Question $4$

Create a $4-$bit "barrel shifter" that performs left shifts. Your design should be have $2$ control lines, meaning the $-$ shifter can perform left shifts of $0,1,2,$ or $3$ bits. Your design should include multiplexors for enabling or disabling shifts at different stages. See the "Additional Resources" at the top for information on barrel shifters.

Question $5$

Create a $4-$bit register capable of performing parallel load, left and right shift, and has a load control line. Use multiplexors and D$-$flip flops in your design.
