$ DAT $999999//$ value $999$ for testing

$98$ DAT $301301//$ initial STORE $01$ instruction as a data value

$99$ DAT $011//$ value $1$ for indexing

What you need to do

$1.$ Load the above program loader in the LMC$.$ The instructions should be loaded in your LMC at the mailboxes indicated above to work properly. Please make sure that in mailbox $00$ you have the instruction to branch to mailbox $86($first instruction of the program loader$).$

$2.$ Run the program loader and input the following user program which asks for $3$ nums, add the first $2$ nums $,$ and subtract $1$st num from $3$rd$,$ which means $3$rd num minus $1$st num. Also

Please convert to opcodes to enter instruction in lmc simulator, use peterhigginson lmc simulator

$00$ INP

$01$ STA $09$

$02$ INP

$03$ ADD $09$

$04$ OUT

$05$ INP

$06$ SUB $09$

$07$ OUT

$08$ HLT

$09$ DAT $00$

Please answer :

How do you do it$,$ how did you add a branch to mailbox $86$ in mailbox $00.$ Step by step process in lmc simulator required.

Second part:

This original program loader loads the user program starting at mailbox $01,$ you need to change this to load the user program starting at mailbox $30.$

So$,$ you have to make the code for the modified program loader that starts at mailbox $00$ and load the user program starting at mailbox $30$ and explain the changes.

Summary of final requirements $-$

How to run original code above with a user program to perform calculations. Please make sure that in mailbox $00$ you have the instruction to branch to mailbox $86($first instruction of the program loader$).$ Whole code needed.

Modified original code with steps to run it with a user program in the simulator. Move the program loader so that it starts at mailbox $00$ in the LMC$.$ Modify as required so it works properly. The original program loader loads the user program starting at mailbox $01,$ you need to change this to load the user program starting at mailbox $30.$

Please provide $-$ Full original code with user program and Full modified code with user program with steps to run it in simulator required in homework.
