Lexra LX5820 documentation
I was wondering if anyone had any documentation lying around for the Lexra LX5820? Far from being dead it's used in Realtek's RTL8181 802.11b access point SoC.
I am finding it very difficult to come across any details on just how this CPU works (instruction set, MMU, cache etc.) and what differences there are to a regular MIPS core.
Any info would help a lot with this project http://rtl8181.sf.net

I still have a pdf for the 4189 but I'm not sure about the NDA status so I can't give it away. I believe (could be wrong though) that MIPS Tech bought Lexra's assets, so they are probably the ones that have the docs.

We did, we must: and I don't know right off how to find the manual, or under what conditions I can give it out. But I'll make some enquiries and get back to you.
