Use tool 'MARS' to Solve the problem:

Download third.asm and macro.asm in a same directory.

Add the following macro in this macro.asm:

lwi ($reg, $ui, $li) : This macro takes two 16-bit immediate values $ui and $li and put them into higher bits and lower bits of $reg. For example lwi($s1, 0x5a5a, 0xa5a5) will place a value 0x5a5aa5a5 into $s1 register.

Assemble and execute third.asm. This should create following sample output Register S1 contains integer number 1515890085

============================================================

The given .asm document is as follow: macro.asm:

third.asm:

=================================================================

All the information are already shown above, just need help with the macro in macro.asm.

Please help, thank you!
