GSP与PCI交互的FPGA接口设计与实现

Design and research of FPGA interface between GSP and PCI

提出以TMS34020图形芯片为核心的图形系统处理器(GSP)图像处理系统,应用Altera公司用户可编程逻辑阵列(FPGA)EP1C6Q240I7完成接口设计。在FPGA上,应用硬件描述语言AHDL设计I/O读写、存储器读写等逻辑。在逻辑设计过程中,借助QuartusⅡ平台进行硬件逻辑的前后仿真,并下载到FPGA中,实现接口电路的功能。

Suggested a system of GSP,which was used chip TMS34020 as key,and apply the embedded programmable chip of Altera company i.e.EP1C6Q240I7,to implement the design of the interface.On the basis of FPGA,designed reading and writing transport of I/O and memory by using the language of AHDL,in the process of design,simulation is achieved by Quartus Ⅱ,download in the FPGA,finishing the function of the interface.
