Signal Processing with MALI 400 MP

Note: This was originally posted on 16th April 2012 at http://forums.arm.com

Hi, I would like to offload the main CPU from some heavy brute-force signal processing and use the GPU for that.

For example, multiplying an array of floats by a scalar, or doing multiply-accumulates like a += coef[i] * data[i];

I don't know if this is possible with the MALI 400, if I have to use Open GL ES or the shader or ?
That would be great if I could develop and test all my GPU algorithms on the PC instead of doing it on the device.

I know more and more people are talking about this (with some NVIDIA GPU).
Any information is welcome, because I don't know where to start !
