INTRODUCTION OF EMBEDDED SYSTEM • A combination of software and hardware which is combined together to perform specific task. • An example of an embedded system is a microprocessor which controls an automobile engine. • An embedded system is designed to run on its own without human intervention, and may be required to respond to events in real time.
Microprocessors and Microcontrollers • The microprocessor is a processor on one • silicon chip. • The microcontrollers are used in embedded • computing. • The microcontroller is a microprocessor with • added circuitry.
APPLICATION OF EMBEDDED SYSTEM • Consumer Electronics : Camcorders, Cameras, etc… • Household Appliances : Television, DVD Player, Washing machine, fridge, microwave oven, etc. • Home automation and security system : Air conditioners, Sprinkler, intruder detection alarms, fire alarms, closed circuit television cameras, etc • Automotive industry : Anti-lock breaking system (ABS), engine control, ignition control, automatic navigation system, etc..
APPLICATION OF EMBEDDED SYSTEMS • Computer peripherals : Printers, scanners, fax machines, etc… • Computer Networking systems: Network routers, switches, hubs, firewalls, etc… • Health care : CT scanner, ECG , EEG , EMG ,MRI, Glucose monitor, blood pressure monitor, medical diagnostic device, etc. • Measurement & Instrumentation: Digital multi meters, digital CROs, logic analyzers PLC systems, etc… • Banking& Retail: Automatic Teller Machine (ATM) and Currency counters, smart vendor machine, cash register ,Share market, etc..
NEEDS OF AN EMBEDDED SYSTEM • Each Embedded system is designed to serve the purpose of any one or a combination of the following tasks. • 1. Data collection/Storage/Representation • 2. Data communication • 3. Data (Signal) processing • 4. Monitoring • 5. Control • 6. Application specific user interface
EMBEDDED DATA COMMUNICATION • Embedded data communication systems are developed in applications ranging from complex satellite communication systems to simple home networking systems.
EMBEDDED SYSTEM CONTROL • Embedded system with control functionalities impose control over some variables according to the input variables. • A system with control functionality contains both sensors and actuators. • Sensors are inputs ports for capturing the changes in environment variables or measuring variable. • Actuators are output ports are controlled according to the changes in input variable.
GENERAL PURPOSE PROCESSORS • Programmable device used in a variety of applications – Also known as ―microprocessor‖ • Features – Program memory – General datapath with large register file and general ALU • User benefits – Low time-to-market and NRE costs – High flexibility ―Pentium‖ the most well-known, but there are hundreds of others IR PC Register file General ALU Controller Datapath Program memory Assembly code for: total = 0 for i =1 to … Control logic and State register Data memory
EMBEDDED SYSTEM ESSENTIALS • INSTRUCTION SETS • CISC: Complex Instruction Set Computer • RISC: Reduced Instruction Set Computer • MEMORY TYPES • Volatile: Random Access Memory (RAM) • Non-volatile: Read Only Memory (ROM)
SUMMARY • An embedded system is a product that has one or more computers • embedded within it, which exercise primarily a control function. • The embedded computer is usually a microcontroller: a microprocessor • adapted for embedded control applications. • Microcontrollers are designed according to accepted electronic and • computer principles, and are fundamentally made up of microprocessor • core, memory and peripherals.
SUMMARY • Microchip offers a wide range of microcontrollers, divided into a number • of different families. Each family has identical central architecture and • instruction set. However, common features also appear across all their • microcontrollers. • The Microchip 12F508 is a good microcontroller to introduce a range of • features of microcontrollers in general and of PIC microcontrollers in • particular.
