DISTURBANCE FREE UPDATE OF DATA

摘要

To improve the efficiency for an update process in a software processing device with a plurality of memory partitions (4, 14), it is proposed to continue the execution of old software on original data stored in a first memory partition (4) and to update new software and related data in a second memory partition (14). In case the same state for data of old and new software is achieved (S4), an instant switch of services to the new software as far as the same state is achieved (S5) takes place. This processing is repeated (S6) until no data to be transferred remains (S6) in the first memory partition. Thus, the present invention allows for a considerable improvement of the update efficiency with reduced disturbances during data transfer.
