IXP2800 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 IXP2800 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 four channels available for configuring the IXP2800 SRAM memory.
•
The DRAM
Chan size
value multiplied by the
Chan count
value yields the total DRAM
memory available in the simulator. Between 1 and 3 DRAM channels are possible. The
DRAM size is limited to 2046 MB, so the available channel count value options become
limited at the higher channel sizes.
•
Each of the four SRAM channels may be configured independently.
