Is DSP faster than FPGA?

Recent FPGAs have included Multipliers especially for performing DSP tasks more efficiently. – For example, a 1M-gate Virtex-II™ device has 40 multipliers that can operate at more than 100MHz. In comparison with the DSP this gives 4000M multiplies per second.

What is the difference between DSP and FPGA?

DSP functions are commonly implemented on two types of programmable platforms: digital signal processors and field programmable gate arrays (FPGAs). Digital signal processors are a specialized form of microprocessor, while FPGAs are a form of highly configurable hardware.

Why use FPGA in signal processing?

FPGAs provide a reconfigurable solution that meets the requirement of diverse DSP applications. The use of legacy codes to perform functions empowers developers to design flow combined with hardware acceleration without extensive technical knowledge of hardware description language.

How DSP can interface with FPGA?

FPGAs provide a reconfigurable solution for implementing DSP applications as well as higher DSP throughput and raw data processing power than DSP processors. Since FPGAs can be reconfigured in hardware, FPGAs offer complete hardware customization while implementing various DSP applications.
