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.
Hello,
Martin Weidmann. say that A20 does NOT include a discrete DSP BUT has several media instructions.
I am not sure whether a compiler can generate such instructions.
You can use them by an assembler.
