…..By Pine Academy

INTRODUCTION OF THE COMPANY

PINE Training Academy is a training division of Techadityaa

(www.techadityaa.com)

Pine Training Academy was established in 2014 by technocrats having

expertise and vast work experience in the field of ASIC Design, FPGA, and

DSP, ASIC Verification, real-time embedded system design and board PCB.

We understand the dynamics and requirements of the industry. While working

in the industry we realized that there is a vast gap between the job profile

required for the particular job and the kind of candidates available in the

market.

To bridge this gap we decided to start this academy to train the candidates as

per the market requirements.

WHAT IS EMBEDDED SYSTEM?

Embedded systems are devices used to control, monitor or assist the operation of

equipment, machinery or plant. “Embedded” reflects the fact that they are an

integral part of the system.

An embedded system is some combination of computer hardware and software,

either fixed in capability or programmable, that is specifically designed for a

particular function.

BASED ON PERFORMANCE AND FUNCTIONAL REQUIREMENT

Real-time embedded systems are defined as those systems in which the correctness of

the system depends not only on the logical result of computation, but also on the time

at which the results are produced.

Hard real-time systems (e.g., Avionic control).

Firm real-time systems (e.g., Banking).

Soft real-time systems (e.g., Video on demand).

1.REAL TIME EMBEDDED SYSTEM

2.STAND ALONE EMBEDDED SYSTEM

A standalone device is able to function independently of other hardware. This means

it is not integrated into another device.

It takes the input from the input ports either analog or digital and processes,

calculates and converts the data and gives the resulting data through the connected

device-Which either controls, drives and displays the connected devices.

For example, a TiVo box that can record television programs , mp3 players are

standalone devices

3.NETWORKED EMBEDDED SYSTEM

These types of embedded systems are related to a network to access the resources.

The connected network can be LAN, WAN or the internet. The connection can be

any wired or wireless. This type of embedded system is the fastest growing area in

embedded system applications. .

Mobile embedded systems are used in portable embedded devices like cell

phones, mobiles, digital cameras, mp3 players and personal digital

assistants, etc.

The basic limitation of these devices is the other resources and limitation of

memory.

4.MOBILE EMBEDDED SYSTEMS

Based on the Performance of the Microcontroller

Small Scale Embedded Systems

These types of embedded systems are designed with a single 8 or 16-

bit microcontroller, that may even be activated by a battery.

For developing embedded software for small scale embedded systems, the main

programming tools are an editor, assembler, cross assembler and integrated

development environment (IDE).

Medium Scale Embedded Systems

These types of embedded systems design with a single or 16 or 32 bit

microcontroller, RISCs or DSPs.

These types of embedded systems have both hardware and software complexities.

For developing embedded software for medium scale embedded systems, the

main programming tools are C, C++, JAVA, Visual C++, RTOS, debugger,

source code engineering tool, simulator and IDE.

Sophisticated Embedded Systems

These types of embedded systems have enormous hardware and software

complexities, that may need ASIPs, IPs, PLAs, scalable or configurable

processors.

They are used for cutting-edge applications that need hardware and software

Co-design and components which have to assemble in the final system.

Industrial machines, automobiles, medical equipment, cameras, household

appliances, airplanes, vending machines and toys (as well as the more obvious

cellular phone and PDA) are among the myriad possible hosts of an embedded

system.

HOW DO WE IMPLEMENT THEM?

We do so by using microcontrollers (or microprocessor based systems)

Or simply by using digital circuits that perform the function we want.

Digital circuits Microprocessor based systems

Faster

Only propagation delay

Slower

Technology Dependent

Inflexible

Functions they perform can’t be changed

easily.

Flexible

We need only to update the software.

Example:

Communication system

Ciphering algorithm

Example:

Personal computer,PDA’s

Mobile phones,PLC’s
