"Spiip串行外围设备接口设计与优化研究"

al Peripheral Interface) is a high-speed, full-duplex, synchronous communication bus that only requires four wires on the chip's pins. It is commonly used for connecting serial peripherals. SPI flash is primarily used for storing code or other non-volatile storage applications. The purpose of this design is to develop an SPI flash controller, which acts as a bridge between the upper-level driver and the flash device. The controller receives parallel data and control signals from the upper level, processes them, and then sends them to the flash device in a serial manner to perform various operations such as read and write. The design is implemented using the Verilog HDL language and developed in the Vi editor. The design is then compiled, simulated, and debugged using EDA tools. Finally, the results are verified on an FPGA. After completing all the mentioned tasks, the design is analyzed and summarized in terms of functionality, area optimization, and cost reduction. This analysis provides valuable experience gained during this graduation project. Keywords: Flash memory, Verilog HDL, serial, parallel, FPGA.
