Hardware design challenges of the Embedded System and IoT

 As a result of the rising acceptance of new technologies and the deployment of new applications, embedded system designers confront a number of challenges in terms of flexibility while building Embedded IoT systems, including the following:

” There are difficulties in guaranteeing the seamless integration of new services.

” Having trouble adjusting to new situations

” Changes in hardware and software facilities on a regular basis

” Packaging and integration issues with a small-size chip that is light in weight and consumes little power are being investigated.

” Performing energy awareness operations, among other things.

All Internet of Things hardware components must be able to operate safely in a real-time embedded environment. Because all embedded components work in extremely resource-constrained and physically unsafe environments, engineers frequently encounter difficulties in assuring the security of these Embedded components. 

These systems must be developed and implemented in such a way that they are resilient and dependable, and they must also be secure, using cryptographic methods and security protocols to do this. Different ways are used to protect all the components of embedded systems, from their conception through their final deployment.

The power consumption of microprocessor hardware design, which is essential for obtaining the greatest performance possible from real-time applications and devices, is another progressively irritating restriction.  What continues to be a challenge is determining how to install an embedded system that can manage an increasing number of transistors while yet keeping an acceptable power consumption ratio.  

To ensure a trustworthy product design, other challenges include undertaking in-depth testing, verification, and validation on the product.

Device Driver Testing: Device drivers testing is comparable to all other forms of testing in that embedded developers employ hardware-based test tools. This refers to the embedded hardware that has been tested to ensure that the system’s performance, consistency, and validation meet the requirements of the product.

“ Verification is the process of determining whether or not functional verification has been implemented successfully.

“ Validation refers to the process of determining if a product meets the requirements and meets all of the applicable quality standards.

“ Failure of Safety-Critical Embedded Systems to Provide Adequate Functional Safety

“ The functional safety of a product is regarded to be a component of the overall safety of the product. For functional safety purposes, embedded systems are regarded as generalised control systems that perform a variety of control functions that necessitate autonomy, reconfigurability, safety, fault-tolerance, and the elimination of all unacceptable risks in order to comply with regulatory requirements. These factors have a significant impact on their employment in applications where a large number of functional loops compete for the design of computing resources, resulting in a variety of timing and task-scheduling issues that must be addressed.

Aside from their inherent flexibility and security, embedded systems are severely confined by their financial constraints.

With digital electronic components and large production quantities, there is a growing need to develop better approaches to handle the cost modelling and optimality associated with embedded hardware design from the development to the deployment cycle. This is especially true in embedded hardware design. It is also the responsibility of hardware/software code designers to tackle the challenge of design time and bring embedded devices to market at the appropriate time frame.

A wide range of embedded systems can be found throughout our daily lives in the form of commercial systems such as vending machines, smart vending machines, air conditioning controllers, connected cars, hotel bill printers and other similar devices. These embedded systems are capable of performing a wide range of operations.
