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.
