Cortex-A7 Processor DSP

Hello everyone.

I am new usage of Allwinner A20.

I read in Cortex-A7 specification, that it have DSP & SIMD extensions.

And if there are digital processing unit in processor, can i use it? Can i drop on it some code, as any other DSP? And if yes, will it work parallel with CPU?

Thanks,

Regards.
