通过Cypress的EZ-USB FX3的SPI接口对Xilinx FPGA进行配置(AN84868 shows you how to configure a Xilinx FPGA over a slave serial interface using FX3 which is the next-generation USB 3.0 peripheral controller.)

Verilog implementation of an SPI slave interface. Intially targetted for Atlys devkit (Xilinx Spartan-6) controlled by TotalPhase Cheetah USB/SPI adapter

一般而言，Xilinx Microblaze会被用来在系统中做一些控制类和简单接口的辅助性工作，比如运行IIC、SPI、UART之类的低速接口驱动，对FPGA逻辑功能模块初始化配置及做些辅助计算等等。类程序的代码量普遍不大，常常在十几KB到几时KB之间，因此对存储的需求通常也不是太高，使用FPGA内部RAM资源便已经够用(Generally speaking, Xilinx Microblaze will be used to do some auxiliary work of control
