Do FPGA provide special feature for DSP application development?
Yes. Today several FPGA manufactures provides different types of FPGA which come with some special hardware which is suitable for DSP application development. For Example, Most of the FPGAs which are aimed for DSP application development come with MAC unit (Multiply and Accumulate Unit) so that the DSP application can run faster on FPGA. For more information on this particular aspect lot of literature can be browse on internet from several FPGA vender websites.
