There are various conditions of Parallelism which are as follows −Data and resource dependencies − A program is made up of several parts, so the ability to implement various program segments in parallel is needed that each segment should be autonomous regarding the other segment. Dependencies in various segments of ... Read More

In many years, computer architecture has gone through evolutional instead of revolution changes supporting features are those that were demonstrated execution delivers.According to the figure we initiated with the Von Neumann architecture developed as a sequential machine implementing scalar information. Sequential devices enhanced from bit serial to word-parallel operations & ... Read More

It is widely observed that certain computer architecture classes and programming language classes correspond to one another. For example von Neumann architectures and imperative languages, or reduction architectures and functional languages. The corresponding architecture and language classes must have a common foundation or paradigm called a computational model.The computational model ... Read More

There are various elements of modern computers which are as follows −Computing Problems − It has been long identified that the theory of computer architecture is no greater limited to the mechanism of the bare machine hardware. A modern computer is an integrated system including machine hardware, an instruction set, ... Read More

There are few basic guidelines or design elements that distribute to categorize and differentiate buses.Bus TypesBus lines can be reported into two generic types are dedicated and multiplexed. A dedicated bus line is permanently authorized either to one function or a physical subgroup of computer components. A multiplexed bus line ... Read More

The hardware components of a computer are classified into five groups are Input unit, Central processing unit, Output Unit, Control Unit, Arithmetic & logical unit.Input unitInput units are used by the computer to read the information. The most frequently used input devices are keyboards, mouse, joysticks, trackballs, microphones, and so ... Read More

BCD adder refers to a 4-bit binary adder that can add two 4-bit words of BCD format. The output of the addition is a BCD-format 4-bit output word. It can descript the decimal sum of the addend and augend and a carry that is created in case this sum exceeds ... Read More

Decimal arithmetic operations refer to a digital function that does decimal micro-operations. This function adds or subtracts decimal numbers by forming 9’s or 10’s complement of the subtrahend. This decimal arithmetic unit first accepts coded decimal numbers and then generates output in the binary form.Algorithms that are used for arithmetic ... Read More

A subtractor circuit is required to perform a subtraction operation on two decimal numbers. BCD subtraction is slightly different from BCD addition. Performing subtraction operation by taking the 9’s or 10’s complement of the subtrahend and adding it to the minuend is economical.It is not possible to obtain the 9’s ... Read More

BCD adder refers to a 4-bit binary adder that can add two 4-bit words of BCD format. The output of the addition is a BCD-format 4-bit output word, which defines the decimal sum of the addend and augend and a carry that is created in case this sum exceeds a ... Read More
