Hardware Neural Network

Hi all,

I'm a university student, and I'm realizing a research on artificial
neural networks. The aim of my research is the feasibility of putting
an artificial neural network on a microcontroller or a DSP. Because of
the sigmoid function, I think that would be necessary a 32-bit
microcontroller (or DSP) for floating point operations. I was
searching online but I only had found exhaustive informations on
software realization of ANN's, but it's not what I was searching for.
Does someone have any hint or any previous experience on the hardware
realization of an ANN?
I think the better solution is the DSP, due to its power on floating
points operation, is it right?

Here are some details of the network:

5 or 6 inputs
about 10 neurons in the hidden layer
2 outputs

Thanks in advance,

Daniele.
