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.
Freescale reserves the right to change the detail specifications as may be required
to permit improvements in the design of its products.
