Implementation of Micro Instructions Sequencer
An Overview Digital processor processes can be flexibly managed by microprogrammed control units. The micro instruction sequencer, a vital component responsible for retrieving and carrying out micro instructions, is at the Centre of a microprogrammed control unit. In this article, we will examine the design of a micro instruction sequencer and see how it is put into practice. Micro Instructions Sequencer A circuit that manages the sequencing of microinstructions in a computer with microprogramming is known as a micro-instruction sequencer. It is in charge of creating the addresses for the subsequent micro-instruction to be executed and making sure that they ...
Read MoreImplementation of Digital System
An Overview Our modern world is now completely dependent on digital technology, which also drive innovation and change entire industries. Advanced functionality, effective processing, and seamless connectivity are made possible by digital systems, which are used in everything from computers to cellphones to communication networks to control systems. This article will examine the design and execution of digital systems, illuminating the crucial processes necessary to fully utilize digital technology. Digital System Systems that process and transmit data using binary representation are referred to as digital systems since they run on digital signals. These systems rely on discrete values of 0s ...
Read MoreImplementation of Decoder using VHDL
An Overview Decoders are used by digital systems to transform encoded data into a more intelligible format. In many different applications, including memory addressing, data routing, and control systems, these essential components are frequently used. The implementation of a decoder using VHDL (Very High-Speed Integrated Circuit Hardware Description Language) will be discussed in this article. Before physical implementation, designers can model and simulate digital circuits using the potent hardware description language known as VHDL. We'll approach comprehending and putting a decoder into use using VHDL step-by-step. Decoder A decoder is a combinational logic circuit that uses a particular decoding strategy ...

Read MoreTypes of Integrated Circuits (ICs)
In this article, we will discuss different types of ICs (Integrated Circuits) in electronics. As we know, the integrated circuits (ICs) are one of the crucial parts of all electronic devices and systems. Without ICs, most of the hi tech electronic devices and gadgets that we use would cease to exist. Integrated circuits made the electronic devices and systems so small that they became an integral part of every field of human life. Therefore, integrated circuits or ICs are entirely responsible for miniaturization of electronic devices and circuits. Before discussing different types of ICs, let us first understand a ...
Read MoreRealization of a logic function in SOP form using NAND gate
SOP Form SOP form stands for Sum of Products form. SOP form is one in which a Boolean expression is expressed as a sum of product terms. For example, $$\mathrm{\mathit{f}\lgroup A, B, C\rgroup=AB+ABC+B\overline{C}}$$ This is a Boolean function expressed in SOP (Sum of Products) form. NAND Gate The NAND Gate is a type of universal logic gate. It is a logic gate one that can be used to realize any kind of logical function or any other type of logic gate. A NAND gate is basically a combination of two basic logic gates namely AND gate and NOT gate, i.e. ...
Read MoreRadix Conversion in Digital Electronics
In positional number systems, the radix is the total number of unique digits that are used to represent numbers in that number system. Radix is also called Base. For example, in decimal number system, we use total ten digits from 0 to 9 (i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) to represent any decimal number. Therefore, for the decimal number system, the radix or base is ten (10). Although we can easily convert a given number from one radix (i.e. number system) to any other radix (number system) by using radix conversion protocols. In this article, ...
Read MoreElectronic Logic Conventions
Electronic logic conventions are the sets of rules followed while designing a digital logic system or device. These conventions are adopted due to their different characteristics observed by several experiments. The use of electronic logic conventions, makes the implementation process of a digit system easy and smooth. Also, a standardization is achieved in the design. This tutorial is entirely meant for explaining different electronic logic conventions used in digital system implementations. As we know, the digital systems are implemented in binary number system due to some technical and economic reasons. The binary number system follows Boolean’s rules to perform arithmetic ...
Read MoreConverting SSOP to SPOS Form
A Boolean function can be expressed into two forms namely, Sum of Products (SOP) Form Product of Sums (SOP) Form The SOP (Sum of Products) form is one in which the Boolean function is expressed as the sum of product terms, while in the POS (Product of Sums) form, the Boolean function is expressed as the product of sum terms of the function. But, in the SOP and POS form, each term of the function may not contain all the variables. For example, consider a Boolean function in three variables, $$\mathrm{\mathit{f}\lgroup A, B, C\rgroup=A\overline{B}+\overline{B}C}$$ This is the ...
Read MoreConversion between Canonical Forms
When a logical expression or Boolean function is expressed as a sum of minterms or as a product of maxterms, then it is called the canonical form of the expression or function. A canonical form of the Boolean expression is also known as standards form, i.e. Standard Sum of Products (SSOP) Form and Standard Product of Sums (SPOS) Form. The canonical form of a Boolean function involves minterms and maxterms. A minterm is a product term which contains all the variables of the Boolean function either in complemented or un-complemented form. A maxterm is a sum term which ...
