Design a 3-bit Arithmetic Logic Unit (ALU) with six micro-operations. Note: when answering the below questions, optimize your solution by reducing the number of logic gates used. 1) Complete the table below by showing the select input bits and the necessary groupings (5 points) Select Inputs Micro-Operation D-A+Y+Cin Add Add with carry Decrement A by 3 Decrement A by 2 Selective complement the most significant bit of A Mask the least two significant bits of A 2) Draw a detailed logic circuit of the ALU's arithmetic unit (10 points) 3) Draw a detailed logic circuit of the ALU's Logic unit (10 points) Do not Answer here. All your exam solutions should be submitted as a single PDF file at the end. BIE Design a 3-bit Arithmetic Logic Unit (ALU) with six micro-operations.
