What's the general way to incorporate handwritten module with TSE ethernet?

Suppose we have handwritten IP module that continuously reads data from ADC, processes it and writes to some on-chip fifo. Now we want to send those data via Ethernet. I got impression the common w...

dagofff, the fastest solution is that was proposed by crevars. I'm using also a custom hardware for UDP generation, the transmission to the TSE Mac is done by SGDMA. The custom hardware has a Avalon Slave port which is connectet to the m_read port of the sgdma_tx. My design is based on TSE_SGDMA example. You can find that i.e. in C:\altera\72\nios2eds\examples\vhdl\niosII_stratixII_2s60_RoHS.

With a software based solution is a speed between ~30MBits/s and ~145MBits/s (according AN440, page 18) possible. The max speed I use in my hardware solution is about 640 MBit/s.

The best way may be you try to adapt the tse_optimized design according AN440. If the bandwith is to small than you must implement a hardware protocol engine.

here you can download AN440 and design files:
