I remember a few year back i was a member of the OGP group.
The group was able to do a development platform for the hardware. Also a demo code was made to support VGA and a first iteration of a fix GPU was made.
At the end we were a few working on a spec for the Programmable GPU, before starting to code it to test.
What was released was another project in collaboration with the leader of the OGP. For those who don't get what the news mean :
-It's a programmable GPU
-It can be turned into hardware
-People can thinker with it and improve it
-It's a working base for hardware test in FPGA and software simulation
-The available and open code for a GPU.
-It's not commercial, it's academic
-Graduate and undergraduate student across the globe now have access to it for student project and thesis work
What it's not is:
-A graphic card you can buy
It is a pretty great news for those into the open hardware community. Albeit a latter one than most wished. But it is a game changing moment.
