Design and hardware implementation of FIR digital filter

This article is about the hardware application of one of the basic filters (FIR filter) often used in digital signal processing. First, it introduces the development process of FIR digital filter and the development of FIR digital filter today, and then introduces FIR digital filter. The part combined with hardware, including the research on the hardware implementation technology of the programmable digital filter based on the emictor, the combination with the memistor and the combination with the programmable logic device FPGA is the second most typical research on the combination of digital signal processing technology and hardware in recent years, which respectively describes its main realisation. The combination of FIR digital filter and different hardware methods also has different advantages, but in general, compared with its separate development, the combination of hardware and it has more advantages.
