摘　　要：为提高DSP的自举速度和程序运行效率,提出一种改进的TIC6xDSP系统的快速自举方式。以TMS320C6455为例,详细分析TIC6xDSP自举的基本原理、硬件接口设计、Flash烧写固化以及软件实现全过程。针对现有解决方案存在的弊端,从加载模式设计、引导程序编写以及目标代码整合3方面进行改进。结果表明:该方法能极大地提高DSP的自举速度和程序运行效率,降低程序员对DSP的开发难度。For accelerating DSP boot speed and improving program running efficiency, put forward an improved TIC6xDSP system fast boot mode. Taking TMS320C6455 as example, the whole process of TIC6xDSP’s boot is analyzed, including fundamental principle, hardware and interface design, flash burn and software design. Meanwhile, aiming at the problem of existing solutions, 3 aspects are proposed for improving, such as loading mode design, boot programming and integration of destination code. The results show that the method can greatly accelerate DSP boot speed and improve program running efficiency, and reduce difficulties for DSP research and development.
