This section provides a high-level overview of the MPC8641
and MPC8641D features. When referring to the MPC8641
throughout the document, the functionality described applies
to both the MPC8641 and the MPC8641D. Any differences
specific to the MPC8641D are noted.
Figure 1 shows the major functional units within the
MPC8641 and MPC8641D. The major difference between
the MPC8641 and MPC8641D is that there are two cores on
the MPC8641D.
