What is Floating-Point Representation in Computer Architecture?
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 MoreWhat is Fixed Point Representation in Computer Architecture?
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 MoreWhat is the purpose of Complements in Computer Architecture?
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 MoreWhat is Binary Decoder?
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 MoreWhat are Binary Counters?
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 MoreWhat is Shift Register?
A register adequate for changing its binary data in one or both directions is known as a shift register. The logical design of a shift register includes a series of flip-flops, with the output of one flip-flop linked to the input of the next flip-flop.Operations of Shift RegisterThere are various modes of operations of shift registers which are as follows −Serial-In Serial-Out Shift RegisterThe controlling of shifting of information decides the ‘serial-in serial-out’ shift register into the right shift and left shift register. The diagram demonstrates a ‘serial-in serial-out’ right shift register.During the first clock pulse, the signal on the ...
Read MoreWhat are Registers?
A register is a set of flip-flops with each flip-flop adequate for saving one bit of data. An n-bit register has a set of n flip-flops and is adequate for saving any binary data of n bits. In the flip-flops, a register can have combinational gates that implement specific data-processing operations.A register includes a set of flip-flops and gates that influence their change. The flip-flops manage the binary data and the gates control when and how current data is moved into the register.There are multiple kinds of registers that are accessible economically. The elementary register includes just flip-flops, with no ...
Read MoreExplain the performance of Addition and Subtraction with signed magnitude data in computer architecture?
A signed-magnitude method is used by computers to implement floating-point operations. Signed-2’s complement method is used by most computers for arithmetic operations executed on integers. In this approach, the leftmost bit in the number is used for signifying the sign; 0 indicates a positive integer, and 1 indicates a negative integer. The remaining bits in the number supported the magnitude of the number.Example: -2410 is defined as −10011000In this example, the leftmost bit 1 defines negative, and the magnitude is 24.The magnitude for both positive and negative values is the same, but they change only with their signs.The range of ...
Read MoreWhat are the functions of Scheduling Model in computer architecture?
A scheduling system consists of program tasks, a target machine, and a schedule in which a specific performance criterion is optimized.Program Tasks − The characteristics of a parallel program can be defined as the system (T,
Read MoreWhat is scheduling problem in computer architecture?
The general scheduling problem has been described in different ways in different fields. The classical problem of job sequencing in production management has influenced most of the solutions to this problem, which generally assumes a set of resources that could provide service to a set of consumers. The main objective is to find an efficient policy for managing the access to the resources by the consumers to optimize some desired performance measures.In distributed systems, the scheduling problem arises because the concurrent parts of a program or set of programs must be arranged in time and space so that the overall ...
