Abstract:
1. An apparatus of managing a reconfiguration data memory, comprising: a server including a configuration data storage unit, a temporary storage unit, and a target system connection unit; and a target system that is connected to the server through a wired/wireless Internet, the target system including a system on chip having an internal memory and an external memory, the target system further including a preservation data temporary storage part that temporarily stores preservation data in the internal and external memories before the preservation data is sent to the temporary storage unit, the target system further includes a reconfiguration request processing part which includes a preservation data encoding part that encodes the preservation data such that it is secure and then sends the encoded preservation data to the temporary storage unit, wherein the target system further includes a system memory judgment unit which comprises a memory type judging part that determines which of the internal and external memories stores the preservation data by detecting which of the internal or external memories is either a flash memory or an Electrically Erasable Programmable Read-Only Memory (EEPROM) and designating the flash memories and the EEPROMs as containing the preservation data; and wherein the server stores configuration data required for reconfiguration of the target system in the configuration data storage unit, the server transfers the configuration data to the target system through the target system connection unit at the request of the target system, the server calls preservation data stored in the internal and external memories of the target system to store the preservation data in the temporary storage unit, the preservation data being data required for operation of the target system before and after the reconfiguration, the temporary storage unit separate from the target system, the server performs the reconfiguration of the target system by executing the configuration data stored in the internal and external memories of the target system, and the server returns the preservation data from the temporary storage unit to its original position in the target system in response to notification from the target system that the reconfiguration of the target system is finished, wherein the target system connection unit comprises: a temporary storage calling part that returns the preservation data stored in the temporary storage unit to the target system when the reconfiguration of the target system is completed; and a memory state judgment part that detects the last piece of data of the configuration data being received and executed and, when it judges based on this detection that the reconfiguration is completed, calls the temporary storage calling part.
