    Hi zhouger,

    In DM6467, there is an ARM9 core and DSP C64x+ core. ARM core is used for data acquisition from peripherals while DSP core is used to perform signal processing on the data acquired. Since the operation of VPIF controller is mainly related to acquiring video data in NTSC/PAL format with varying resolutions , etc. and transferring video output, afaik, you cannot use VPIF directly with C64x+ core. Also, VPIF controller directly copies captured video data into external SDRAM eg. DDR, which is again accessed using the ARM( core.

    Hope this helps.

    Regards,

    Sid

    Zhouger,

    Sid is correct. For more information, please review section 3.4 of the datasheet.
