An embedded system is a computer system designed to do one or a few dedicated and/or specific functions often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today.
Physically, embedded systems range from portable devices such as digital watches and MP3 players, to large stationary installations like traffic lights, factory controllers, or the systems controlling nuclear power plants. Complexity varies from low, with a single microcontroller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or enclosure.
The 8284 clock generator IC provides clock signals and synchronization for the 8086/8088 microprocessors. It generates the CLK signal from either an internal crystal oscillator or external clock source. It also produces a divided PCLK signal and synchronizes the READY signal based on the RDY1 and RDY2 pins. The 8284 ensures proper reset timing for the 8086/8088 by holding the RESET signal low for at least 4 clock cycles after power on.
Overview of Crystal Oscillator Circuit Working and Its Applicationelprocus
The document discusses crystal oscillator circuits, which use a piezoelectric crystal to create an electrical signal at a precise frequency. It describes different types of oscillator circuits, how quartz crystals produce oscillations via the piezoelectric effect, and example crystal oscillator circuit diagrams. Applications are discussed, including in microprocessors to provide clock signals, and industrial uses like computers, telecommunications equipment, and sensors.
This presentation provides an overview of embedded systems and describes a collision avoidance robot project. It introduces embedded systems and gives examples. It then describes the key components of embedded systems like processors and memory. It discusses the software used for the project. It introduces the collision avoidance robot project, describing its sensors, control unit, actuators and working. It provides code snippets to show how the robot's movement is controlled based on sensor input to avoid collisions.
This document discusses the differences between saints and swindlers. It defines a saint as someone who serves God unconditionally without expectations of reward. Saints are described as living detached lives according to sacred texts, serving all people impartially and without ego. In contrast, swindlers use deception to deprive others of money and possessions by distorting spiritual teachings for personal gain. They pretend to have saintly qualities like mystical powers but lack true virtues. The document advises that when seeking help, one should look for a genuine spiritual master who can guide them towards God, rather than swindlers who wish to be worshipped themselves. A real guru teaches devotion to God alone and how to serve God and all people.
This document defines embedded systems and describes their typical hardware components. It provides examples of embedded systems including PDAs, cell phones, automobiles, medical imaging devices, and more. The main hardware units of an embedded system are then outlined, including the power source, clock oscillator, timers and real-time clocks, reset circuit, memory, input/output ports and interfaces, analog-to-digital converters, input and output devices, and networking components. Interrupt handlers are also noted as an important hardware unit.
The document discusses various hardware units commonly found in embedded systems, including power supplies, oscillators, reset circuits, I/O ports, displays, memories, timers, and converters. It covers topics like power saving techniques, interrupt handling, programming languages, development tools, and sample applications for small, medium, and sophisticated embedded systems.
The document describes three types of embedded systems: small scale, medium scale, and sophisticated. Small scale systems use a single microcontroller with little hardware/software complexity. Medium scale systems can use multiple microcontrollers or DSPs with more complex hardware/software. Sophisticated systems have significant hardware/software complexity and may require specialized processors. The document also discusses different types of processors used in embedded systems like microprocessors, microcontrollers, DSPs, and application-specific processors.
This document provides an overview of microprocessor systems and embedded devices at different levels. It discusses that at the high end, Intel Pentium 4 processors operate at 3.2GHz and consume over 100W, while low-power embedded devices consume as little as 250-300mW. Computer technology is experiencing dramatic changes with processors doubling in speed every 1.5 years, and memory and storage capacities increasing exponentially. Future computers are predicted to have processors operating at 5GHz with 4GB of memory and 2TB of storage. Embedded systems face challenges in power consumption, size, cost, reliability and meeting application-specific requirements.
1. Embedded systems are computer systems designed to perform dedicated functions within larger mechanical or electrical systems, with software embedded in the hardware.
2. Hardware and software must be designed together in embedded systems. Key considerations include partitioning tasks between hardware and software, hardware design for low power and real-time needs, and software design for modularity, reusability, and real-time guarantees.
3. Real-time systems, including both soft and hard real-time systems, must guarantee response to external events within specified times to avoid glitches or catastrophic failures. The choice of hardware, software, and real-time operating system depends on these timing requirements.
The document discusses microprocessors and microcontrollers. It defines a microprocessor as the central processing unit (CPU) of a microcomputer that is contained on a single silicon chip. A microcontroller is similarly integrated but also includes memory and input/output ports, making it self-contained to control a specific system. The document provides details on the components and architecture of microprocessors, including registers, buses, memory, and I/O devices. It also summarizes the characteristics of the Intel 8085 microprocessor.
It is a presentation for the Embedded System Basics. It will be very useful for the engineering students who need to know the basics of Embedded System.
