AM572X VIP & VPDMA & VPE

Dear Sir,

I got my AM572x EVM from TI website running Processor SDK version "ti-processor-sdk-linux-am57xx-evm-02.00.01.07",

VIP data will be in VPDMA, then data through L3_MAIN bus go to VPE,

Could I have 4 channel VIP input 1080p, then do 4 VPE down scaler for 4 VIP data to 320x240 at the same time ?

    You can do 4x1080p30 capture. VPE scaler at driver level can do 1080p to QVGA scaling at 120 fps. The perfromance has not yet been validated at application layer.

    VIP engine also has scaler for each slice. It can only downscale on the fly and write the scaled output to the memory. VIP driver doesn't support scaling feature in proc sdk 2.01. It is expcetd to be supported in next proc SDK release. In this VIP driver, if you want to downscale using VIP engine, you will only get the downscaled output written to memory and won't get the original resolution image.
