Standard frameworks to support vehicle architecture and IoT
This section covers the internal architecture of the ADC/CDC/VDC ECUs which comprise microcontrollers and SoCs. The variation in the number of microcontrollers and SoCs is based on functionalities, features supported, and the required number of inputs and outputs. Before delving into the standard framework, we’ll provide a high-level overview of the domain controller to understand where these frameworks are applied.
A high-level overview of the domain controller
Figure 3.5 shows a domain controller that encompasses both a microcontroller and a SoC. Microcontrollers are capable of handling small, time-critical applications such as power management and communication stacks such as CAN. On the other hand, SoCs are capable of handling resource-intensive applications such as navigation, media, OTA, and remote diagnostics, all of which require more processing time and memory.
The interaction between the microcontroller...
