Hi Everyone!!! I want to know about any FPGA board (xilinx make is preferred) with a DSP processor onboard which can be used to compute my soft computing algorithm. I googled but came up with no real solutions rather than some products from sundance multiprocessor technologies. I found no real solution from Xilinx. Problem Is there any other approach for the mentioned problem. I thought a dedicated DSP will be better to use for the heavy computations. I am a newbie in Hardware implementation. Please help.
Thnx.....
 

Well your description is fairly vague and a bit confusing... but i'll take a stab at it!

TI is partnered with Xilinx and offers DSP+FPGA solutions. I'd start there. I've done interfacing between the devices using TI McBSP, but that won't be easy if you don't know much hardware design. See also, XAPP753. See also:
Avnet TI OMAP/Spartan-6 FPGA Co-Processing Kit

I thought a dedicated DSP will be better to use for the heavy computations

Actually, to the contrary! Dedicated HW will outperform software DSP algorithms usually. But your choice of HW and processor will depend on your target application.
 

Hey Guitarguy!!!
Thank you very much for your reply. I actually would like to have your suggestion on this approach. I am basically a matlab, simulink and labview programmer till now. Its little tough for me to be thrown into the hardware design. I have any algorithm which is to implement adaptive fuzzification. It has 8 inputs with 7 membership functions. Then there is a controller part based on fuzzy logic. Then there is a defuzzifier which which gives two output. I have a computational requirement of 100 cycles per second. Input signal of -5 to +5 v and frequency 100kHz. What can be a possible approach for this?

Thnx again
 

Hey!
No problem. Well I wish I could help, but I really don't know any fuzzy control theory beyond wikipedia headlines haha! If I understand the algorithm you're using, I may be able to suggest something. Do you have any specs or block diagrams or something? Simulink model?. I'm assuming you'll be using an A/D for the 'input signal' ? Also, I am not sure what the meaning of your 'computational requirement' is.

In general, if you like simulink, i'd look into SysGen :) Though you will want to know some HW design principles to make implementation/design decisions when configuring the blocks.
