TCP/IP Memory Footprint

Ryan Brown

How big is the TCP/IP implementation in the RL-ARM
RealView® Real-Time Library?

http://www.keil.com/arm/rl-arm/

500 bytes is not a realistic RAM footprint for TCP/IP. My company is currently deciding on whether to implement ethernet. Any help would be appreciated.

    That helps, but what about the code that actually runs the TCP/IP stack, as in ethernet? The second article looks like we can get the IP communucation RAM usage down to 4KB? We just need to communicate via IP and a small FTP server, which I assume would be:

    TFTP Server 20,016 Bytes ROM 24,312 Bytes RAM

    + the 4KB minimum. Is this correct?

    Thanks for any help in advance!
