Bus Implementation by using Mux and Instate Buffer


By on 04:28

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
