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

They'll have papers. Try, in order, Xilinx, Altera, Cypris, Actel, QuickLogic, Atmel and the rest. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

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. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

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. -- glen

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

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. -- Al Clark Danville Signal Processing, Inc. -------------------------------------------------------------------- Purveyors of Fine DSP Hardware and other Cool Stuff Available at http://www.danvillesignal.com

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. -- Dave Tweed
