Very nice, I'll have to see if I can get this running on my Zedboard.

Or parallella.

Terminology is getting confusing. I thought gpgpu was a term of programming a graphics card to do gp things.

wmf2• 12 years ago

It's basically a GPU without the graphics-specific hardware.

I wonder if this is competitive with the Intel graphics on their cpus. Intel gpus are not exactly stellar.

It doesn't seem he has tried taping this out as an ASIC yet. Unless you fab the circuit in the same process as Intel uses (which you won't be able to do unless you work for Intel), any performance comparisons would be pretty meaningless.

One just needs a wafer scale FPGA.

cwzwarich• 12 years ago

Nothing running on an FPGA that implements a GPU architecture / instruction set will be competitive with any recent Intel graphics.

Paraphrasing Winston Churchill, "However beautiful the theory, you should occasionally look at the evidence."

CamperBob2• 12 years ago

Why not?

Where is this GPGPU used (or going to be used)?

le_meta• 12 years ago

In your imagination, where several layers of unneeded abstraction actually accelerate processing.

It's a hobby project, mostly to learn more about hardware and computer architecture. I've done a few performance investigations and documented them here: http://latchup.blogspot.com/

You should do some more posts about the Lisp and Many Core cpus you wrote.

This is not GPGPU, this is: http://en.wikipedia.org/wiki/General-purpose_computing_on_gr...

I agree the term seems a bit strange, but people seem to know what it means (Larrabee was often referred to as a GPGPU http://en.wikipedia.org/wiki/Larrabee_(microarchitecture) ). I couldn't think of another term to call it. People also object sometimes to the term "IP Core" on similar grounds, but everyone knows what it means.

wow, this is nothing short of incredible.

i wonder if an OpenCL stack can be made..
