Research on FPGA-based Implementation of FIR Digital Filters

In this document, we will discuss the following topics: 1. Research on FPGA implementation of FIR digital filters. By programming with VHDL language, we can implement efficient digital filtering functionality through optimized filter coefficient quantization, parallel processing architecture, and pipelined design approaches to achieve high-speed signal processing. 2. Design of multi-functional microcontroller download development hardware and software. We will utilize VB or VC++ and C programming languages to complete this project, implementing firmware programming protocols, serial communication interfaces, and download verification algorithms, including the download board software component with error-checking mechanisms. 3. Design of a mini media player. We will use Visual Basic 6.0 to design a powerful mini player that incorporates multimedia decoding libraries, playlist management systems, and graphical user interface components. The player supports multiple audio and video formats playback, along with image browsing capabilities and format conversion features. 4. Introduction to compact capacitance and inductance testing instrument. We will discuss in detail how to design and manufacture a small-scale capacitance and inductance testing device. This instrument employs oscillation frequency measurement methods, impedance analysis algorithms, and calibration techniques to accurately measure and test the characteristics of small capacitors and inductors with precision measurement circuits.
