We've found even a 16 bit CPU @ 18MHz (the c16x) barely does the job. We really need to do some thourough optimalisation to get a decent performance. Also the Ethernet hardware to CPU interface needs to be at least 16 bit wide, and preferably using DMA. (we're stuck with PIO, thus this eats a lot of cycles) You possibly need a high clock frequency with the M16 (they go upto 32Mhz?) or look at a 32 bit controller such as coldfire, ARM7 etc. > I have found some ports in contrib-0.7.1-20040319.tar.gz; are there other > ports available? This old tarball is only made available for historical reasons, try using CVS access for the later releases (1.1.1) or the latest version.
