    RISC-V is inherently a customizable ISA though, whereas ARM implementations are very specific about what they require to be called an "ARM processor". This wouldnt change from this…

    no. they're isolated for a reason, with the RISC-V processor being used as the controller to manage the behavior of the other parts of the chip. beyond just licensing ARM is expens…

    you do realize that Nvidia is a major backer of RISC-V and already uses it on GPU's Turing and newer?

    You also inherit an entire chain of trust over code you yourself didn't write nor did anyone actually validate. The issue with leftpad.js wasn't that it was stupid, it was that it …

    yeah... I don't know what numbers you're looking at but that's not true in the general case. and this isn't firmware, it's microcode. firmware is already on the chip. microcode is …

    you talk about enabling signed firmware like it was done for a proprietary reason and not a massive security one. take a look at the fake Pascal gpu's on ebay where people are flas…
