The seven-segment digital display controller IP core design in the previous chapter is the AMBA APB bus interface, and our FBIO Wrapper provides the AMBA AXI bus interface, which cannot be directly connected together. An axi2apb Bridge is required for connection as follows
This experiment provides the corresponding AXI2ABP Bridge basic file axi2apb.v 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
