Question

A digital computer has a common bus system for 16 registers of 32 bits each.
The bus is constructed with multiplexers.
(i) How many selection inputs are there in each multiplier?
(ii) What sizes of multiplexers are needed?
(iii) How many multiplexers are there in the bus?

Answer 1

The following data is given. 16 registers of 32 bits universal bus system

a) How many selection inputs are there in each multiplier?

The bus is constructed with multiplexers.

Therefore we have a universal bus system of  32 line.  16 registers are equal to 2*4 registers therefore 4 selection inputs are there in each multiplier.

b)What are the sizes of multiplexers needed?

ANS:- sizes of multiplexers are needed are a 32X1 multiplexer  

(c)How many multiplexers are there in the bus?

Ans:- On the bus, there are 16 multiplexers
