Ok here is the new home..... I'm still working on the page: http://www.alterawiki.com/wiki/modular_sgdma
The old link is being killed off so if you use this IP please switch over to using the wiki version since it has an additional bug fix.
I'll list this on the wiki page but the new version on the wiki is intended to be provided as is and only bug fixes should be made to it. If you want to contribute to a derivative mSGDMA make a new wiki page to host the derivative and link to it from the main page. In other words the main page is treated as the basis and the derivative pages are the one-off versions with extra features removed/added that others may not want.
