摘要
目前工业上还在大量选用不支持S/BPI加载方式的FPGA。针对XC4VLX25和XCF08P等能够使用JTAG仿真器进行加载,但是不支持S/BPI加载模式的器件,常用的在线升级方案有FPGA在线升级和PROM在线升级两种。基于JTAG协议阐述了FPGA在线加载的硬件设计、软件设计和升级方法,并通过实验平台进行了验证。
At present FPGA that does not support S/BPI loading way is still used in industrial field.There are two commonly used on-line loading scheme for XC4 VLX25 and XCF08 P can use JTAG emulator to load,but does not support S/BPI load model device,FPGA on-line loading and PROM on-line loading.The paper introduces the FPGA based on JTAG protocol online loading of hardware design,software design,on-line loading steps,and is verified by experiments.
