The architecture must change to support xEV, AD, SOTA and
enable MaaS of the fleets while balancing system cost
› ADAS and AD requires
hierarchical architecture
› Manage complexity
introduced by
new/advanced
functionalities
› Address increased safety
and security requirements
› Increase flexibility and
enable “upgradability”
(SOTA)
› Optimize system cost at
low power consumption
Domain Control
Domain Integration
Zone Architecture
Car Computer
These approaches can
be clustered with good
approximation into the
following categories:

Freedom of interference
• Hypervisor / Virtualization
• Memory protection
Rich connectivity
• PCIe / xSPI
• High-speed TSN Ethernet
• Network bridges between Ethernet and CAN
• Automotive buses
• Sensors interfaces
• GPIO
• ADC
1 2 3
• DMIPS
• Booting Time
• Dedicated hardware accelerators
• Scalable family
