How to reduce the CPU consume produced in network transmission(NDK2.0) in DM648 EVM? ie.EMDA3

 1.STATE:before using network  transmission, we can  processing at 60 frames per second in local development environment(DM648 evm) For a video processing projects;But after we add  the network  transmission by the NDK 2.0, we can only  processing at 15 frames per second.

2.Survey: we find the DSP core(DM648) is always busy when the network transmissing.so the  Frame rate reduce.

3. PLATFORM: DM648, CCS4.2, DSP/BIOS 5.4.1, NDK2.0

QUESTION: How to reduce the CPU consume produced by NDK 2.0? 

ie.EMDA3,can we use the EMDA3 to transfer the data block to NETWORK MODULE,instead of using the DSP core.
