E60, E61, E63, E64, E87, E90 - Motherboard With Processors
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2005 BMW 645Ci, 2005 BMW 545i, 2005 BMW 530i, 2005 BMW 525i, and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.
Construction
The motherboard contains 2 slots for PMC expansion cards (PCI Mezzanine Card). Besides the flash memory, there is a further slot holding the memory chip for CCC applications. Data is exchanged between the components and the central computing unit via the internal PCI bus (Peripheral Interconnect Bus). The PCI bus is configured for 32 bits and can transmit up to 133 Mbyte per second. The 2 drives are connected to the motherboard by IDE (Integrated Drive Electronics) interfaces.
The illustration shows the example of the CCC on the E60.
