I have a FIFO module running at 24MHz, producing 1 byte per clock. Then it produces 24MB/s. I need to send this data to PC through USB or Ethernet.

How can I achieve this? Doesn't exist some USB controller or something? Searching in the web I read about I2C but it seems very slow for my purposes.

This is what I'd like. However I'm able to reduce the amount of data to 6MB/s if no solution exists for the previous requirement.

  • \$\begingroup\$ Just try to give an indication of how much data you are trying to send into the PC. \$\endgroup\$

  • \$\begingroup\$ The indication is 6MB/s. Below I sacrifice too much quality. However I just found this one ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT245R.pdf It says "full speed USB 2.0". Do you think it could be what I'm looking for? \$\endgroup\$

    \$\begingroup\$ The software radio people with fairly similar needs manage to fill up USB2 pipes to a high degree using things like the Cypress FX2 parts - and presumably today the FX3. \$\endgroup\$
