processors can run MPC750 object code with no
modi
fi
cations; yet, they offer programmable
features that can be enabled for the system’s next
software release. In addition, the MPC74xx devices
are evidence of Motorola’s HiPerMOS process
technology advancements. With the help of smaller
submicron geometries, lower core voltages, copper
interconnect technology, and silicon-on-insulator
(SOI) process, the MPC74xx devices offer a
sizeable increase in operating frequency range over
their predecessors.
Motorola’s upcoming BookE devices, which will
offer enhanced integration, higher clock speeds,
and architectural features targeted speci
fi
cally at
embedded systems, will run 32-bit user-mode
software developed for either the MPC750 or the
MPC74xx device without modi
fi
cation. The
investment you make in application code today will
be preserved in G4 and beyond.
Migrating from the MPC750 to Motorola’s G4 may
be one small step for your engineering team, but it’s
one large step toward overcoming I/O bottlenecks
and maximizing your system performance.
