Broadway (Wii GPU) is PowerPC .  The CPU in the Wii U is Power 7.

Hollywood (Wii GPU) was originally based on the ARTx designed GC Flipper GPU which utilized a TEV fixed function pipeline rather than AMD's unified shader architecture.

 

Because both the GPU and CPU are very different architecures, it requires them to have much of the Wii hardware built in to emulate the games and operate all the Wii peripherals with flawless operability.

1. power7 is ppc according to wikipedia. the isa is compatible.vhttp://en.wikipedia.org/wiki/Gekko_(microprocessor) look at the right boxes.

2. gpu could be more tricky, yes. but as details from wiiU by now are missing.

3. if the hardware is built-in then you can't really speak of emulation.

1. No, it's not.   The box on the right has seperate sections for PowerPC and Power7.  Don't confuse PowerPC and Power7 with POWER architecture.

so you say the power isa of power7 is not backwards compatible? aix from ibm has to be rewritten for every new power-generation? somehow i doubt that. intel changed a lot with their latest generation cpus, but you still can write code for 386 and execute it.

Yes, there is a lot of backwards compatibility with each new instruction set but the differnces between a PowerPC 750CE and a Power7 CPU means you can't just drop code from the former on the latter and expect it to run.
