Description
burst_max_in
Input
4
Encodes the BurstMax parameter for the IP
core. The actual value of the BurstMax
parameter must be a multiple of 64 bytes. While
traffic is present, this input signal should
remain static. However, when no traffic is
present, you can modify the value of the
burst_
max_in
signal to modify the BurstMax value of
the IP core.
The 100G InterlakenIP core supports the
following valid values for this signal:
2: 128 bytes
4: 256 bytes
8: 512 bytes
burst_short_in
Input
4
Encodes the BurstShort parameter for the IP
core.
The 100G Interlaken IP core supports the
following valid value for this parameter:
2: 64 bytes
In general, the presence of the BurstMin
parameter makes the BurstShort parameter
obsolete.
burst_min_in
Input
4
Encodes the BurstMin parameter for the IP
core.
The IP core supports the following valid values
for this signal:
0: Disable optional enhanced scheduling. Altera
recommends you do not drive this value in
variations in dual segment mode. If you disable
enhanced scheduling, performance is non-
optimal.
2: 64 bytes
4: 128 bytes
The BurstMin parameter should have a value
that is less than or equal to half of the value of
the BurstMax parameter.
Altera recommends that you modify the value
of this input signal only when no traffic is
present on the TX user data interface. You do
not need to reset the IP core.
