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 -

For more complete information about compiler optimizations, see our Optimization Notice.

On IntelPXA25x processor,the answer is no.

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

Intel IPP
