Hardware design is viewed as the most essential component in developing embedded IoT devices in order to allow for the ultimate success of the product. The hardware design and development process are faced with many challenges while ensuring that the embedded product meets the necessary functionality, is dependable and secure, and consumes less power.
With the rapid development of connected devices, there has been huge growth for the embedded systems market as an overall result of advances in IoT. IoT or Internet of Things is a direct process where devices are set up with actuators, sensors, and processors involving hardware design and development, web APIs, software systems, and protocols which as a group act to become a connected arena making up the embedded system. The environment of connectivity enables technology to connect throughout multiple platforms, devices, and networks in order to develop a communication web changing digital interaction globally. Designing these hardware systems is a complex process.
Difficulties Faced With Designing Hardware
Considerable, intense thought and planning go into hardware design and development for embedded devices within IoT as it is fraught with many challenges.
Lack of flexibility is a concern in developing IoT embedded systems for several reasons:
- Difficulties ensuring integration is smooth for new services.
- Issues with adapting to varying environments.
- Hardware/software facilities changing often.
- Packaging/integration issues with smaller size chip that offers lower weight as well as less consumption of power.
- Being able to carry out awareness operations for energy.
Security in the real-time embedded arena is imperative for all of the IoT hardware devices. With resource-constraints as well as insecure physical situations that embedded components operate in, there are many security issues. The requirement is that they be designed and put into place as dependably and securely as possible using cryptographic algorithms and the ultimate in security protocol from the time of prototype all the way to deployment.
The functional safety of a device is considered to be a major part of the overall product’s safety. An embedded system is meant to meet all of the functional safety requirements as the ‘generalized control system’ where many different control actions take place requiring reconfiguration, autonomy, fault-tolerance, safety, and a need to eliminate any and all unacceptable risk factors.
Aside from the flexibility aspect, the embedded system is constrained due to expense. There is always a need in embedded hardware design and development process to find a better means from prototype up through the deployment process in an effort to maintain the cost optimality of the digital components as well as the quantity required for production.
It is just as imperative for the design and development team to coordinate effectively in order that the products are brought to the market at the appropriate time.
Hardware design and development is not a simple process. There are embedded systems surrounding us which have the capability of performing a vast array of unique operations. If your Wi-Fi router is operating at normal capacity the moment that you flip it on, you know that there was a designer who worked super hard to make that happen flawlessly. A deep understanding for hardware design and development process pertaining to the scenarios of the real-world where your electronic devices are going to be used is crucial.
