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 class and simple interface in the system, such as running low-speed interface driver such as IIC, SPI and UART, initializing configuration of FPGA logic function module and doing auxiliary calculation. The amount of code of class programs is generally not large, often between KB and KB, so the demand for storage is usually not too high. The use of FPGA internal RAM resources is enough.)
