please sketch the solution no coding

2. Study section 6.5 of Lee's text and assume Fig. 6-21 is a 64bit ALU using 64 1-bit full adder (1BFA). 1. Are all 1BFAs configured the same way to achieve functions specified in Table 6-2? 2. What's the purpose of the zero-extend box? 3. Modify Fig. 6-21 so that the ALU is capable of completing all functions, at a given time, as incoming channels into the bottom mux. 3. Using the multiplication algorithm discussed in class, multiply two 6-bit unsigned integers 87. Show register updates for all steps. Clearly label your registers. 4. Similar to question \# 3, perform 39/6
