Fixed virtual Platform


in the DS-5 I have some pre installed FVP (e.g. VE_Cortex_A9x4). I understood these FVP are somehow related to a Virtual Express hardware platform. But I don't understand where do I get the configuration information of the FVP? E.g. if I have a Fixed Virtual Platform simulating a real world target how do I know e.g. how much memory and what peripherals are simulated?
