Functional Description

The MVME4100 VMEbus board is based on the MPC8548E system-on-chip (SoC)
processor. The MVME4100 provides front panel access to one serial port with a micro 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 transition module also provides two planar connectors for one PIM with front I/O.

MVME7216E transition module is shown in the Transition Module section of the
MVME4100 Single Board Computer Installation and Use manual.

Programming Model

The MVME4100 programming model is based on the MPC8548E local memory map, which
refers to the 32-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
MPC8548E 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.
