NettetSIMD intrinsics functions take primitive arguments that correspondtolow-levelC/C++primitivetypes.Theprimitive types in the JVM exhibit a ixed width, and therefore a direct mapping can be established with C/C++primitives. Some intrinsics however, require the use of unsigned types that are not supported natively in the JVM: NettetOn Intel mainstream CPUs (not Atom/Silvermont) these are somewhat faster than doing it manually with multiple instructions. But on AMD (including Ryzen), dpps is significantly …
