Address Translation Logic for Multi-Tenant Transaction Routing

The patent introduces an address decode and translate (ADT) logic module as an intermediary component within the adapter card or SOC. This ADT logic acts as a mediator between the host system's address space and the local address space of the adapter device, performing address translation and transaction decoding functions. By isolating the complex address management logic in a dedicated intermediary module, the main adapter card architecture remains relatively simple while achieving precise address translation capabilities.

The ADT logic is designed to autonomously perform address translation, transaction decoding, and anomaly detection without requiring external intervention. The logic automatically compares decoded addresses against configured address ranges, identifies transactions targeting unauthorized or non-existent resources, and can block suspicious transactions. This self-service capability enhances system security while minimizing operational complexity, as the security functions operate automatically without manual configuration or monitoring.

The system performs preliminary address decoding and range validation before fully processing transactions. The ADT logic pre-configures address ranges for valid resources and performs quick comparison checks against these pre-established ranges. By performing this preliminary filtering action, the system can rapidly identify and block transactions targeting unauthorized resources (potential DoS attacks) without requiring full-depth analysis of every transaction, thereby reducing overall processing energy consumption while maintaining high detection capability.
