 What is ChatGPT ? ChatGPT  is an AI (Artificial Intelligence) chatbot , which is developed by OpenAI.  It takes text as input and responds to it like a human. It was launched in NOVEMBER 2022. In ChatGPT ,GPT stands for Generative Pre-trained Transformer. It is among the latest sensations in the field of AI. How to access ChatGPT ? To use ChatGPT the first step is to sign up on OpenAI and create an account on it. Here is the link " https://openai.com/blog/chatgpt/ ". By clicking the above link the interface looks like, Now, click on the "TRY CHATGPT" and signup/login using your credentials. Is ChatGPT free to use ? Free ChatGPT service is not available anywhere,but ChatGPT will only be available to U.S customers for now. On February 2023 OpenAI has announced that it was introducing "ChatGPT Plus"  by launching a pilot subscription plan for ChatGPT. The new subscription plan, ChatGPT Plus, will be available for $20/month, and subscribers will receive a num...

  Difference between a microprocessor and a microcontroller Microprocessor A silicon chip representing a central processing unit (CPU), which is capable of performing arithmetic as well as logical operations according to a predefined set of instructions. It is a dependent unit. It requires the combination of other chips like timers, program and data memory chips, interrupt controllers, etc. for functioning. Most of the time general purpose in design and operation. Doesn't contain a built in I/O port. The I/O port functionality needs to be implemented with the help of external programmable peripheral interface chips like 8255. Targeted for high end market where performance is important. Limited power saving options compared to microcontrollers. Microcontroller A microcontroller is a highly integrated chip that contains a CPU, scratchpad RAM, special and general purpose register arrays, on chip ROM/FLASH memory for program storage, timer and interrupt control units and dedicated I/O ...

  CLASSIFICATION OF EMBEDDED SYSTEMS Some of the criteria used in the classification of embedded systems are as follows: (1) Based on generation (2) Complexity and performance requirements (3) Based on deterministic behavior (4) Based on triggering Classification Based on Generation First Generation :  The early embedded systems were built around 8bit microprocessors like 8085 and Z80, and 4bit microcontrollers. Simple in hardware circuits with firmware developed in Assembly code. Digital telephone keypads, stepper motor control units etc. are examples of this. Second Generation   :  These are embedded systems built around 16bit microprocessors and 8 or 16 bit microcontrollers, following the first generation embedded systems. The instruction set for the second generation processors/controllers were much more complex and powerful than the first generation processors/controllers. Some of the second generation embedded systems contained embedded operating...

  Major Application Areas of Embedded Systems We are living in a world where embedded systems play a vital role in our day-to-day life, starting from home to the computer industry, where most of the people find their job for a livelihood. Embedded technology has acquired a new dimension from its first generation model, the Apollo guidance computer, to the latest radio navigation system combined with in-car entertainment technology and the wearable computing devices (Apple watch, Microsoft Band, Fitbit fitness trackers etc.). The application areas and the products in the embedded domain are countless. A few of the important domains and products are listed below: (1) Consumer electronics: Camcorders, cameras, etc. (2) Household appliances: Television, DVD players, washing machine, fridge, microwave oven, etc.  (3) Home automation and security systems: Air conditioners, sprinklers, intruder detection alarms, close! circuit television cameras, fire alarms, etc. (4) Automotive indu...

  Introduction to Embedded Systems WHAT IS AN EMBEDDED SYSTEM? An embedded system is an electronic/electro-mechanical system designed to perform a specific function and is a combination of both hardware and firmware(software). Difference between embedded and general purpose computing system Embedded System A system which is a combination of special purpose hardware and embedded OS for executing a specific set of applications. May or may not contain an operating system for functioning. The firmware of the embedded system is pre-programmed and it is non alterable by the end-user (There may be exceptions for systems supporting OS kernel image flashing through special hardware settings). Application-specific requirements (like performance, power requirements, memory usage, etc.) are the key deciding factors. Highly tailored to take advantage of the power saving modes supported by the hardware and the operating system. For certain category of embedded systems like mission critical syste...
