摘要
DSP系统设计中,系统在加电后往往要脱离主机和仿真器自启动引导加载,主要介绍了在上电复位时DSP可以由EMIF引导自动搬移CE1起始地址1kbyte到地址Ox00的思想,解决了存放在FLASH中的BOOTLOAD引导程序复制到DSP的内部RAM起始地址去执行的问题,实现了由BOOTLOAD引导程序从FLASH中加载应用程序的功能,完成了DSP的FLASH引导启动,该思路下设计的FLASH自启动设计已在SAR数据存储系统上应用,运行良好.
In the DSP system design,the bootstrapping without the host and emulator after power on is needed in the system,which is essential aspect in DSP system design.The idea of moving automatically the CE1 starting address to the address Ox00 by EMIF is introduced.The problem of BOOT program stored in the FLASH which is copied to starting address of RAM in the DSP to perform is solved.The functions of the boot program loaded from FLASH application by BOOTLOAD is completed.The BOOTLOAD procedures under the design ideas have been prepared in the application of SAR data storage system,running well.
