Embedded systems and hardware architecture
An embedded system is a combination of hardware and software that is designed to perform a specific task. The embedded hardware is usually based on a microcontroller and microprocessors. In this section, we will take a quick look at the different architectural elements of an embedded system, including memory and communication between these devices. Pretty much everything that we use on a day-to-day basis is an embedded device, including mobile phones, DVD players, GPS systems, and intelligent voice assistants such as Alexa and other hardware-based solutions.
Embedded system basic architecture
The basic architecture of an embedded system typically includes a hardware and software component. Figure 14.1 depicts the typical architecture components of a simple embedded device:
