Choosing DSP or FPGA for a Application?

[javad]

Dear Experts!
FPGA and DSP represent two very different approaches to signal processing – each good at different things. There are many high sampling rate applications that an FPGA does easily, while the DSP could not. Equally, there are many complex software problems that the FPGA cannot address.

These are some useful materials that can help you to select the best:

Evreryone have their own pros and cons...
for matehmatical operation appliation/ signal processing... u can choose DSP and for high freq operation obviously FPGA is better... and one more advantage of FPGA is its cheaper....and interfacing with ADC , DAC is also easier

when we require very high speed processing, we use FPGA.

when we require complex and low speed processing, we use DSP.

when we require high speed and complex processing, we use

DSP to do control and some processing, and use FPGA

for hardware accelerator.

best regards

FPGA has more advantage in special fields. for example ,in military filed, designer have to focus on EMC system . if you implement a task , maybe the clock is 50Mhz using FPGA, but 200Mhz in DSP. so 200Mhz could have trouble in EMC.
