Answer the following questions based on the schematic below.

1. How many registers are in the register file and what is the size, in bits, of each?
2. How many read ports and how many write ports does the register file have?
3. Suppose you need to have the value of register 2 on the 'b' input to the ALU. What signal(s) control this and what do their values need to be?

ALU Register File R_destination(1:0) - R_addr_a R_data_a R_source(1:0) - R_addr_b R_data_b Output_A[7:0] Output_B[7:0] a F 0 1 W_data W_addr W_enable R_destination(1:0) - '1' b Input[7:0) use_input Opcode(2:0)
