Generality and efficiency are complex, multifaceted concepts. It's easy to focus on one particular weakness of a given approach. But in the end what matters is the actual performance, efficiency and flexibility that a chip delivers for a specific application.

It is a tough call I believe, since applications where power is the focus will do better if DSP chips are used and when performance is the issue, then I guess FPGA can scale up much better due to the inherent presence of parallelism.
What do you think?

True, FPGAs deliver more flexibility than DSPs in terms of processing, or say than ASICs in terms of reconfigurability. Apart from this, FPGAs also deliver another value-add: they are inherently parallel such that the "logic blocks" can be programmed, which then makes them valuable in next-gen applications. To shed more light on this, see story: NI: Path leads to parallel. Let me know what you think.

I think in terms of exploiting parallel-running, multicore systems, FPGAs have an edge over DSPs. Though for apps running signal processing, DSPs will offer more efficiency in terms of resource use. I guess, the designer's call depends on the design being implemented. What do you think Soda?

No doubt, FPGA is much much more powerful than DSP, whatever DSP can do can also be implemented with FPGA, and FPGA does much faster. The advantage of DSP over FPGA is power efficiency, but it is not so big because the power consumption of FPGA is becoming lower and lower.
I think that the future trend will be FPGA instead of DSP because alogrithms are becoming more complicated but speed requirement is increasing amazingly.

To say that "FPGAs will replace DSPs" is a very straightforward foresight but nonetheless possible, with the rate inno......
