I can't tell who did this latest GPU and without spending a bunch of time digging through code, I can't tell what its features are. Is there an actual GPU in there, or is it just memory and video controllers? What kind of rendering can it do? The blog seems to imply that 2D isn't even working. We could do a dumb framebuffer in 2007. There were some people from Silicon Spectrum (that bought the IP from Number Nine) who were looking at putting their design into the open source, and I think they did a kickstarter. But I can't easily find any info on the identity of the people who are doing this one.
Sometimes I worry that the OGP may have inadvertently caused some trouble, because every time someone else tries to do the open source GPU thing, the response from the community is "been there, didn't do it." If we had a synthesizable design in Verilog that COULD perform at cutting edge performance, if only we could put it in a cutting edge chip technology, then that might help. I have bits and pieces, but I haven't had time to work on it. Currently, we've got a paper written that we're submitting for publication. It involves an open source GPU developed by another member of OGML. And we're looking at doing some other research in that area. Once we have a few papers, we can apply for grants. We did try to get one masters student to work on OGA2's ALU, but that didn't work out very well. If we can get funding, then we can justify spending a lot more time on it ourselves, along with funding students. There's lots of room for research on GPUs, and one or more completed synthesizable GPUs will emerge as byproducts. Currently, we have a graduate student collecting the latest research on GPU memory systems (virtual memory, exceptions, page faults, TLBs, etc.).
