| Abstract: | Using FPGA as coprocessor to DSP can take the advantage of DSP in data processing, promote performance of the system, and strengthen the handling and controlling capacity of the whole system, which gives a low costand fast solution to design scheme in many complicted application situations. This paper expounds the process of realizing DSP function by FPGA digital logic in several aspocts as the realization of data space extension, responding to multi-interrupting sources by single interrupting signal input, timing sequence conversion. This method bears teaching reference value and has the significance of guiding engineering. |
