Any success? Thanks, Gilad. ^ permalink raw reply [flat|nested] 4+ messages in thread

Any success? Just remember that the Au1x00 boards are 32-bit , 33 MHz, 3.3V PCI, so choose your boards accordingly. Please don't expect the Au1x00 to run the TCP/IP stack anywhere near Gigabit speeds ..... :-) Read the networking mailing lists for the actual performance of various systems at these network speeds. Thanks. -- Dan ^ permalink raw reply [flat|nested] 4+ messages in thread

Please don't expect the > Au1x00 to run the TCP/IP stack anywhere near Gigabit speeds ..... :-) We have researching this topic for a little while, particularly from the FPGA standpoint. Although not specific to MIPS, I offer a few links which discuss the considerations for successfully sustaining gigabit ethernet transport. The "Gigabit System Reference Design", pg. 49 offers some benchmarks obtained using MontaVista Linux on a PowerPC 405. Key takeaways are that the data payload must not be handled by the stack (DMA direct from framebuffer/fifo/sdram) and must use jumbo (5000,9000) ethernet frames.
