The compiler is software that converts source code written in a high-level language into machine code. It works in two major phases - analysis and synthesis. The analysis phase performs lexical analysis, syntax analysis, and semantic analysis to generate an intermediate representation from the source code. The synthesis phase performs code optimization and code generation to create the target machine code from the intermediate representation. The compiler uses various components like a symbol table, parser, and code generator to perform this translation.Compiler design lecture 1 introduction computer science

How to Un-Obsolete Your Legacy Keypad DesignEpec Engineered Technologies
?
For any number of circumstances, obsolescence risk is ever present in the electronics industry. This is especially true for human-to-machine interface hardware, such as keypads, touchscreens, front panels, bezels, etc. This industry is known for its high mix and low-volume builds, critical design requirements, and high costs to requalify hardware. Because of these reasons, many programs will face end-of-life challenges both at the component level as well as at the supplier level.
Redesigns and qualifications can take months or even years, so proactively managing this risk is the best way to deter this. If an LED is obsolete or a switch vendor has gone out of business, there are options to proceed.
In this webinar, we cover options to redesign and reverse engineer legacy keypad and touchscreen designs.

Women’s security is a critical issue in today’s world and it’s very much needed for every individual
to be acting over such an issue. This document describes a GPS based “Women Security System''
that provides the combination of GPS devices as well as provide alerts and messages with an
emergency button trigger whenever somebody is in trouble They might not have so much time, all
that they have to do is generate a distress emergency signal by shaking up their phone. Our system
provides a realizable, cost effective solution to problem detection. Nowdays due to recently
happened cases such as rape by drivers or colleagues, burglary etc., women security, especially
women security has become the foremost priority of the world. System uses the Global Positioning
System (GPS) technology to find out the location of women. The information of women's position
provided by the device can be viewed on Google maps using Internet or specialized software. The
companies are looking for-ward to the security problem and require a system that will efficiently
evaluate the problem of women security working in night shifts, traveling alone. We focus on the
proposed model that can be used to deal with the security issue of women using GPS based tracking
systems.Microwatt: Open Tiny Core, Big Possibilities

A Cluster-Based Trusted Secure Multipath Routing Protocol for Mobile Ad Hoc N...IJCNCJournal
?
Mobile Ad Hoc Network (MANET) is a self-organizing and flexible system. MANET systems manage sensitive data from many distinct applications in various domains. Its dynamic nature increases its vulnerability to numerous types of security threats. Many of the present approaches using indirect approaches provide false approximations of trust degrees. It is significantly required a good routing system that meets Quality of Service (QoS) standards and enhances network performance. In this paper purposed cluster-based trustworthy safe multipath routing (CTSMP-Routing) for mobile ad hoc networks (MANETs). Load balancing challenge is addressed by using a modified proportional topology optimization (MPTO) approach using geographical data related to network nodes. The Enhanced Seeker Search Optimization (ESSO) approach is used to compute trust degrees after the clustering phase considering numerous network constraints including node mobility, received signal strength, energy consumption, and cooperation rate. Assumed to be the service node, the node showing the highest degree of trust manages inter-cluster routing. We have developed a hybrid soft computing approach termed the multi-layer deep recurrent neural network (ML-DRNN) to enhance the optimal path-finding process. This method selects, among many routes between source and destination nodes, the best one quickly. The outcomes of this paper demonstrate that CTSMP-Routing provides effective protection against several attack paths within the MANET environment and displays better performance in regard to quality of service (QoS) requirements.Proposal for folders structure division in projects.pdf

- 2. ? Computer programs are generally written in high-level languages (like C++, Python, and Java). A language processor, or language translator, is a computer program that convert source code from one programming language to another language or human readable language ? A compiler is a program that can read a program in one language i.e the source language and translate it into an equivalent program in another language which is the target language. A compiler
- 5. What Is an Interpreter? ? It is a program that functions for the translation of a programming language into a comprehensible one. ? It is a computer program used for converting high-level program statements into machine codes. It includes pre-compiled code, source code, and scripts. ? An interpreter translates only one statement at a time of the program. ? They create an exe of the programming language before the program runs.
- 7. ? Lexical Analysis: Lexical analysis or Lexical analyzer is the initial stage or phase of the compiler. This phase scans the source code and transforms the input program into a series of a token. ? A token is basically the arrangement of characters that defines a unit of information in the source code. NOTE: In computer science, a program that executes the process of lexical analysis is called a scanner, tokenizer, or lexer.
- 8. ?To read the input character in the source code and produce a token is the most important task of a lexical analyzer. ?The lexical analyzer goes through with the entire source code and identifies each token one by one. The scanner is responsible to produce tokens when it is requested by the parser. ?The lexical analyzer avoids the whitespace and comments while creating these tokens. If any error occurs, the analyzer correlates these errors with the source file and line number.
- 9. There are three terminologies- ? Token ? Pattern ? Lexeme Token: It is a sequence of characters that represents a unit of information in the source code. Pattern: The description used by the token is known as a pattern. Lexeme: A sequence of characters in the source code, as per the matching pattern of a token, is known as lexeme. It is also called the instance of a token.
- 10. The lexical analyzer performs the following tasks- ? The lexical analyzer is responsible for removing the white spaces and comments from the source program. ? It corresponds to the error messages with the source program. ? It helps to identify the tokens. ? The input characters are read by the lexical analyzer from the source code.
