Simultaneous H.264 Encode & Decode @ 30fps using dm6437

Harshavardhan Thakar
Prodigy 45 points

Hello,

I have a camera input 8 bit parallel in the BT.656 format @ 30fps. The resolution is 680H x 512V.

1.) The data has to encoded in the H.264 format, encrypted using the AES128bit encryption and stored in the local HDD.

2.) Simultaneously the data has to be displayed in the local LCD after reading the HDD. i.e. (decrypt & decode)

3.) I have shortlisted the dm6437 for this application.

Please advise.

Thank you,

Harshavardhan.

    Harshavardhan,

    There are two points to consider :

    1. The CPU cycles required for each of encrypt, decrypt, encode and decode operation of the video buffer.

    2. Analyze all the data flows in the system -  peripherals to memory and viceversa. After they are summed, it gives info about required system bandwidth and memory bandwidth.

    Have you considered a comparable part - DM365. It has an ARM9 instead of DSP C6x and also has an additional hardware accelerator.

    What  O.S., software libraries are you planning to use ?
