Embedded software in its basic nature is a software used to control devices not fully regarded as computers, these types of devices are called embedded systems. Synonym for such software is sometimes referred to as firmware.
With such devices, there are specific challenges and issues in their function. And where are issues, there is an embedded software development company that is specialized in resolving those problems.
In the following lines, we will address some of the major challenges of ESD in short notes.
Challenge #1 Stability
Stability is of supreme and greatest importance in the proper functioning of embedded systems. Unexpected behavior of a system poses some serious risks. End users are expecting proper functioning of embedded systems and their uniform behavior in order to perform necessary tasks without disruption.
Challenge #2 Safety
Safety is a specific feature of ES (embedded systems) due to their use associated with functionality in condemnatory environments. Software Development Life cycle specialized for embedded software is described by strict needs and constraints regarding quality and engineering expertise.
Challenge #3 Security
Security a major paramount of the digital world is getting more attention with every security breach and scandal in an online world. Risks are growing increasingly, especially for IoT devices which are getting more and more popular worldwide. Modern home appliances like washing machines, refrigerators are having connectivity features built in by default.
Challenge #4 Launch Phase
Tough indicators in embedded system development are most definitely time-to-market and time-to-revenue specifically for IoT branches. For this reason, applications and platforms are expected to support billions of IoT systems which are expected to circulate by 2020. Extreme flexibility and integration are required for fabrication of hardware components that are housing embedded systems. Longer IoT device lifespan, future updates, and releases are becoming an issue for component designers.
Challenge #5 Design Limitations
Most of the challenges in designing embedded systems have almost always been in the identical limiting requirements:
- Small-scale form factor.
- Low energy.
- Prolonged stable performance without upkeep.
Expanding market is demanding from designers to create more processing power and prolong the battery lives into spaces that are more compact, which is most of the time a tradeoff. Ultimately, in comparison of applications in IoT, there is an increasing demand for creating very scalable processor units ranging from inexpensive and low power consumption to topmost performance that are highly configurable. There is an identical demand for performance of system buses and memory caches.
Challenge #6 Integrity and Compatibility
Estimations are showing that currently most of the applications on the market are created and published by businesses younger than 3 years old. With their expertise in developing software, a good number of them are lacking experience in implementing and pushing updates to their applications in IoT environment, especially in regard to security regulations.
Expansion of IoT devices on the background of connectivity creates more pressure on their adaptive capability. Users need to be capable of managing the application via a simple UI and all available channels including over the air software updates that need ultimate compatibility through the entire ecosystem.
Integrity becomes a function of safety. To protect the IoT from attacks or being compromised, security must be implemented inside each of the devices at every level.
Key Issues of Embedded Software Development
Whether we like it or not, by 2021 the number of wirelessly connected devices by certain estimations will grow to 25 billion across the globe. Embedded solution developers are being faced with many issues throughout this way. We will not be covering the entirety of them in detail. So let’s just have a look at a few of them.
Pre-engineered software stacks are resolving the complexity of connectivity but only partially, the issue still remains for programmers to have enough skill and knowledge to understand a problem if certain modifications are required.
With IoT devices, the updates have to be delivered and pushed on their own without any of the users’ intervention.
Many embedded software developers state that each embedded project incurs additional costs for debugging taking roughly 40% of devs’ time.
Embedded systems are getting increasingly more independent from the hardware which they are placed into. They will no longer be characterized by hardware obstructions, becoming capable of doing any operation to achieve a certain objective. Hopefully, points described in this article will help you to understand some of the key issues and challenges ESD has and possibly make you more aware of how to tackle them.
