Gigabit-MAC-IP-Core-Throughput

Another Topic.....

I have analysed a Gigabit-MAC-IP-Core:

Is it possible, that the Core received following values?

The Burst were generated by a Gigabit-Net-Analyzer and transmitted over a Cat5e-Cable.

So, I transmitted for example a burst with 100 Frames.

The Interframe Gaps were justified with 96 ns, 96 µs, 960µs and 4,8 ms.

Only once (4,8 ms and Framelength = 64 Byte) the Core recognized all transmiited frames.

If the framelength or the interframe gap is increased frames got lost....

So, are theses results ok?

In my opinion, the core isn`t able to work in Gigabit-Mode, is it?

    Hi Dubbi1900,

    which Gigabit MAC IP Core did you use?

    In fact I'm thinking about using such an IP with NIOS II, but I need to know the level of SW support provided by ALtera.

    I do not know what your problem may be, but maybe your Nios does not manage to execute quickly enough.
