What is embedded system

The embedded system is combination of hardware and software and it can be program to perform a specific task.

The embedded system are electronics system that contain a microprocessor or microcontroller.

An embedded system is a low cost high performance system.

Introduction of 8051 microcontroller

In 1981 , Intel corporation introduced an 8-bit microcontroller, called the 8051.

It has 8-bit data bus and 16-bit address bus.

This is an 8-bit microcontroller, means it can work on only 8-bit of data at a time.

Interrupts in 8051

An interrupt is the occurrence of an event that cause a temporary suspension of a program while the event is serviced by another program (Interrupt Service Routine ISR or Interrupt Handler).

There are two types of interrupt sources: 1. INTR0 2. INTR1

Counter & Timer in the 8051

The 8051 has 2 timers/counters: timer/counter 0 and timer/counter 1.

The timer is used as a time delay generator.

An event counter external input from input pin to count the number of events on registers.
