Where to start on a PS2 to PSP Port.

[psptig]

Hi,

I'm looking at porting some old PS2 stuff to the PSP, the main process was to dump the the data to Vu1 for rendering
while the other Vu and main CPU dealt with the rest of the stuff.

I've read that the PSP has the Vu, can I just use all my Vu assembler as just like the PS2?. Are DMA chains created simlar to the PS2?

Have I got it all wrong and the psp is more like just programming the GE direct on the PS2 as the example sdk mostly
does?

Any pointers would be great

Thanks

There is no VU on the PSP, instead there is a VFPU which is a coprocessor (in the same way as VU0, but a completely different architecture).

Check out http://wiki.ps2dev.org/ for information on the PSP's architecture. Check out the samples in PSPSDK and peruse these forums to become familiar with PSP programming.
