Introduction to the digital systems technology and the embedded systems
Digital systems technology:
Can you live now without using digital systems? Like you do not have phone, intercom system, TV and other media technologies, what would be your life? Basically, every person needs digital help from home management to office management. In this era, no person is here who is surviving without using digital systems. Both hardware and software unite with each other to generate helpful digital systems. The world has become advanced, modern and technologized. There are a lot of examples of digital systems that have changed the lives round the world. These all digital supplies like lighting control, home theater, projectors, security cameras, intercom systems, television displays, digital signage and everything that is related to technology are digital systems. Even, your iPad, iPhone and tablet are digital systems that work according to embedded programs. A smartphone has various software, input components, applications, processor etc. that help in communication management, gaming, security, media management, networking etc. You can easily install such items at your home. Technology has become a part of lives in different situations. A human is dependent on technology.
Saving your from thieves to connecting your around the world via video conferencing are perfectly examples of the advantages of digital systems. Digital systems provide helpful solutions that have the ability to simplify media technologies. These systems have the ability to provide you security from sending an SMS if an intruder comes to your home or giving you an alert through alarm etc. From security to home to commercial purposes, digital systems cover all. You can even install digital system at your home to guard your children if you are a working person. Hence, digital systems technology has completely changed the perspectives, approaches, living styles and simply lives.
Embedded systems:
You can simply say embedded system a controller. Basically, embedded systems are controllers. This controller works with a dedicated function within a big electrical or mechanical system. This controller often performs with real-time calculating constraints. Embedded systems are the controllers of digital systems or simply devices. Almost 98% of all the microprocessors in the market are used in these embedded systems. Now, you can take idea of how important the embedded systems are. No digital system is complete without embedded system. In this era, advanced embedded systems are generally based on microcontrollers, for instance, microprocessors along with incorporated memory and peripheral edges. But it should be noted that ordinary microprocessors are also useful in the market. Ordinary processors use peripheral interface and external chips for memory. Ordinary processors are common for complex systems. You will find them getting used in wide range in the market.
In any case, processors are useful. They can be used from general purposes to commercial or industrial purposes for complicated computations. They can be even designed for certain applications. DSP means digital signal processor works as a common class for dedicated processors. Actually, the embedded systems are always used for performing special tasks. Design engineers know better and they manage the cost and size of the final product. They also enhance the performance and reliability of the product due to their years of experience and skills. There are some embedded systems that are behind the welfare of a country’s economy. Let’s take a look at some of the examples of embedded systems that range from portable devices like MP3 players, digital watches, programmable logic controllers, hybrid vehicles, traffic light controllers, avionics, medical imaging systems and so on. There are low to high and small to large level embedded systems available in the market.
