We are trying to design a Register File for our CPU and we had decided to include 8 registers in the Register File and each register is 4-bit. (this is different from MIPS, which has 32 registers and each has 32-bit) a) Design the 4-bit register using D flip-flops and logic gates, so that it can hold the 4-bit daia :31o when the inpui EN is 0. When EN is 1e reiter will be reloaded wit.h input values 131211lo at the rising edge of CLK. Please draw your circuits. b) Now the Control Unit from our CPU has send in a 3-bit input which has identified the register that will store the 4-bit output value from the Function Unit. Design your Register
