Hi, I have the dsp development kit, cyclone iii edition (http://www.altera.com/products/devkits/altera/kit-cyc3-dsp.html). How can I use the Ethernet? In my altera > 80 > ip Directory I have triple_speed_ethernet. Will that work with this board? Or will I need additional IP-Cores? Will they also be shipped with my dev. kit? And are there IP-Cores for USB-Communication? Kind regards, Stefan__

Yes you can use triple_speed_ethernet from your quartus installation directory. It will shipped wit open core pulse feature enable so that without license you will able generate timelimited sof file. There is no any core require to communicate with PC. For USB IP Core, there is in built IP core shipped with Quartus software desiged from SLS. (altera -> 80 -> ip -> SLS). Regards, Hardik

Thanks for your response! But what about the avalon stream interface? Should I use this, too? And is there any possibility to make that Ethernet stuff a little bit more simple?

Yes you need to use that interface to send your Ethernet packets. It is rather simple to use.

--- Quote Start --- Yes you need to use that interface to send your Ethernet packets. It is rather simple to use. --- Quote End --- But it is only for unidirectional communication: --- Quote Start --- You can use Avalon Streaming (Avalon-ST) interfaces for components that drive high bandwidth, low latency, unidirectional data. --- Quote End --- (Source: http://www.altera.com/literature/manual/mnl_avalon_spec.pdf) Is there also something for bidirectional data?

No there isn't. The Triple Speed Ethernet uses two Avalon streams: a source for received packets and a sink for packets to transmit.

Sorry, I don't see anything wrong. Are you sure the PC is sending valid packets? The contrary would be very unlikely, but I don't see anything else...

is marvell 88e1111 hardware programmable or software?

I have a similar task. I would like to use the HSMC cards A/D ports to capture a Signal continuously and send it via ethernet to my PC.
Is that possible???
@stefan___: how did your project work out? Is it possible to send me some of the work you did?

@freelancer We are using DM648 on our customized board. The Marvell Alaska 88e1111 is used as PHY to establish communication b/w to nets to transmit TCP/IP packets. We have completed the Autonegotiation now working on packet send and receive. Please relate your project so that we can better communivate and share information.

A base band radio frequency signal will be captured and connected to an A/D Port on the HSMC Mezzanine Data Conversion Board which is connected to the Port A of the Cyclone III 3C120 Development Board.
From there I want it to pass on the signal using the Marvell 88E1111 PHY to send it to a PC where I can store the data in a file.

I don't have any experience on socket programming. I also havn't used a soft core (Nios II) before.

There a very view examples about the RGMII which are acually explained.

@danish2010: how is your progress? are you finished yet?
I'm now using the triple speed ethernet design example in the NIOS II EDS installation directory and modifying it. Is there a way to get around the license for the TSE Megacore IP ??
