Abstract: The TMS320DM642 Digital Media Processor is based on the C64x CPU, a member of the C6000 DSP family. The DM642 integrates a number of peripherals to address the development of video and imaging applications. The development process and implementation methods of the multi-level bootloader for bulk Flash memory bootloading on DM642 Platform was introduced in detail,and a new way to develop top multimedia embedded system based on TMS320DM642 Digital Media Processor was given. It is proved that the way introduced here is practical and has a good prospect.

Key words: digital media processor, bulk FLASH memory, bootload
