PowerUP (accelerator)

They had two different processors, a Motorola 68000 series (68k) and a PowerPC, working in parallel, sharing the complete address space of the Amiga computer system.

Due to a lack of resources, the PowerPC project at Amiga Technologies stalled and Phase5 had to launch accelerators without a PowerPC-native AmigaOS.

As a stopgap solution, a new PowerUP kernel was created allowing new PPC-native software run parallel with 68k Amiga OS.

[3] To complicate things even further, former Commodore International chief engineer Dave Haynie questioned Phase5's plans to develop PowerPC boards without Amiga Technologies: "Their approach on the software front is kind of a hack, and on the hardware front it's just too much like the old Commodore; at best, they'll wind up with interesting, non-standard, and overpriced machines that can't keep up with the rapid changes in the industry.

[5] Wolf Dietrich (managing director of phase5) earlier commented that "we found that Amiga Technologies offers us no sort of outlook or basis for developing into the future".

The accelerator board was famous for its high performance due to its 64 bit wide memory bus and PowerPC 604e processor.
