Embedded systems are everywhere. They are the brains behind the basic functions that make todays lives easier. Whether it’s a simple light switch or a complex car engine, embedded systems are everywhere and they need to be reliable, efficient and secure.
Here is how to improve an embedded computer system:
Start Measuring Key Metrics and Drivers
The first step to improving an embedded system is to start measuring the key metrics that drive the project. Start by looking at what your customers (internal or external) want from your system. What do they want it to do? How fast does it need to run? What is the environment like where it will be used? Once you have an idea of what your customers want from your product, you can start thinking about how to build a better embedded system that meets their needs.
Start Having Code Reviews
Code reviews are a great way to improve software quality and reduce bugs in your code base. When you have multiple engineers working on the same code, there are bound to be some differences between their styles and approaches — which means some code may be more secure than others and some code may have better performance characteristics than others. Code reviews help bring these differences out into the open so they can be discussed and improved upon before they become problems down the road when the code base is much larger than just one person’s work area.
Master Debugging Skills
Debugging is one of the most important skills in embedded systems development. You will always be faced with bugs, and you need to know how to find them and fix them.
It’s a good idea to learn how to use an integrated development environment (IDE) that has debugging capabilities built-in, such as GCC or Visual Studio. These tools can help you quickly find where in your code a problem occurs and then set breakpoints so that you can step through the code until you get to the problem area.
Start Automating Testing
Automated testing is important for embedded systems because it makes it easier to test many scenarios and ensure that everything is working correctly. You can write tests for all of your code or just use open source testing tools like Selenium WebDriver or Robot Framework if you don’t have time or resources to write your own tests. These tools allow you to write tests using a script language and then run them against real devices over Wi-Fi or Ethernet connections without having physical access to the device itself!
Secure code and data protection
The most important thing that you can do to improve your embedded system is to make sure that it is secure. This means making sure that all the code, data and other resources are protected from unauthorized access. It also means taking advantage of security features such as encryption and password protection.
Efficient power management
An embedded system must be able to run on battery power if possible. This means reducing power consumption wherever possible, such as by turning off parts of the system when they are not needed or by using sleep modes when they are not being used. It also means making sure that any batteries are properly charged and maintained so they will last longer.
There are several reasons for the necessity to improve embedded systems. First, the industry is changing from Sequential design methods to combinational design methods. Second, the improvements in software technology should be used. It is needed to reduce the number of man hours required for development. The next step towards better software is testing of systems incorporating those software components without altering circuit functionality and endurance testing of such components to detect failures.
