Honored ContributorHi,
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__
Honored ContributorYes 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, HardikHonored ContributorThanks 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?Honored ContributorYes you need to use that interface to send your Ethernet packets. It is rather simple to use.
Honored ContributorHonored ContributorNo there isn't. The Triple Speed Ethernet uses two Avalon streams: a source for received packets and a sink for packets to transmit.
Honored ContributorWhere can I get this avalon ethernet core?
At opencores.org I find some Ethernet Projects, but which of them is the right one...? And is it for GigaBit Ethernet? Maybe I should ask in another way: Which is the best possibility to communicate from Cyclone III Board to PC via Ethernet?Honored ContributorThis is the Altera Triple Speed Ethernet, available in SOPC builder, or seperately from the MegaWizard in Quartus. But I thought you found it, according to your first post.
I don't know what you mean by "best", it depends on your needs and resources. The easiest way would be to use a Nios CPU and an operating system with a TCP/IP stack. Without the Nios you'll need to code at least the ARP and UDP/IP protocols in hardware.Honored ContributorHonored ContributorYou can use C-2-H feature for converting your Nios C code into hardware. Using this all your c code convert into hardware block by altera tools and surly you will get the speed. But condition is that your c code is without any altera API ( like IORD, IOWR etc... ).
Honored ContributorI'd look at the udp offload (http://www.nioswiki.com/exampledesigns/nios2udpoffloadexample) example on the Wiki. That should give you the performance you desire.
