16-bit vector ops on PXA25x

16-bit vector ops on PXA25x

I haven't been able to determine whether 16-bit vector instructionsin IPP forPXA25x are executed two-at-a-time, or whether the upper 16 bits of the ARM ALU are unused for all 16-bitoperations?

This will affect our decision of whether to use the PXA25x or a cheaper 16-bit processor.

Thanks -

On IntelPXA25x processor,the answer is no.

But for the latest Intel PCA for Wireless MMX Technology process, the answer is Yes.

Thanks,
