An embedded system is a special computer system that becomes an integral part of the hardware. Every embedded system is depending on a microprocessor or a microcontroller that is programmed for achieving specific tasks.
It has to fulfill a lot of specific and difficult needs that vary depending on the device’s task.. Nowadays, we can find embedded systems everywhere – from calculators to airplanes. The reason for this comes from the idea of modern technology – that everything should be “smart” and automatic.
What Are The Challenges Of Embedded Systems Development?
The main rule of manufacturing embedded systems states that the less complex the embedded system the more reliable and fast it becomes. But it cannot always be accomplished due to specific requirements that some of the devices hold. What is more, new technologies emerge so fast that sometimes the developers find it hard to catch up. Nevertheless, the main focus of engineers while designing and manufacturing embedded systems is to make them as reliable, fast, and accurate as possible. It often is a big challenge to achieve this level of perfection.
The First challenge – Stability and Compatibility
One of the main characteristics of embedded systems is, of course, that they are embedded. That fact carries many consequences. It determines that the device cannot exist on its own; it has to be compatible with the rest of the product and stable enough to use it without any errors. That is why it is important that during the process of manufacturing, there are several tests run to make sure that the product is usable, solid, and reliable.
The second challenge – safety and security
Safety in this context regards the physical aspects of the product, such as maintaining high functionality in hard environmental conditions, for example, working in high/low temperatures or underwater.
Whereas the term “security” refers to the internet-based threats that are present while the device is connected to the web. A lot of home appliances have this feature now in the name of being “smart.” Modern devices became multifunctional, and even refrigerators can have online features nowadays
The third challenge – debugging and updating
As time passes, the “smart” devices have to be updated, most preferably remotely. Developers have to take that into consideration during process of embedded systems development to avoid errors and later dissatisfaction of customers.
But the most difficulties involve the process of debugging. Unfortunately, bugs are considered to be a large problem, but they concern almost every embedded system that is regarded to be complex. Debugging is not as simple as it may seem; it is known to consume almost half of the time of the developers while working on a device. But it is worth the time to solve this problem well because when it is put on the market, usually it gets too late to correct it. When it comes to that topic, customers can be unforgiving.
