Overview of Embedded systems and Embedded systems programming

Embedded Systems
In embedded system, an embedded product uses a microprocessor or microcontroller to do one task only. In an embedded system, there is only one application software that is typically burned into ROM

Areas under Embedded systems

Assembly line quality monitors, Bar code readers, Bread machines, Cameras, Mobile phones, Car assembly machines, CD players, drive controllers, music systems, smart Telephones, pump controllers, Welding machines, Windmills, Wrist watches.

Embedded systems programming

Embedded systems programming caters to optimum utilization of: Time, Space, Communication channels, Files, ROM (Read-Only Memory), Flash memory. (Real Time Operating System) sometimes involving device driver architectures

What is embedded c

Embedded C is a subset of C language which is compatible with certain microcontrollers.

What is Microcontroller?

Microcontroller combines many components of a microprocessor into a single chip. So a microcontroller combines onto the same microchip: The CPU core, Memory (ROM and RAM, parallel digital I/O

Example Motorola’s 6811, Zilog’s Z8 and PIC 16X, Intel’s 8051, , ATMEL 89S51,52 etc…

Microcontroller training plays very important role in having hands-on exposure to microcontroller

What is a 8-bit microcontroller?

8-bit means it can process 8-bit data per clock cycle. It has 8-bit data bus and can process 1byte(i.e. 8 bit) of data at a time. It was developed by Atmel Corporation. AVR Microcontroller implies it belongs to AVR family. ‘8’ in Atmega8 means this microcontroller has 8Kb of flash memory

What is AVR Microcontroller


Ø AVR is a fast 8-bit RISC chip microcontroller from Atmel Corporation

Ø AVR Microcontroller executes most of the instructions in single execution cycle

Ø They are less power consuming and can be operated different power saving modes

AVR Microcontrollers are mostly used component in electronics today. Engineers undergone AVR Microcontroller training have edge over others in getting entry in core companies.

Microprocessor v/s Micro-controllers

Microprocessors are High power dissipation devices with high cost. They need peripheral devices to work , mostly used in microcomputers.

Microcontroller is a very important component in modern electronic systems. Its use is so widespread that it is almost impossible to work in electronics without it. Microcontrollers are used in a wide number of electronic systems such as: Security alarm systems, fire alarm systems, and building automation systems, Special-purpose Applications, Keyboard of a PC, Electronic measurement instruments, such as digital multi-meters, frequency etc.
