Overview
The MPC8640 processor family integrates either
one or two Power Architecture™ e600 processor
cores with system logic required for networking,
storage, wireless infrastructure, and
general-purpose embedded applications. The
MPC8640 integrates one e600 core while the
MPC8640D integrates two cores.
This section provides a high-level overview of the
MPC8640 and MPC8640D features. When
referring to the MPC8640 throughout the
document, the functionality described applies to
both the MPC8640 and the MPC8640D. Any
differences specific to the MPC8640D are noted.
Figure 1
shows the major functional units within
the MPC8640 and MPC8640D. The major
difference between the MPC8640 and MPC8640D
is that there are two cores on the MPC8640D.
