Current Automotive Compute Architectures

Automotive compute architectures have evolved significantly to accommodate the increasing demand for sophisticated in-vehicle technologies. Centralized, zonal, and domain-based designs represent the primary approaches to integrating computing power within vehicles, each offering unique benefits and challenges.

• Centralized Architecture: Centralized systems consolidate computing resources into a single, powerful unit, simplifying wiring and reducing complexity. This approach supports advanced applications, such as autonomous driving, by centralizing data processing and decision-making.
• Zonal Architecture: Zonal architectures distribute computing resources across different vehicle zones, optimizing data processing by locality. This design enhances system scalability and flexibility, allowing for incremental upgrades and the addition of new functionalities.
• Domain-based Architecture: Domain-based systems group functions by domain (e.g., infotainment, ADAS, powertrain) with dedicated controllers. This segregation ensures optimized performance and reliability for specific tasks but can lead to redundancies and higher costs.

Chiplet Systems emerge as a solution to enhance modularity and scalability in automotive compute architectures. By disaggregating System-on-Chips (SoCs) into smaller, functional units (Chiplets), manufacturers can tailor hardware designs to specific requirements, achieving higher modularity and integration. This approach not only facilitates customization for different vehicle models but also enables a more agile response to technological advancements and market demands.
