摘　　要：针对传统DSP+FPGA平台上EMIF总线速率低的问题,提出一种采用ZYNQ+FPGA硬件架构设计,使用Aurora高速串行总线互连通信。通过对Aurora总线进行编码,以软件虚拟化方式实现PS单元对FPGA端任意寄存器以及RAM或FIFO中的数据读写访问。相比传统EMIF总线,传输速率有大幅提升,设计具有很强的通用性和可移植性。To solve the problem of low speed of EMIF bus in traditional DSP+FPGA platform,a design using ZYNQ+FPGA hardware architecture is proposed,and Aurora high-speed serial bus is used to interconnect communication.By encoding the Aurora bus,the PS unit can read and write any register on the FPGA side and the data in RAM or FIFO in a software virtualization way.Compared with the traditional EMIF bus,the transmission rate is greatly improved,and the design has strong universality and portability.
