摘　　要：引导加载是DSP系统设计中必不可少的重要环节。本文在设计了由TMS320VC5502 DSP和FLASH存储器构成的最小系统的基础上,设计了一套并行引导加载方案,介绍了FLASH的在系统编程技术和生成引导表的具体方法,最终实现了应用程序的引导加载和系统的脱机运行。The consideration of bootloader is absolutely necessarily in the design of DSP systems. By designing a minimum system using TMS320VC5502 and flash memory, this article designs an integrated scheme of its parallel bootloader method. In addition, the ISP （In System Programming） technology for flash memory and the method of creating a boot table is discussed. Finally, application codes are successfully loaded from outer flash into internal RAM on the system, and the off-line execution is implemented.
