You are now able to Build a $2-$bit CPU by expanding the $1-$bit CPU described in the lab notes.

Remember to have a $2-$bit bus for your design.

The $2-$bit CPU will do the following operations:

For instruction $00,$ do $2-$bit XOR, test $10$ XOR $11=01$

For instruction $01,$ do $2-$bit AND, test $10$ AND $11=10$

For instruction $10,$ do $2-$bit NOT operation, the Operand will be in the register ACC, test NOT $10=01.$

For instruction $11,$ do $2-$bit OR$,$ test $10$ OR $11=11$
