Data processing system with fault detection for transactions
The patent US12072757B2 outlines a data processing system designed to enhance transaction management through a unique tagging mechanism. Central to the system is a transaction scheduler that processes transactions and a controller that manages transaction requests. The controller generates a unique tag value for each transaction request and loads it into the transaction scheduler. It monitors the execution of transactions by comparing the current unique tag value with those stored in the scheduler. If discrepancies arise—such as a mismatch after a transaction wins arbitration or a timeout due to processing delays—the system generates a fault. The claims detail various scenarios that trigger faults, including improper deallocation of transactions and unexpected execution orders.
Additionally, the patent describes methods for fault detection and handling within the data processing system. The controller can generate interrupt signals in response to detected faults, prompting a service routine for analysis. The system is designed to maintain operational integrity by allowing other components to function normally during core domain resets, provided the fault is not classified as a hard error. The claims also mention the use of error-correcting code (ECC) and lockstep processes to ensure data integrity during transactions. Overall, the patent presents a structured approach to managing transaction execution and fault detection, aiming to improve reliability in data processing systems.
