20150052390 | Apparatus and Method for Microprocessor File System Protection - A system for providing protection to a processor system from the problems associated with power failures in the middle of processor operations is described. On detection of a power failure in the main power source, the processor power is maintained by means of a short-term secondary power source. Either immediately or after a momentary pause to override glitches, if power remains off the processor is notified that power will soon be removed and that an orderly shutdown is to take place. Once the protected system has completed its orderly shutdown, or after a length of time indicating that the orderly shutdown is improbable, power is removed from the system for a defined period and the system removes power from the protected processor system for at least a defined period of time, providing an assured hard restart. When external power is restored a normal running state is resumed after any power up sequencing. The orderly shutdown and hard reset can take place by command from the protected processor or system. A state machine is used to sequence the states in this process and control the transitions between states. | 02-19-2015 |
