Hi!
	I'm looking for links about implementing DSP algorithms in FPGAs. Could 
someone help me ('couse Google can't help me well)?

Thanks!

There may be some papers at http://andraka.com/.

All of the FPGA companies are falling over themselves to sell their DSP 
capabilities, they all have some hardware features that make building a 
MAC operation fast (Xilinx and, AFAIK, Altera both offer hardware 
multipliers).

They'll have papers.  Try, in order, Xilinx, Altera, Cypris, Actel, 
QuickLogic, Atmel and the rest.

We will soon be releasing a new set of dsp boards that feature both an 
Altera Cyclone FPGA and an Analog Devices SHARC DSP. You can use the FPGA 
for additional signal processing or general purpose I/O

Check out our web site in the next few weeks or add yourself to our mail 
list and you will receive an announcement if you are interested.

Al, how do you plan on interfacing the DSP to the FPGA in a general manner?

I don't know how Al is going to do it, but when I was last on this sort 
of project we used a DSP with an external bus and memory-mapped the 
FPGA.  It worked quite well.

Then they all came out with 16-bit DSP's that'd do 150MHz and we tossed 
the FPGA and just do it all in one very busy DSP chip.

You need to be more specific.  An FPGA is just a bunch of logic,
so you need to know what logic will implement the algorithm.  It 
is often very different than the way it would be done in 
software.  I recommend systolic arrays, but it depends very much 
on the problem you are trying to solve.

..and there's all us friendly chaps (including Mr. Andraka) over on
comp.arch.fpga too.

We started with an Analog Devices ADSP-2126x or ADSP-2136x DSP. This 
gives us three main interfaces:

DAI - This interface is kind of a crossbar switch in front of high speed 
serial ports (SPORTs) and other I/O.

SPI - Convenient as the for control bus, we use it all over 

Parallel Port - A muxed data bus on these DSPs with lines AD15-AD0, ALE 
RD & WR. We mostly use it for SDRAM expansion 

The DSP and FPGA connect via the Parallel Port, the complete DAI, and the 
SPI port. They are kind of like siamese twins. The DSP is the master and 
is responsible for configuring the FPGA. Everything is stored in flash.

Since the FPGA and DSP can both see the outside world and talk to each 
other, there are lots of possibilities. We have a small module that you 
can use as a building block (dspblok 21261, 21262 & 21364) module and 
dspstak boards that include USB & RS-232. You just add an I/O card and 
start programming.

We will have info on our web site in the next few weeks.

I'm working on an embedded project based on the TigerSharc (TS201).
These chips emphasize CPU performance and on-chip memory at the
expense of on-chip I/O, which is limited to the four link ports and
the 64-bit local bus. I'm hanging a (Xilinx) FPGA onto one of the
link ports to provide all of the application-specific I/O (primarily
async and sync serial ports of various types). The link port carries
a fairly general-purpose message protocol that allows data to be
directed to or received from any of the FPGA ports.
