Data storage system and method

摘要

The system (1) has an energy storage (5) storing energy supply after failure of a power supply for a data processing system (100) for a time period. A programmable logic unit (2) is attached to a bus system i.e. priority channel, that retrieves data of two data types (D1, D2) from a processor (101) of a data processing system (100). The logic unit selects the data of one of the data types and writes the data in a volatile memory (3) e.g. cache memory or RAM. The logic unit evaluates a signal that indicates failure of power supply of the data processing system. An independent claim is also included for a method for storing data.
