| 中文摘要: |
| 传统的ISP技术有使用JTAG技术或者单片机内部驻留BOOT程序的方法,这些方法或者成本较高,或者无法适应大规模应用的需求。介绍了一种使用CPLD辅助实现单片机下载更新应用程序的方法,应用该方法,可以使用大容量的片外FLASH做为程序存储器,在较低的成本下实现大规模应用中的程序在线更新。根据实际需要,我们可以设计符合自己需求的bootload-er程序。 |
| 英文摘要: |
| The traditional ISP technology uses JTAG technology or the methods of MCU internal resident BOOT program.The costs of these methods are high,or they can’t adapt to the demand of large-scale application.This paper introduces an approach to realize the downloading and updating application program by the assistance of CPLD.By using this method,you can use high-capacity external FLASH as a program storage,and realize the updating of program on line in large-scale application with relatively lower cost.According to actual needs,we can design the bootloader program complying with our demands. |
