Description

burst_short_in

Input

4

Encodes the BurstShort parameter for the IP

core.
The 50G Interlaken IP core supports the

following valid value for this parameter:
1: 32 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. If you

disable enhanced scheduling, performance is

non-optimal.
1: 32 bytes
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.
