Software Engineering for Embedded Systems, Training Workshop

The field of embedded software engineers has seen quite a resurgence over the past decade.

This is due in large part to the emergence of 5G technology, which has given rise to the Internet of Things (IoT) massive connectivity, and the coming of age of smart wearable devices.

Embedded systems are typically popular in medical science, consumer electronics, manufacturing science, aviation, automotive technology.

A typical embedded system requires a wide range of programming tools, microprocessors and operating systems. Embedded software engineering, performed by embedded software engineers, needs to be tailored to the needs of the hardware that it has to control and run on.

The software and operating system requirements of an embedded system is also different from a traditional computer based system. Typically embedded systems use basic embedded system software such as C, C++, ADA, etc. Some specialized embedded systems may use OS such as Windows CE, LINUX, TreadX, Nucleus RTOS, OSE, etc.

Embedded software engineering differs from traditional application development in terms of the additional consideration to external factors such as temperature and other environmental factors that may affect performance.

Like so many systems engineering areas, the embedded software engineer’s job has changed dramatically over the past two decades and continues to evolve.

In the early days of embedded systems, developers used “simple” 8-bit or 16-bit architectures that a developer could master over the course of several months during a development cycle. Over the past several years, many teams have moved to more complex 32-bit architectures.

They don’t just include a few peripherals for sampling sensors and communicating, but also hardware for USB, external memory, DMA, TCP/IP, Bluetooth, and many other peripherals that would take a developer perhaps years to truly master.

Bottom line: Embedded systems have started to become extremely complex

Embedded software is the first layer of code that runs on a device. You can think of it as BIOS on a PC. Embedded engineers write code, but unlike software engineers, they need a profound understand of the hardware it runs on — an embedded engineer knows the schematics of hardware and how chip datasheets relate to the code written for them.

Embedded software engineers determine the smallest possible number of drivers the device needs to run the software. Embedded software is generally self-contained and only runs a single program.

Just about all devices being produced today have underlying software that makes them run. In fact, you can think of everything from toasters and digital TVs to flashlights and smartwatches as computers.

This has become the area of focus among embedded software engineers. Some see the embedded software engineer profession as a kind of hybrid between electrical engineers and software engineers.
