Software processing device with software actualization function

摘要

The software processing device has a memory divided into a main memory partition (6) and a standby memory partition (16) for holding 2 groups of software modules and their associated data respectively and a software actualization control device (24), with actualization of the new software in the standby memory partition updated using the old software stored in the main memory partition during execution of the latter, with transfer of data from the main memory partition to the standby memory partition via a transfer device (26). Also included are Independent claims for the following: (a) a distributed data processing system with a software actualization function; (b) a condition copying method for software actualization.
