A data processing apparatus is provided comprising a front-end interface electronically coupled to a main processor. The front-end interface is configured to receive data stored in a repository, in particular an external storage and/or a network, determine whether the data is a single-access data or a multiple-access data by analyzing an access parameter designating the data, route the multiple-access data for processing by the main processor, and route the single-access data for pre-processing by the front-end interface and routing results of the pre-processing to the main processor.
