ALU Design Question - Computer Processors

Please answer correctly for thumbs up

27. Design a 4-bit ALU. The ALU will take two 4-bit wide buses as input, named a and b, and produce a 4-bit wide output bus called out. In addition the ALU should produce a flag bit, called zero, that indicates if out has the binary value 0. The ALU should have 2 control bits, the table below describes the boolean functions the control bits indicate Control Bit 0 Control Bit 1 Boolean function ??? -(? ??) av b (0 a V b) You may communicate your design in either HDL, as a block diagram, boolean formula or as a logic diagram. 27.
