The training was quite useful for the participants. ARM Hardware and underlying concepts were thoroughly explained. The course was appreciated by all participants, however the last part, poring of OS on the Board, which most of the participants were keenly interested in, was covered in hurry, due to time limitation. Overall it was good experience and learning for the participants.

Embedded Systems

Frequently Asked Questions regarding Embedded Systems are as per below.

What is Embedded Systems?

Embedded systems, as the name suggests are smart device technologies built into larger devices. The embedded device is not a computer but can perform the assigned task of computing or data manipulation etc. If we look into TVs, Washing machines or even heating ovens, we find some piece of embedded systems at someplace

What makes an Embedded Systems different from a regular PC?

Even though the ES is capable of computation and other jobs done by PC, it is not a complete PC. It may not have a key board, a monitor or even for that matter a processor. The hardware and the OS of the Embedded systems might not be complete, but only the basic functionalities of OS are taken in a real time environment

What components constitutes an Embedded Systems?

The various components of an Embedded system are as per the following

Hardware

Real time Operating system (RTOS)

Processor

Various ports including Serial port, n/w port, i/o peripheral port

Sensors and actuators

Mechanical parts

What components constitutes an Embedded Systems?

Applications using ES must be reliable, safe and secureHigh efficiency

High efficiency

Mostly fixed set of application systems

Must react after guaranteed time limit

Most of the functionalities of the ES are implemented in software

What does the software in Embedded System do?

Respond to external events

Cope with unusual conditions without human interference

Carry out multiple jobs at a time

Replace some of the hardware components

What are the languages used for building the software in ES?

Usually C/C++ are preferred

Other languages such as Embedded C++ (EC++), Embedded java etc. are also being used

What are the common micro processors used for ES?

Zilog Z8 family

Intel 8051

X86 family

X86 family Motorola 68k family

Power PC family

What is RTOS?

RTOS stands for Real Time Operating System. It is a compact OS with all the essential features of PC operating system. It is the most suited Operating system for Embedded systems. It is the scale down version of the real time OS

What are the debuggers used in testing Embedded systems?

Many tools are used for debugging and testing embedded systems. A few of them are

Remote debugger: for monitoring and debugging the state of the embedded system software

In Circuit Simulator: for monitoring and controlling the state of the processor in the embedded systems

Simulators: used before the design of the Embedded systems and are used to simulate the functioning of the ES on the host machine

Logic analyzer: used to check the logical level of the various components of the ES

Oscilloscopes: to checking the analog signal and also for hardware debugging
