PM603/604 Processor/Memory Mezzanine Module
3-24
The MVME1600-001 base board supplies a
14-pin combined LED-mezzanine/remote-reset connector, J1. When J1 is
used as a remote reset connector with the LED mezzanine removed, the
signal can be cabled to an external speaker to obtain a
SPEAKER_OUT
beep tone. For the pin assignments of J1, refer to Table 1-2.
Like the MVME1600-001 base board, the MVME1600-011 supplies a
signal to the 14-pin LED mezzanine connector, J1. Unlike
SPEAKER_OUT
the MVME1600-001 base board, the MVME1600-011 also applies the
signal to its dedicated remote status and control
SPEAKER_OUT
connector, J4. The LED mezzanine need not be removed to cable the
signal to an external speaker. For the pin assignments of
SPEAKER_OUT
J4, refer to Table 1-3.
The PM603 or PM604 is the processor/memory mezzanine module that
(together with an LED mezzanine, an optional RAM104 DRAM module,
and an optional PCI mezzanine card) plugs into the MVME1600-001 or
MVME1600-011 base board to make a complete single-board computer.
See Figure 1-10.
You have the choice of a PowerPC603™ module (the PM603) or a
PowerPC604™ module (the PM604) with from 8MB to 64MB of DRAM,
or up to 128MB of DRAM with a RAM104. 256KB of L2 cache is
available as an option. There is no parity or ECC protection on the DRAM.
The PowerPC603 is a 64-bit processor with 16KB or 32KB on-chip cache
(8KB/16KB data cache and 8KB/16KB instruction cache). The
PowerPC604 is a 64-bit processor with 32 KB on-chip cache (16KB data
cache and 16KB instruction cache).
The MPC105 bridge/memory controller located on the processor/memory
mezzanine provides the bridge between the PowerPC microprocessor bus
and the PCI local bus. The memory is kept on the processor bus to get the
optimum performance from the designs. Electrically, the
processor/memory module is a PCI connection.
