A microcontroller (sometimes abbreviated µC‚ uC or MCU) is a small computer on a single integrated circuit containing a processor core‚ memory‚ and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip‚ as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications‚ in contrast to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are used in

ABSTRACT In the project design and development of footsteps based energy for street lights consists of pressure transducer‚ relay‚ comparator‚ battery‚ Real Time Clock(RTC)‚ micro controller‚ street light. The main aim of this project is to generate the energy through the pressure generated by footsteps.This micro controller setup is placed at foot path when a person walking along the foot path the footsteps of the person generates some pressure and that pressure generated by the person is noted

Computer Fundamentals Assignment What is a Computer? A computer is an electronic device that manipulates information‚ or "data." It has the ability to store‚ retrieve‚ and process data. You can use a computer to type documents‚ send email‚ and browse the internet. You can also use it to handle spreadsheets‚ accounting‚ database management‚ presentations‚ games‚ and many more. How does a computer work with? 1. Computer hardware equals the collection of physical elements that comprise

population. This enigma is‚ of course‚ the microprocessor. To an average observer a microprocessor is simply a small piece of black plastic that is found inside of almost everything. In How Microprocessors Work they are defined as a computer’s central processing unit‚ usually contained on a single integrated circuit (Wyant and Hammerstrom‚ 193). In plain English this simply means that a microprocessor is the brain of a computer and it is only on one chip. Winn L. Rosch compares them to being an electronic

programer. Computer architecture refers to those attributes of a system visible to a programmer or‚ put another way‚ those attributes that have a direct impact on the logical execution of a program. Computer organization refers to the operational units and their interconnections that realize the architectural specifications. 1.2. What‚ in general terms‚ is the distinction between computer structure and computer function? Structure is how devices are interrelated‚ while function is the individual

Chapter 5 Memory Organisation 5.1 Introduction The memory unit is an essential component in any digital computer since it is needed for storing programs and data. Main Memory The memory unit that communicates directly with the CPU is called the main memory. Auxiliary Memory Devices that provide backup storage are called auxiliary memory. The most common auxiliary memory devices used in computer systems are magnetic disks and tapes. The part of the computer system that supervises the flow of

TERM PAPER OF MICROPROCESSOR ON COMPUTER‚MICROCOMPUTER AND MICROPROCESSOR ABSTRACT Microprocessors have evolved dramatically in the twelve years of their development by the implementation of large numbers of devices on single chips. Word widths have increased along with microprogramming capabilities‚ addressing capabilities‚ and trends toward single-chip computers. Only a year after the introduction of 4-bit processors came the 8-bit processor. Three years later‚ in 1974‚ 16-bit processors
