WarpUP/WarpOS/powerpc.library is PowerPC kernel/subsystem for AmigaOS, made by Haage&Partner.

It has basically the same function as original PowerUP/ppc.library from Phase5: running Amiga programs on PowerPC CPU.

There is no third kernel for AmigaOS3. But there is more PPC kernels for classic Amiga - MorphOS's Quark and OS4's ExecSG.

WarpOS is able to emulate PowerUP. MorphOS is able to emulate them both.
