use coprocessor for image processing functions

Hi,

Thanks for your post.

In general, the scaling is to be done on the DSP or using the Hardware accelerators. The downsizing is available as the VDCE driver and it is totally dependent on ARM cycles. This is on DM6467T. Both upsizing and downsizing can be implemented using the DSP C64x based algorithms. However any resolution more than 1080p will have the limitation on the DSP cycles. Other platforms like DM365, DM6446 and DM6437 have both upsizing and down sizing possible on hardware.

The H.264 compression is done by the HW accelerator on DM6467 and the resizing has to be done by the VDCE or DSP once the frame is decoded by the accelerator on the DM6467T.

The video analytics available as part of DM6467 will work the same way as on DM6467T. The DVSDK will include the Video compression software, PSP releases and demos. Check the DVSDK contents.
