DSP on FPGA

Hi,

I am want to start implementing DSP ckts on FPGA. I am famlier with VHDL/Verilog, but have no idea how to go about in implementing filters, MACs etc...

Any suggestions about any sites or materials?

thanks in advance

Re: DSP on FPGA

I started using Altera’s DSP Builder with MATLAB / SIMULINK. It’s working pretty good for DSP.

Re: DSP on FPGA

whic kind of DSP function you would to implement?
Xilinx make the X4 to implement most DSP functions.

Re: DSP on FPGA

Hi jnanabindhu,
Implementation of FIR/MAC units on FPGAs is not a big problem as u know vhdl/verilog programming. i hope u r not familiar with the MAC/Filter architectures.
Study the architecture first.
There r many ways to implement these on FPGA,
1.HDL Coding
2.readymade IP's using CoreGenerator
3.BlockLevel Modelling using SystemGenerator under xilinx
U can expect a very good performance, when u r porting these MAC/FIR designs onto FPGA, as it has got many multipliers inside.
The new Virtex-4 architecture, has even got MAC engines inside, to improve the timing performance.

DSP on FPGA

implemention of filters (FIR/IIR) is quite easy(if they are not adaptive).just calculate your filter coeficients and then store it.then get your data in a register and do the canvolution.nd go on.but there is some details about convolution.do you see Openhaim. "Discrete time signal processing" chpter 8?

Re: DSP on FPGA

you can write code only, The sofware can do them for you.

software will select appropriate DSP for you.

Re: DSP on FPGA

i would recommend you the book



and search on google to find projects in which DSPs are implemented in FPGAs

Hi
there is a good book if you are planning to implement ur design in Viretex 4 devices

Re: DSP on FPGA

Hi


Me too verymuch interested in designing DSP on FPGA. But I don't know the procedure.

Can anybody please explain the step by step procedure of designing DSP on FPGA using MATLAB/SIMULINK with Altera/Xilinx DSP builder.



Thanks in advance

Hi

I know that the book for DSP on FPGAs is available at h**p://

But it requires more than 150 points to download. I don't have much points in my account.

Can anybody help me in this regard? Or can you please send the book to my mail ID umamahesh.korapala@gmail.com


Thanks & Regards,
Vishwa

Hello Vishwa

You don't need points to download this ebook. Just click on the "Free mirrors (no points)" link. The download speed is slower than the direct download link.

Re: DSP on FPGA

Hi vijaytanjore,

You can't covert matlab code in VHDL (or Verilog).
You have to builder the DSP project with the Altera DSP Builder Simulink Library.

I’ve stop using Altera’s DSP Builder and switched to Synplicity Syplify Pro & DSP tools.
Same problem, you have to use Synplicity’s Syplify DSP’s Library in Simulink to build a project.

Re: DSP on FPGA

Go to either Altera website or Xilinx and search for DSP keyword there...you will find enough in depth material.....hope it helps...

Re: DSP on FPGA

hi

I am having Altera DSP builder, i have no other options, bcaz we r having only UP3 Altera Cyclone Board. so i must use Altera DSP Builder

I need some materials to convert my matlab code into Simulink (model) code. can anybody help me to get the tutorial to convet matlab code into simulink model file

Do ur own DSP code just implement MAC, --> MF, FFT, FIR .....
