Hi Luke
ok so here's some links: https://github.com/enjoy-digital/litedram http://libre-riscv.org/shakti/m_class/DDR/ (hmm must update that) http://bugs.libre-riscv.org/show_bug.cgi?id=21 https://www.ohwr.org/projects/ddr3-sp6-core/wiki/wiki
Great! I will try to tinker them into SauMauPing! Thanks!
so there *is* an actual DDR3 controller *and* there is symbioticaeda who have an LPDDR3 PHY which they're happy to make libre given the right price.
That shouldn't be a problem as soon as we've got the PearlRiver done and everything works in the lab. We can also use the fab in Tai Po to serve mass orders in case there is a demand for their IP (in combination with other IPs of course) As soon as the process is ready they should join us in Mumble and discuss with us how much cash they expect from a potential mass-tapeout.
there's one other DDR3 controller that i know of, unfortunately it's GPL licensed.
As I mentioned before, the GPL isn't worth anything when used for licensing semiconductor IP because it stops covering the flow half the way. So worrying about "GPL or whatever" is pointless ;-) As soon as Cedric is done with the first revision of the LibreSilicon public license we will have something actually able to defend intellectual ownership rights over IPs. But right now he's on a business trip, trying not to get attacked by drop bears ;-)
Cheers David
