What is the difference between FPGA and DSP please?

The difference between FPGA and DSP is as follows:

1. Hardware level is different.

In the hardware level, DSP is ASIC, as CPU GPU, suitable for mass production to reduce costs, the disadvantage is that the (hardware) design once determined, it is not easy to modify. FPGAs are more flexible and can be quickly designed and improved through hardware description languages, but are more costly and are traditionally used for ASIC prototype designs.

2, the software level is different.

At the software level, to write programs for DSPs and multi-core CPUs, to write programs for GPUs, there is not much difference, DSPs have a perfect C language compiler. The current high-end FPGAs are integrated with hard-core DSPs.

3. The programming languages are different.

FPGA mainly use HDL, including VHDl, Verilog, and mixed digital-analog description language Verilog-AMS, etc. DSP using C, assembly language programming.

4, ? Functional perspective is different.

FPGA is commonly used to implement digital circuit modules, basically all digital circuits, traditional digital function modules, as well as customer product-specific needs of the digital processing module.FPGA IO bridge a wide variety of different types of levels of FPGA support for IO standards and protocols are not the same, but these IO drive capability or voltage are programmable configuration.

The I/Os are all programmable.
