Machine-Independent Optimizations in Compiler Design

Machine-Independent Optimizations The main aim of machine-independent optimization is to improve the generated intermediate code so that compiler can get better target code. Eliminating unwanted code from the object code or replacing one set of code with another set...

Intermediate-Code Generator Compiler Design

Intermediate-Code Generator The process of translating a source language into machine code for a given target machine is done by intermediate-code. It lies between the high-level language and the machine language. See the below image that illustrates the position of...

Data Flow Analysis in Compiler Design

Data Flow Analysis All the optimization techniques we have learned earlier depend on data flow analysis. DFA is a technique used to know about how the data is flowing in any control-flow graph. Example: Forglobal common sub-expression elimination, we need to find the...

Basic Blocks and Flow Graphs in Compiler Design

Basic Blocks and Flow Graphs In this section, we are going to learn how to work with basic block and flow graphs in compiler design. Basic Block The basic block is a set of statements. The basic blocks do not have any in and out branches except entry and exit. It...

Switch Case Statement Compiler Design

Case Statement The “case” or “switch” statement is available in various languages. The following is the syntax for the case statement: switch (E)  {             case V1: S1             case V2: S2                    ....             case Vn-1: Sn-1    ...

Optimization of Basic Blocks in Compiler Design

Optimization of Basic Blocks We can apply the optimization process on a basic block. While optimization, there is no need to change the set of expressions computed by the block. The basic block optimization can be done in two ways: Structure-Preserving...

Boolean Expression in Compiler Design

Boolean Expression The translation of conditional statements such as if-else statements and while-do statements is associated with Boolean expression’s translation. The main use of the Boolean expression is the following: Boolean expressions are used as...

Translation of Array References in Compiler Design

Translation of Array References We can access the elements of an array stored in consecutive blocks very easily and quickly. In a programming language like C and Java, the size of an array is one less than the number of the element stored in an array. We can...

Micro-Operations

Micro-Operations If CPU wants to perform any operation, suppose execution of only one instruction or even break it down one particular execution phase (like fetch instruction, write back, decode, operand fetch etc.). CPU cannot perform one operation in one single...

Data Path, ALU and Control Unit

Data Path, ALU(Arithmetic Logic Unit) and Control Unit What is the Data path? Suppose any data processing operation should be performed in the CPU like transferring the content of register from one place to another, from one register to another register, performing...

Control Unit Organization

Control Unit Organization The Control Unit is the unit in the CPU, which controls the various components like input  & output devices, logic unit and memory. The Control Unit is the circuitry that controls or directs the component’s operations and tells them...

PL/SQL Tutorial

PL/SQL Introduction PL/SQL, also known as “Procedural Language extensions to the Structured Query Language.” As you can guess from the name PL / SQL, it is an extension of SQL ( structured query language ). SQL is one of the most used database languages to update and...

AVL Tree

AVL Tree AVL Tree is referred to as self-balanced or height-balanced binary search tree where the difference between heights of its left subtree and right subtree (Balance Factor) can’t more than one for all nodes covered by a tree. Example: We can say a tree is...

Circular Queue

Circular Queue Circular Queue is special type queue, which follows First in First Out (FIFO) rule and as well as instead of ending queue at the last position, it starts again from the first position after the last position and behaves like circular linear data...

Full Form of ATM

Full-Form of ATM In today’s techno-driven world, you can easily take cash out from your nearby ATM. But many of you still do not know what does ATM stands for? An ATM stands for Automatic Teller Machine. This tutorial will briefly learn about the definition, types,...

Full Form of GDP

Full Form of GDP We often came across the word GDP in debates, news, talk shows, and various other economic factors. Economists mostly refer to this word while speaking about the size of the economy. GDP is an essential estimate of the overall health of our economy....

Full Form of CAB

Full Form of CAB CAB was one of the most controversial topics of 2020, which triggered violent protests, riots, and rallies across the entire nation, majorly in the north-east, West Bengal and New Delhi. But do you know what the full form of CAB is? The full form of...

Pipeline run details view – Jenkins

Pipeline run details view: Blue Ocean’s pipeline run details view section displays all the details about a single pipeline run. This section also allows you to make a modification in that run or restart that run. Here are some features (options) and details of...

Activity View in Blue Ocean – Jenkins

Activity View in Blue Ocean: Blue Ocean’s activity view displays all the activity of a single pipeline process on the screen. Activity view has a navigation bar on the screen, which contains all the options related to the pipeline process. Navigation bar:...

Blue Ocean’s Dashboard – Jenkins

Blue Ocean’s Dashboard: Whenever you open the Blue Ocean, the default view (screen) that comes out is known as the Blue Ocean’s Dashboard. The Blue Ocean’s dashboard shows the pipeline project’s overview, which is currently running on the...
