ABSTRACT:
A recovery process for embedded processors monitors other processes in the system. Each process may specify a recovery policy residing in nonvolatile electronic memory that preferably includes a recovery count, a recovery time, and a recovery action. If a process terminates unexpectedly, the recovery process determines whether the process had a corresponding recovery policy. If not, the recovery process does not recover the process. If the process has a corresponding recovery policy, the recovery process determines whether it can recover the process by examining the recovery count and recovery time specified in the recovery policy. If the process can be recovered, the recovery process performs the recovery action specified in the corresponding recovery policy. If the process cannot be recovered, the recovery process resets the system. In this manner, a single process may be recovered by the recovery process without user intervention and without affecting other processes running on the system, and without performing a reset of the entire system.
