前面章节的七段数码管显示控制器IP核设计是AMBA  APB总线接口,而我们FBIO Wrapper是AMBA  AXI总线接口, 不能直接连接在一起,需要一个AXI2ABP 的Bridge进行连接,如下

...

本实验提供了相应的AXI2ABP Bridge基础文件axi2apb_64.v,如下

...

The seven-segment digital display controller IP core design in the previous chapter is the AMBA APB bus interface, We choose apb_ bus_ m32_bridge module from Bus Bridge series ,so the APB master bus interface provided by the bus bride module is used to connect our IP as follows

...

This experiment provides the corresponding Bus Bridge module file: apb_bus_m32_bridge.v and apb_bus_m32_bridge.edf

The corresponding connection between the design case and the hardware platform (SP7021 motherboard and FPGA daughter board) pin is shown in the following table: 1: U20B on the motherboard is connected to J2 of the FPGA daughter board (Pin pin corresponding, such as 1-51 ...), providing the data transmission channel between the Plus1 main chip on the motherboard and the FPGA
