Function of multiplexer in a processor?

A multiplexer (MUX) is a device that can receive multiple input signals and synthesize a single output signal in a recoverable manner for each input signal. ... What's more, a computer processor has several multiplexers to control the data and address buses.

What does a multiplexer do in CPU?

A multiplexer is a logic gates circuit used to fetch a bit of data from memory at a given memory address. A processor has several multiplexers (MUX) controlling the data and address buses. Multiplexers are switches allowing the processor to select data from multiple data sources.

What is the main function of a multiplexer?

The basic function of a multiplexer: combining multiple inputs into a single data stream. On the receiving side, a demultiplexer splits the single data stream into the original multiple signals.

What is multiplexing used for?

Multiplexing is widely used in telephony, data communications, and audio/video broadcasting. Telephone service typically use multiplexors to combine the various lines in a neighborhood into a single signal that is then carried to the central switching office for routing and call management.

How does multiplexer work?

A multiplexer is a system of multiple inputs and just one output to receive signals coming from multiple acquisition networks. The device transfers all input signals to a microprocessor, which receives and processes the data, transmits it to the output devices, and controls the system as a whole.

Is multiplexer a decoder or encoder?

The encoder is a combinational circuit element that encodes a set of binary codes into another set of binary codes containing a smaller number of bits. The multiplexer is a combinational circuit element that channels one of its many inputs to its only output depending on the selection inputs.

What are the functions of multiplexer inputs?

A multiplexer performs the function of selecting the input on any one of 'n' input lines and feeding this input to one output line. Multiplexers are used as one method of reducing the number of integrated circuit packages required by a particular circuit design. This in turn reduces the cost of the system.

What is the role of multiplexer and decoder?

The main function of multiplexer basically is to connect information from one point to another point through wires while on the other hand, decoders converts the outputs for several operations such as data collection and calculations.

What is Computer multiplexer?

A multiplexer is a device that takes multiple analog signals and forwards the selected input into a single line. These devices are used to increase the amount of data that can be transmitted over a network. A network multiplexer is used with a variety of signal types like digital, video, analog, and optical....

What is multiplexer and types?

There are mainly two types of multiplexers, namely analog and digital. They are further divided into FDM, WDM, and TDM.

What is multiplexer and demultiplexer in digital electronics?

Multiplexer processes the digital information from various sources into a single source. Demultiplexer receives digital information from a single source and converts it into several sources. It is known as Data Selector. It is known as Data Distributor. Multiplexer is a digital switch.

Why Enable is used in multiplexer?

It's often desirable to add an enable (or strobe) input EN to a multiplexer. An enable input makes the multiplexer operate. When EN = 0, the output is High-Z or less commonly LOW (depending on the specific device). When EN = 1, the multiplexer performs its operation depending on the selection line.

What is inside a multiplexer?

Normally, a multiplexer has an even number of 2ⁿ data input lines and a number of “control” inputs that correspond with the number of data inputs. Note that multiplexers are different in operation to Encoders.

What is the role of multiplexer when enable input is high?

multiplexers usually have an ENABLE input that can be used to control the multiplexing function. When this input is enabled, that is, when it is in logic '1' or logic '0' state, depending upon whether the ENABLE input is active HIGH or active LOW respectively, the output is enabled. The multiplexer functions normally.

Can a multiplexer work as a encoder?

10. Can an encoder be called a multiplexer? Explanation: A multiplexer or MUX is a combination circuit that contains more than one input line, one output line and more than one selection line. Whereas, an encoder is also considered a type of multiplexer but without a single output line and without any selection lines.

What is latch circuit?

In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs.
