Which DVRRDK version are you using. Older RDK version had issue with buffer caching on c674 so the performance issue could be with that. Check with DVRRDK 4.01

Version 2.0. How to apply memory space for the video processing. Utils_memFrameAlloc is right or not?

Version 2 is not supported. Migrate to DVRRDK 4.01. You have to ensure input/output buffers accessed by your algorithm are cached by checking the MAR bits are set for each buffer address range.

cacheMarbit = ti_sysbios_family_c64p_Cache_getMar(pChObj->algMemPtr);

UTILS_assert(cacheMarbit == ti_sysbios_family_c64p_Cache_Mar_ENABLE);
