A bus transfer is the most effective method to send data by using a common bus system. It is constructed using common bus registers in multiple registers. The mechanism of the bus includes a collection of lines. These lines are registers of one bit each, which share only one information at a time. The data transfer is contained by the control signals.The two methods that can be used in Bus transfer are as follows −Using multiplexerUsing three states bus buffersUsing MultiplexerA common bus can be generated using a multiplexer. It facilitates in choosing the source register to place the binary ... Read More

Registers define the storage area that influences the data and instructions. It can send data and instructions from one register to another register, memory to register, and memory to memory, the register transfer approach is used. This register is used in the transmission of data and instructions between memory and processors to implement the particular tasks.The data transfer from one register to another is named in representative design using a replacement operator. The statement isR2←R1It indicates a transfer of the content of register R1 into register R2. It labelled a replacement of the content of R2 by the content of ... Read More

The floating-point representation can implement operations for high range values. The numerical evaluations are carried out using floating-point values. It can create calculations easy, scientific numbers are described as follows −The number 5, 600, 000 can be described as 0.56 * 107.Therefore, 0.56 is the mantissa and 7 is the value of the exponent.Binary numbers can also be described in exponential form. The description of binary numbers in the exponential form is called floating-point representation. The floating-point representation breaks the number into two parts, the left-hand side is a signed, fixed-point number known as a mantissa and the right-hand side ... Read More

Fixed-point is an elementary and simple method to define factorial numbers. The fixed-point numbers help a constant amount of bits. The “fixed-point” defines the decimal point of a number. There is no free symbol to name where the decimal point promote. But, in binary, bits can either be 0 or 1.Decimal Fixed-Point RepresentationFixed-point representation has a radix point known as decimal point. Fixed-point numbers having decimal points at the right end of the number are treated as integers because the fixed-point numbers having decimal points at the left end of the number are treated as fractions. In this method, the ... Read More

Complements are used in digital computers for facilitating the subtraction operation and for logical manipulation. There are two methods of complements for each base r system: the r's complement and the (r - 1)'s complement.(r - 1)'s Complement9's complementGiven a number N in base r having n digits, the (rn - 1)'s complement of N is represented as (rn- 1) - N. For decimal numbers r = 10 and r - 1 = 9, therefore the 9's complement of N is (10n - 1) - N.Now, 10n defines a number that includes a single 1 followed by n 0's. 10n ... Read More

A digital circuit that executes the inverse services of a decoder is known as an encoder. It has 2ninput lines and n output lines. In an encoder, the output lines create the binary code equivalent to the input value. The diagram shows the general architecture of an encoder circuit.Decimal to BCD EncoderThe decimal to BCD encoder has ten input lines and four output lines. The input for the encoder is the decoded decimal data and encoded BCD is the output accessible on the four output lines. The diagram demonstrates the logic symbol for decimal to BCD encoder IC.The diagram demonstrates ... Read More

A binary decoder is a decoder that has an n-bit binary input code and one activated output which is chosen from output codes. This decoder is accessible in instances where it is important to simulate directly one of the outputs based on an n-bit input value. In a 2 to 4 decoder, 2 inputs are decoded into four outputs, each output describing one of the min-terms of the 2 input variables. The two inverters support the complement of the inputs and each one of the four AND gates creates one of the min-terms.The diagram shows the circuit diagram of a ... Read More

A circuit that makes data on an individual line and sends the data on any of the 2 n possible output lines is known as a demultiplexer. Hence, a demultiplexer is known as a single-input multiple-output switch. The values of n selection lines control the selection of a determined output line.A demultiplexer is demonstrated in the diagram.The truth table of a demultiplexer circuit is demonstrated in the table.EnableS1S0DinY0Y1Y2Y30XXX0000100000001001100010100001011010011110000110100101110000011110001A demultiplexer is used extensively in clock demultiplexer, security monitoring system, synchronous data transmission system, etc.Application of DeMultiplexerDemultiplexer can link a single source to various destinations.

A multiplexer is a combinational circuit that obtains binary data from one of 2" input data lines and manages it to an individual output line. The selection of a specific input data line for the output is decided by a collection of selection inputs. A 2"-to-1 multiplexer has 2" input data lines and n input selection lines whose bit combinations decide which input data are chosen for the output.A 4-to-1-line multiplexer is demonstrated in the figure. Each of the four data inputs I0 through I3 is used to one input of an AND gate. The two selection inputs S1 and ... Read More

A register that goes through a fixed series of states upon the software of input pulses is known as a counter. The input pulses can be clock pulses or can emerge from an outside source. They can appear at orderly intervals of time or at random.Counters are initiate in almost all apparatus including digital logic. It can be used for counting the multiple occurrences of an event and are beneficial for producing timing signals to regulate the sequence of operations in digital computers. There are multiple sequences that a counter can follow and the consecutive binary sequence is clean and ... Read More
