Greetings!!

Assume that the instructions are loaded at address 0x00400000.

0x00400000 CBZ X19,EXIT

0x00400004 ADD X10,X19,X20

0x00400008 exit address

1. Machine code for ADD X10,X19,X20:

The instruction format of ADD instruction is:

Fill those fields with the correponding bits gives:

Write the hex equivalent of each nibble:

Answer:1000 1011 0001 0100 0000 0010 0110 1010=8B14026A

2. Machine code for CBZ X1,EXIT:

The instruction format of CBZ instruction is:

Fill those fields with the correponding bits gives:

Please note that the 19 bit address is the offset address required for the address calculation. Address=PC+Offset

Write the hex equivalent of each nibble:

Answer:1011 0100 0000 0000 0000 0001 0001 0011=B4000113

Hope this helps
