Hi,

Beside Xilinx, you can also consider Altera DSPBuilder Tools and you can get started with their Cyclone DSP Kit at USD990. The kit comes with Altera DSPBuilder which is Xilinx's System Generator equivalent. However, if you just want to write in VHDL and on a tight budget, consider getting a DE1 board for USD150.

I too don't work for Altera but are using their tools to teach. We have both Xilinx and Altera tools but students tend to find Altera's interface more user friendly. However, I would say they do the same job, it is just a personal preference.

There is also a support forum for Altera at http://www.alteraforum.com.

Warning: nothing worth doing is ever easy!

Do you already have a background in DSP? If not, then
you really have your work cut out for you. I spent
years trying to teach myself on the job and eventually
went back to school to earn a masters degree in
electrical engineering with an emphasis on signal
processing. Good luck indeed!

Assuming you already have a background in DSP, your
challenge is more manageable. You'll need to learn a
hardware definition language such as Verilog or VHDL
or perhaps one of the newer languages like SystemC or
Handel-C. There are also graphical programming
environments but the tools tend to be expensive. For
instance there are tools that will convert Simulink
models into FPGA implementations.

One freely available development environment that I've
worked with is Xilinx ISE WebPack.
(http://www.xilinx.com/ise/logic_design_prod/webpack.htm)
The WebPack version limits the size of the designs
that you can develop but otherwise has all the
features of the full-up version.

As for books, I haven't run across any that
specifically address implementing DSP systems on
FPGAs. However, Xilinx publishes a good magazine on
the topic:
http://www.xilinx.com/publications/magazines/dsp_02/index.htm
. No, I don't work for Xilinx, I'm just a satisfied
customer :)

Can you introduces about books and best tools :D
Have a easy way to study about this subject ?
Goodluck :)
