- 1 Evolutionary Trends in Embedded System Design
Evolutionary Trends in Embedded System Design
In every day of our life, we will meet with a lot of embedded system devices. It can be either a cell phone, a smart card, a music player, a router or the electronics in the automotive _ all these devices touching and changing our lives like never before. If someone asks us to explain about embedded systems we can answer them like, it is a combination of computer hardware, software and other supporting technical components with all which is designed to perform a dedicated task.
Recent Trends in Embedded Systems:
The below given are the trends in embedded systems.
Multi-core Processors :
For quite a long time we are familiar and using widespread 8-bit controllers for powering a lot of embedded applications. Like in automotive, home appliances, etc. For the better or higher the performance we can upgrade to 16-bit controllers or 32-bit controllers to use in cell phone and media players.
By the evolution o the micro-controllers from 8bit to 32bit, there were no challenges or programming changes in the architecture of controllers. But it is a challenge when a transition to a multi-threaded architecture. So multi-core programming requires a change in embedded applications. Like, developers need to change systems architecture, design, debugging, testing to get the best from these systems.
In the embedded systems industry, embedded devices were operating as stand-alone systems. But by the invention of wireless connectivity, the scenario got changed. We are connecting the devices with wireless protocols to transmit and receive data. For this purpose we are using short-range protocols like Bluetooth, Zigbee, RFID, etc. and long-range protocols like Wireless Local Area Network(WLAN), WiMAX, long-term evolution(LTE)Etc.
SoC Architectures :
SoC architecture means a system on chip architecture. For the low-cost applications device, there are a lot of developments are happening in the architecture of wireless devices. For this good improvement are happening in this direction are the integration of microcontrollers with radio modem in 64 pin configuration microcontrollers. Similar devices are available in the respective market also.
Power Consumption :
Another main change researchers want in this field is to reduce the power consumption. For that, they are looking forward to making the device, which should remain in sleep mode when it is not doing anything. That means when the in the “sense and transmit” the sensing will be scheduled. So whenever the device wants to sense then only it becomes active. Rest of the time (for more than 99% of the time)it can go under sleep mode. This period current consumption will be 1-2microA.
Increased Use of Open Source Technology :
In older days, the embedded system was employed with hardware, software, communication protocols and their own built operating systems for their development. Because the payment for the license of operating systems is high.
But now the scenario is changing, we are able to get operating systems freely. Free in the sense of there are a lot of open sources operating systems are coming so we can use it for our product development. For example Embedded Linux. Embedded Linux licensed and a free version still remains a good choice for a lot of developers.
As the increase in the world of interconnected the security also became a problem for embedded devices. Now everything we are doing with the ease of internet only so all the required data we are sharing on the internet and related devices. The security requirements depend on memory, its middleware, and low computing power. Embedded security is the new important matter among embedded devices. The improvement in the field of embedded security will matter on embedded encryption, trusted computing, cryptology, authentication.
Smart Devices :
When we hear the “smart first thing ” we will remember smartphones. Nowadays we can do all our works on mobile. Machine to machine communication(m2m) has been used for the remote applications. Now we are using the machine to machine communication for the new applications with the help of IOT, where communication between the devices is on the internet only. Most of this kind of applications are happening on mobile based products only.
Our Embedded Training Institute in Bangalore :
So the topics what we have explained or discussed here are already have implemented on the design of firmware development, hardware, marketing of the embedded devices. There are lot researchers are working on all of these concepts to give much better n better results for the coming future. So, students who are looking for a career in the embedded systems field, they can build a bright future in this field. Embedded systems industry have a lot of other industries or in all most every industry we can give a touch of embedded systems. There are a lot of embedded systems training institutes in Bangalore or other cities of India. To find out best-embedded systems courses from fields is depends on your interest in the same. We Professional training institute giving industrial technology-oriented embedded training program in Bangalore. We giving a free career development counseling for those who are interested in this field.
