说明：  “基于 ROM 的 LCD图片显示实验 ”中利用 FPGA 片上存储资源存储图片，并通过 LCD接口将图片显示到 LCD屏幕上。但是由于 FPGA 片上存储资源有限，只能存储分辨率较小的图片(In the experiment of LCD image display based on ROM, FPGA on-chip storage resources are used to store pictures, and the pictures are displayed on LCD screen through LCD interface. However, due to the limited on-chip memory resources of FPGA, it can only store images with smaller resolution)

there are exemple in the vhdl

本文研究了SMBus 规范，介绍了典型的基于片上系统（SoC）设计的知识产权核（IP）实现，采用自顶向下 (Top-down)的集成电路设计方法完成了设计，并架构了基于总线功能模型(BFM)的验证平台 完成功能仿真，顺利完成了逻辑综合和时序仿真。FPGA 验证和投片后测试均表明设计具有 良好的性能。(This paper studies the SMBus specification, based on the introduction of the typical system-on-chip (SoC) intellectual property core design (IP) implementation, using top-down (Top-down) of the integrated circuit design methods achieve a design and architecture based on the total Line functional model (BFM) achieve functional verification platform for simulation, successfully completed a logic synthesis and timing simulation. FPGA silicon validation and post-tests show that the design has good performance.)

说明：  this code works with spi and uart interfaces.
