Embedded systems play a fundamental role in our everyday lives. They are at the heart of various products, machines and operations which allow us to keep up with the digitalisation of the modern world.
From medical devices and cars to home appliances, we’ll be discussing how embedded systems impact our daily lives.
Definition
So, what is an embedded system? It’s a micro-controller based system using a combination of hardware and software, which is designed to perform a particular function as part of a larger product.
These small-form computers can typically include microprocessors, graphics processing units (GPUs), volatile and non-volatile memory and input/output communication interfaces.
There are four different types of embedded systems, which are determined based on their performance and functional requirements. The types are:
- Real-time embedded systems
- Standalone embedded systems
- Network embedded systems
- Mobile embedded systems
Benefits
There are numerous benefits to embedded systems, with one being that they are designed to operate with little to no human intervention, meaning they are easy to manage and can function easily on their own.
They are made from relatively cheap materials which are reliable and long-lasting, so they don’t require much maintenance. Plus, many embedded systems which only deliver a single task work with fast performance to ensure optimum efficiency.
As they are smaller in size compared to a traditional computer, they are easily portable and take up little space. The hardware is also less costly, as embedded systems hardly require any changes, such as adding additional storage. This makes them suitable for most devices.
Washing machines
An example of an embedded system that we use and rely on regularly is a washing machine. Using real-time operating systems (RTOS), this home appliance has to execute demands within strict time limits.
Washing machines require a reliable operating system to help it function correctly – especially as they hold large amounts of water. With more modern washing machines now available, some come with a display that allows you to gain further insight into the length of the cycle and other additional settings and features.
Plus, if your washing machine has Bluetooth, you’ll be able to control your machine with a mobile app.
Medical devices
Within the healthcare industry, embedded systems are primarily used for data storage. They can help accurately track patients who need additional care and close monitoring, whether they’re at home or in the hospital.
Diagnostic tools have come on leaps and bounds thanks to the use of technology. Embedded systems are used in almost all imaging systems, including PET scans, CT scans and MRIs. Plus, many biomedical sensors rely on embedded systems, helping doctors monitor patients’ health and making important treatment decisions.
