1.1 Features
The MVME5100 is a state-of-the-art Single Board Computer. It incorporates Artesyn
Embedded Technologies - Embedded Computing’s PowerPlus II architecture with a choice of
PowerPC processors—either Artesyn Embedded Technologies - Embedded Computing’s
MPC7410 with AltiVec™ technology for algorithmic intensive computations or the low-power
MPC750 or MPC755.
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.
The following table lists the key features of the MVME5100:
Unless otherwise specified, the designation “MVME5100” refers to all models of the
MVME5100-series Single Board Computers.
