Latest Patents

One of Feehrer's latest patents is titled "Apparatus and method for implementing fault resilient booting in a multi-processor system by using a flush command to control resetting of the processors and isolating failed processors." This invention focuses on enhancing the reliability of multi-processor systems during the booting process. The apparatus attempts a cold reset of the system, during which each processor performs a built-in self-test. It selects a boot strap processor to perform a warm reset, ensuring that any failed processors are tristated using a flush command. If no boot strap processor is available, the system repeats the attempt to establish one.

Another significant patent is "System and method for recovery from address errors." This invention describes a device and method for recovering from address errors detected on a local channel. The process involves reading the coherency states of cache memory lines and taking appropriate actions based on the detected states. If the data state consistency is unknown, the corresponding data in main memory is poisoned to prevent errors from propagating.
