How many multiplexers will be required to construct a bus of 16 registers of 16 bits?

If there are 8 registers of 16 bits each, then we need 16 multiplexers, each of which is an 8 : 1 multiplexer to create the 16 bit data bus.

How many selection lines are there in common bus for 32 registers of 16 bits each?

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.

How many multiplexers are there in the bus?

The bus consists of 4×1 multiplexers with 4 inputs and 1 output and 4 registers with bits numbered 0 to 3. There are 2 select inputs S0 and S1 which are connected to the select inputs of the multiplexers.

How many multiplexers are there in the A bus and what is the size of each multiplexers?

The size of each multiplexer must be 'k * 1' since it multiplexes 'k' data lines. For instance, a common bus for eight registers of 16 bits each requires 16 multiplexers, one for each line in the bus.

What is common bus system?

The basic computer has eight registers, a memory unit, and a control unit . Paths must be provided to transfer information from one register to another and between memory and registers. The outputs of seven registers and memory are connected to the common bus. ...

How a common bus system can be constructed?

A bus can be constructed using multiplexer which enable a sets of registers to share a common bus for data transfer. The select lines S1 and S0 indicate which of four register will have its contents transferred to the bus.

How many bits are there in the register code part?

How many bits are there in operation code, the register code part and the address part ? OP-code 32 – 1 – 18 – 6 bits = 7 bits. Option (C) is correct.

How many selection lines are there in each multiplexer?

We know that 8x1 Multiplexer has 8 data inputs, 3 selection lines and one output. Whereas, 16x1 Multiplexer has 16 data inputs, 4 selection lines and one output.

How many selection inputs are needed for MUX A and MUX B?

For MUX A, the number of selection inputs are needed is four, to select one of the selection register. For MUX B, the number of selection inputs are needed is four, to select one of the selection register.

What size are multiplexers?

Multiplexer Sizes

1. has four inputs and one output, so it is referred to as a 4:1 (4 to 1) mux. There are many other common multiplexer sizes, including 2:1 (with 1 select input), 8:1 (with 3 select inputs), and so on. If you know how many selection inputs a mux has, you can calculate the number of data inputs.

What sizes of multiplexers are needed?

(ii) What size of multiplexers is needed? size of multiplexers= Total number of register X 1 = 16 X 1 Multiplexer of 16 x 1 size is needed to design the above defined common bus.

What is the need of common bus design a bus with 4 register with 8 bit each?

Common Bus System (4-bit, 8-bit)

Generally, computers use many registers for different purposes. We need to transfer the data and instruction between these registers. So, To transfers the data between the registers, the common bus system is used .

What is the size of the common bus connecting the different registers?

Various Registers:

4 registers DR, AC, IR and TR have 16 bits and 2 registers AR and PC have 12 bits.

What is buses in COA?

In computer architecture, a bus (shortened form of the Latin omnibus, and historically also called data highway) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.)
