OpenMAX acceleration

Wed Feb 27, 2013 3:28 pm

How OpenMAX is able to do some acceleration if there is no Neon SIMD support in pi?
By the way, I am not sure what this VPU support is that is mentioned in this post:

If there is truly a VPU available, how can I make use of it with OpenMAX?
And, even though OpenMAX IL has codec libraries, but OpenMAX DL has accelerated Image Codecs ( Can PI make use of OpenMAX DL library?
How would it accelerate it, if there is no SIMD support?

For example, I know that OpenCV cannot be much of a help, since there is no SIMD support in pi?
But if I want to use a jpeg decoder (no encoding), will I still get faster performance with OpenMAX?
How would I make sure that I am using the most out of my GPU with OpenMAX for decoding images?
