Functional Description

The MVME7100 is a VMEbus board based on the MC8640D and MC8641D Integrated
Processors. The MVME7100 provides USB 2.0, and 2eSST VMEbus interfaces, dual
64-bit/100MHz PMC sites, 128MB of NOR flash and up to 32GB of NAND flash, up to 4GB
of DDR2 SDRAM, quad 10/100/1000 Ethernet, and five serial ports. The MVME7100
supports front and rear I/O with access to the rear I/O via the MVME7216E transition
module.
The MVME7100 provides front panel access to one serial port with a mini DB-9 connector,
two 10/100/1000 Ethernet ports with two RJ-45 connectors, and one USB port with one
type A connector. The front panel includes a fail indicator LED, user-defined indicator LED,
and a reset/abort switch.
The MVME7216E transition module provides rear panel access to four serial ports with one
RJ-45 connector per port and two 10/100/1000 Ethernet ports with two RJ-45 connectors.
The RTM also provides two planar connectors for one PIM with front I/O.

Programming Model

The MVME7100 programming model is based on the MC864
refers to the 36-bit address space seen by the processor as it accesses memory and I/O
space. DMA engines also see the same local memory map. All memory accessed by the
MC864 D DDR2 SDRAM and local bus memory controllers exists in this memory map in
x
addition to all memory mapped configuration, control, and status registers. Memory maps
and registers are described in
Descriptions.
