fast ethernet on altera FPGA

Hi Guys,

I need to develop a DAQ system that sends 10MB of data over an ethernet connection to a PC in 100-200 ms. My connection will be point to point, but on one side I have a standard PC. Do you think an approach with Altera FPGA is realistic?

I was thinking to a TSE insatiated out of a NIOS processor and a custom block of logic that feeds TSE with the transmitting data. Do you think this will be feasible?

I appreciate very much any suggestion from you.

Thanks a lot.

    Thanks Socrates,

    can you please help me figuring out the way to proceed?

    Mi idea is to put a TSE in a NIOSII system but break the standard datapath by

    inserting a custom module that gets data from an external memory, formats them in ethernet packets and send them to the TSE for transmission. What do you think about this?

    10MB data every 100ms is 100MB data every 1s, so 100MB/s = 800Mbps. Hardly possible, but only in hardware and using GbE link ofcourse.
