SoC Resource Partitioning With Contract-Based Secure Isolation

The patent combines multiple providers' resources onto a single SoC chip, merging previously separate ECUs and control units into one integrated device. This consolidation eliminates the need for complex external interfaces between multiple chips while maintaining security through virtualization and isolation mechanisms that allow each provider to retain control over their respective resources.

The patent segments the single SoC into multiple isolated domains or virtual environments, each controlled by a different provider. Through partitioning and virtualization techniques, each provider's resources are separated and protected within the unified chip, maintaining trust boundaries while enabling efficient on-chip communication without complex external interfaces.

The patent implements self-service mechanisms where each provider's resources automatically manage their own isolation and security requirements through embedded protection mechanisms. The system enables autonomous resource management where components self-regulate access and isolation without requiring complex external coordination, thereby maintaining efficiency while reducing the burden of isolation management.

The patent introduces intermediary management layers or virtualization components that mediate between different providers' resources on the single SoC. These intermediaries handle isolation and access control automatically, allowing efficient resource sharing while managing complexity through standardized mediation rather than direct complex interactions between all components.
