Re: [Libre-silicon-devel] SoC for GPU project

Hi

a much faster option is xSPI (HyperRAM). it's less pins (12), runs at 150mhz for the non-DDR variant, and can do up to 150 mbyte/sec. if you want 300mbyte/sec, put in two HyperRAM interfaces.

edmund's team has a libre-licensed HyperRAM implementation done already.

i think it was micron who have 64 mbyte HyperRAM ICs commercially available.

Fantastic! I'll immediately look at it!

now... if OpenRAM were to implement a libre-licensed HyperRAM chip instead of SRAM that would be REALLY interesting.

Well. We directly talk and cooperate with the OpenRAM folks, so we can certainly arrange that :-)

Cheers David
