TI-EZSDK support for 2592x1944 5MP video input

Other Parts Discussed in Thread: TMS320DM8148

Dear all,

We are designing a new project that intend to use TMS320DM8148 chipset and based on TI-EZSDK 5_05_02_00.

We intend to capture video from a CMOS via video input port. The video is 2592 x 1944 5MP resolution in RGB format.

Like to find out from TI, if this resolution supported? Is the M3 firmware provided within TI-EZSDK sufficient to support this?

As the technical reference manual SPRGZ8D page 1763 states that its up to 1080p.

Extracts from TRM:

Two independent Video Capture input ports up to 165MHz, each VIP instance supports scaling, pixel
format conversion, and up to 1 1080P60 or 8-channel multiplexed D1 data.

Thank you.

Regards

May

    May,

    You may not be able to support 2592x1944@60fps. The maximum supported resolution is WUXGA (1920x1200) which requires close to 154MHz with reduced blanking. I believe your clock requirement is much higher than that, which will not be possible using HDVPSS. However you can try to capture using ISS subsystem which should support more than this resolution. But I'm not really sure about the ISS driver support. EZSDK 5_05 doesn't provide drivers for ISS subsystem.

    Hi Renjith,

    Thank you for your reply.

    Your reply helped to clear the doubt about using HDVPSS for this resolution.
