Using Logisim, build a 1 bit ALU with the following two control inputs, three data inputs, A, B and Cin, and two outputs O for the function output,...

A AND B

 0   1    A OR B 1   0    NOT B 1   1    A + B 

Embed your 1-bit ALU into a package, and chain 4 together to form an 4 bit ALU module. (The video should give you guidance on how to do this.)  Inputs from A and B will come from 4-bit registers, and the output will go into a 4-bit register. 

Additionally there should be a 4-bit STATUS register with bit 0 being C (the carry flag), bit 1 being V (the overflow flag), bit 2 being N (the sign flag) and bit 3 being Z (the zero flag.)
