Introduction
The MVME5100 is a state-of-the-art Single Board Computer. It
incorporates Motorola’s PowerPlus II architecture with a choice of
PowerPC processors—either Motorola’s MPC7400 with AltiVec™
technology for algorithmic intensive computations or the low-power
MPC750.
The MVME5100 incorporates a highly optimized PCI interface and
memory controller enabling up to 582MB/s memory read bandwidth and
640MB/s burst write bandwidth.
The on-board Hawk ASIC provides the bridge function between the
processor’s bus and the PCI bus. It provides 32-bit addressing and 64-bit
data; however, 64-bit addressing (dual address cycle) is not supported. The
ASIC also supports various processor external bus frequencies up to
100 MHz.
Note
Unless otherwise specified, the designation “MVME5100”
refers to all models of the MVME5100-series Single Board
Computers.
