A comprehensive system-on-chip architecture guide detailing the deployment of hardware bus firewalls in ISO 26262 automotive and defense microelectronics.
Modern automotive and defense SoCs integrate hundreds of heterogeneous processing cores: application CPUs, real-time microcontrollers, DSPs, neural accelerators, and cryptographic engines all sharing unified on-chip interconnects. Software-based isolation is no longer sufficient to guarantee safety and security against sophisticated multi-vector attacks.
How on-chip firewalls directly satisfy automotive cybersecurity mandates (ISO/SAE 21434) by providing verifiable physical isolation between external-facing telematics units (cellular, V2X) and safety-critical powertrain and braking controllers.
Architectural blueprints for configuring AXI Interconnect firewalls, defining granular access matrices, configuring peripheral whitelist filters, and testing interconnect robustness using automated hardware fuzzing.
