<br>
</span>you don't. ARM is a registered trademark, and copying what they're<br>
doing is asking for trouble.<br>
<br>
instead you take one of the "open gpus" or parts of them and use that.<br>
there's several i've been tracking: MIAOW, Nyuzi, the ORSOC graphics<br>
accelerator - there's surprisingly quite a lot out there.<br>
<span class=""><br>

<br>
</span> it would be on the same silicon, on the same memory bus as the RISC-V<br>
64-bit core. anything else is too power-hungry.<br>
<span class=""><br>
> Would you put it additionally on a bord and not use the gpu located on the processor socket?<br>
<br>
</span> no.<br>
<span class=""><br>
> If you reverse engineer the latest mali gpu, what you hold against it is, that when next version of an arm socket is for sale it will have a new mali gpu and require a new reverse engineering?<br>
<br>
</span> correct. so whatever you get it's guaranteed to be "old". this is<br>
the sad fact of reverse-engineering: all that effort, with *no<br>
guarantee of success*.... just to get something that's years<br>
out-of-date.<br>

<br>
</span>no. ARM has acted so unethically in slandering luc verhaegen and<br>
blackmailing companies that pay him that i am not interested in<br>
supporting their business any more than is absolutely necessary.<br>
<span class=""><br>

<br>
</span> yes. a _lot_. however amazingly people are actually doing just<br>
that... even on risc-v where there isn't yet even any actual hardware.<br>
<span class=""><br>
> It is unfortunate people are not able to coordinate such that we can get source code hardware.<br>
<br>
</span> it's still quite a young area of focus.<br>
