For a topical update on this, check Xilinx website news on their
purchase of AccelChip.
As you can see, these newest tool flows somewhat side-step the need for
DSP Cores, per-se.

I thought the tool flows supported this now, but via the DSP blocks ?
-ie rather than a separate 'core', you compile what you want, into
as many DSP Cells as you need ?
A Soft-DSP will never be as fast as a dedicated device, the key
in FPGA is to spawn DSP in parallel and in HW.
Check with Altera, Lattice, Xilinx...

Why?
If you have DSP function to perform, do it in hardware, it is much
faster and consumes less power. Otherwise, use a dedicated DSP
microprocessor...again, far faster and consumes less power, and more
supportable.

I have seen one or two, but it was a long time ago. People doing DSP on
FPGAs prefer implementing the function directly in hardware as it's
much faster and more cost-effective.

Hi folks,
are there any DSP soft processor cores for fpgas available. I have done
a search and only found 32 bit RISCs but no DSP processor cores.
Thanks in advance
