Functional Description

The MVME7100ET is a VMEbus board based on the MC8640D and MC8641D Integrated
Processors. The MVME7100ET provides 2eSST VMEbus interfaces, dual 64-bit/100MHz
PMC sites, 128MB of NOR flash and up to 8GB of NAND flash, up to 4GB of DDR2
SDRAM, quad 10/100/1000 Ethernet, and five serial ports. The MVME7100ET supports
front and rear I/O with access to the rear I/O via the MVME7100ET transition module.
The MVME7100ET provides front panel access to one serial port with a mini DB-9
connector and two 10/100/1000 Ethernet ports with two RJ-45 connectors. The front panel
includes a fail indicator LED, user-defined indicator LED, and a reset/abort switch.
The MVME721ET 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 MVME7100ET programming model is based on the MC864xD local memory map,
which 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 MC864xD DDR2 SDRAM and local bus memory controllers exists in this memory map
in addition to all memory mapped configuration, control, and status registers. Memory
maps and registers are described in
Descriptions.
