WarpOS was a multi-tasking kernel for the PowerPC architecture developed by Haage & Partner for the Amiga computer platform in the late 1990s and early 2000s. It ran on PowerUP accelerator boards developed by phase5 which contained both a Motorola 68000 family CPU and a PowerPC CPU with shared address space. WarpOS ran alongside the 68k-based AmigaOS, which could use the PowerPC as a coprocessor.
