IXP2400 Memory
The
Memory
tab on the
System Configuration
property sheet supports the configuration of
simulator memory (see
). There are some variations on the screen depending on which
network processor is being configured. For the IXP2400 the following simulator conditions apply:
•
No SRAM channel can exceed 64 MB, so the
Part count
option of
2
becomes unavailable if
the
Part size
is 64.
•
The simulator must have a populated SRAM channel. Zero memory cannot be configured,
therefore there is no option for a zero
Part size
or
Part count
.
There are two channels available for configuring the IXP2400 SRAM memory.
•
The DRAM size is currently limited to 64 MB by the simulator, so there is only one DRAM
size option available.
Channel count
is unavailable for the DRAM.
•
Each of the two SRAM channels may be configured independently.
