Wait a sec! Last year you said:

Best knowledge is, that new intel and amd processors cannot be reverse engineered. What in regard of the latest mali gpus? If you have the money, they can be reverse engineered?
yes. about $150k would do it. but the question is, really: what would happen if you did? and, what else could you do with the same money?
well, with the same money it would be possible to make our own libre processor, with enough extensions to be able to do 3D graphics *without* paying anyone a cent. any company tries to claim patent royalties, all that happens is a search is made on their "claims", for anything similar that has prior art.
if it's another company, guess what? we notify that other company and watch the fireworks...

1M - 150k = 750K!!! Therefore you're tripling your price estimate on us!
it depends on what you take into account. if someone else pays the NREs to the foundry, i.e. a university agrees to collaborate and is offered access to a foundry for either free or at reduced rates, $250k-$500k comes off that amount, straight away.
My statement was based on: 1M - (3 x 150K == 450K [for the HDL]) = 550K for the silicon, and that's huge! What is the cost here? Silicon as an element is inexpensive and even 32nm foundries should have their HW paid for by now. It's been what? 8 years since 32nm and the half node, 28nm started? And the big buyers (AMD, Intel, Nvidia) were on it for 3+ years.
It's not like an OSH project can purchase a license for closed source HW something-or-another libraries, which I've read as being the main expense from anandtech (No, I'm not in the field).
if only wanting to reach a target of say producing the design files (HDL), that's a different target entirely as well, and if someone else can take over at that point (and make the actual money selling product), then that's one way to ensure that the goal's reached [but not guarantee financial benefit from it].
I assumed at the time, you were talking HDL and with an FPGA for hardware backing with basic OpenGL, OpenCL, and 2D driver. No video encode/decode HW or Vulkan driver. Not mass produced, just a few prototypes. At about the same speed as a good Intel GPU, say a high end HD630 series. If you have a more concrete or different idea I'd be glad to hear it.
so it was a throwaway comment written in about 30 seconds with no strict analysis done.
Really? You sounded so serious! Contrary to popular belief, sound does travel across the Internet, it's just that no body has managed to tie the Internet into the speakers yet. ;-)
last time i collaborated with an associate to come up with a proper figure it was around USD $5m (for a client) and it took us around five days to put that together. however that particular deal excluded certain resources and had specific requirements.
:( I was aiming for 2M minimum. And that is BIG to me.
Seriously, when I get BIG money (which will be a while),
cool
Let me be frank, luke, I am under no delusions. No lottery. No gambling. No get rich quick schemes. But it will take time, as in ~5 years. Therefore, be excited about the OSH, not the money which may or may never be there.
I don't always agree with you, but what you write I do pay attention to. And I have a terrible tendency of believing you. :) I had assumed that some company would opensource or support the OSS Mali drivers, eventually. Google has android running off of Mali, Samsung and LG have Smart TVs running off of Mali, the list goes on... But when you wrote about creating an OSH GPU yourself I realized that is spite of every Mali customer, Google et. al. would not support opensourcing anything if they could help it. Chromium's binary blob problems are even further proof. This became painfully clear when RISC-V came out. I expected *at least* the cache to be OSH... :CRY:
I decided that if I could, it was up to me to pull in the funds for OSH, and "I think I can"(TM).
I'm planning on calling you on this one
excellent. well, when that happens, let's talk (on or off list), you let me know what you can raise and i'll put the time in - which will be several days not a few moments - to work out what can be done, and what side-deals will be needed, if necessary.
l.
I will tell you, but keep in mind that there are other OSH products to be developed that I have my eyes on.
Finally, I'm uncertain that I want to know, but what is a "side deal"?
Thanks!
