Abstract
SPI now is one of the very fashioned series synchronous interface.According to the performance character of SPI bus,this paper takes MG2455-F48 as the host and FPGA as the slave in the hardware section.VHDL language is used to design the slave of SPI bus to realize the communication between the host and slave.At last.this paper verified the correctness of the design through the simulation tool ModelSim PLUS 6.2b.This modular design is simple and flexible.it can be widely applied to various communication systems.
