minus-squarepizzaboilinkfedilinkEnglish23•5 months agoIs there a good resource out there for wrapping my head around RISC-V? Last time I read a wiki my head hurt haha. Seems cool, though.
minus-square@[email protected]linkfedilink20•edit-25 months agoIn principle it’s just "slimmer ARM!. RISC-V is also extremely dedicated to using memory mapped IO rather than older style IO x86_64 supports. Think lots of registers, a fun zero register that is always zero, and memory mapped IO.
minus-squarecaseyweedermanlinkfedilink3•5 months agoARM is also reduced-instruction set but I don’t know how they differ. Is the instruction set somehow more reduced?
minus-square@[email protected]linkfedilink3•5 months agoAren’t they more like a hybrid instruction set and architecture?
minus-square@[email protected]linkfedilink5•5 months agoI for one think we need a register for each unsigned integer, why is zero so special? :P Or if we can’t get that, at least every power of 2 and power of 2 minus 1. Maybe I can submit a proposal for risc-VI 🤣
minus-square@[email protected]linkfedilinkEnglish5•5 months agoI think a register for each of the primes should be enough.

RISC-V
I want open-source hardware
