Bus can be implemented through Mux and instate buffer.Firstly I discuss Bus Implementation by using Mux.

Table:-

S(1)	S(0)	Register
0	0	Reg A
0	1	Reg B
1	0	Reg C
1	1	Reg D

Point to remember:-
                                       
                     No. of Mux=No. of Register    
                     Size of Mux=No. of Register 

In above diagram we using 4 mux and 4 register(reg1,reg2,reg3,reg4).

Bus Implementation using Instate buffer:-

Table:-

S(1)	S(0)	D(0)	D(1)	D(2)	D(3)
0	0	1	0	0	0
0	1	0	1	0	0
1	0	0	0	1	0
1	1	0	0	0	1
