Hello everyone who are related to the DSP field. I went thr' the following site
http://www.andraka.com/
The kind of work which they have done is really good & they are saying that a FPGA can replace a dsp processor & it will in the future.
I feel this is going to be impossible coz to implement all the various processes at gate level is going to be very diffcult.
 

Hi friend,
Kindly note that the gate level design of FPGA is no more.
The complexity is already high that it has lead to many high level designs with modular approach. If you could develop a whole system on a single chip (SOC)
it is no far that VLSI will replace the DSP processors.

Actually FPGA's with embedded DSP blocks and huge amount of memory are already available in the market and it will surely replace the DSP processors in near future
 

Well the answer to this question is pretty tricky.

DSP processors are more or less used in the prototying phase and many cases end user system, but this is changing as the technology is getting mature and so is the developed software and algorithms.

Once the implementation is found to be pretty stable the sensible option would be to make a SoC ( system on chip ) solution so that it can be sold as on off the shelf solution for a quick time to market.

But all this generally doesnt mean end of life for DSP, but yes less and less work for guys having knowledge of dsp processors rather than signal processing
 

Oh its almost year now...
what is current status of this problem?
 

Hello all,
personally I don't think that in the future FPGAs will replace DSPs. Modern DSP processors are not designed to do only MAC operations: the border line between GPP/MCU and DSP is not so clear as in the past (just consider TI C6000 family, the DaVinci and OMAP series or Analog BlackFin processors). For few dollars you
can get a very powerful machine for what strictly concern signal processing operations (MAC) and at the same time capable to perform system control and other operations normally allocated to GPP/MCU. Think also that today use of assembly for DSP is limited to critical routines, where the maximum performances are required while the majority of the sw running on this platforms is written in C, known by almost all engineers and widely used for systems modeling and simulation before implementation on a specific platform, while this is not true for FPGA and VHDL.
The real question is not if or when the FPGA will replace DSP or vice versa: is like talking about angels gender.
The designer shall have to evaluate all possible alternatives and make his choices according to the following criteria:
- performances
- costs
- time to market
that's all.

I don't know what do you mean the "VLSI"?
Actually the DSP processor is implemented by VLSI.
 

hey...

VLSI is the way the processors are implemented...
the algos of DSP are implemented IN VLSI n this is what we call the DSP processors....

if i am wrong can u let me know?
 

These are two different fields which are getting closer due to technological advances and they keep to grow simultaneously.
one can influence the others performancebut never does it replace(ofcourse replace is not the appropriate word)
