Altera's Ethernet core is even more expensive that Xilinx's. The one from OpenCores is looking more attractive all the time. Now I just need to build a PHY module for use with the Burched board. I think I'll use the Level One (Intel) LXT972. ###### From: "Martin Schoeberl" Newsgroups: comp.arch.fpga References: <99b0d5ad.0304091327.3088fc3a@posting.google.com> Subject: Re: Ethernet MAC (was Re: Cheap(er) FPGA configuration?)

As you need a PHY modul I think it does not make sense to implement MAC in the FPGA. You get an ethernet chip for a few $ with PHY, MAC internal memory buffers. You save a lot of LEs in the FPGA. I'm using the CS8900. Very simple to connect to the FPGA and good application notes. I ported the Linux driver to Java. If you need a connection diagram or the Java driver you can find it on my website :-) Martin -------------------------------------------------------- JOP - a Java Processor core for FPGAs now on Cyclone: http://www.jopdesign.com/cyclone/ ###### From: Petter Gustad Newsgroups: comp.arch.fpga Subject: Re: Ethernet MAC (was Re: Cheap(er) FPGA configuration?)

There's also support for a CS8900 in NIOS/SOPC Builder. Petter -- ________________________________________________________________________ Petter Gustad 8'h2B | ~8'h2B http://www.gustad.com/petter
