hi, all
I met low performance on c674x in DM816x on DVR_RDK. it took 12 ms to memcpy 2MB data when it took 2 ms copy the same data on dm814x DSP.
I'm sure the L2 cache is enabled, here is my FC_RMAN_IRES_c6xdsp.cfg
/* CPU access code and data - 0x80000000 cache enable */
Cache.MAR128_159 = 0xFFFFFFFF;
/* TILER memory cache disabled - 0xA0000000*/
Cache.MAR160_191 = 0xFFFFFFFF;
if I disable the cache, it will take more than 60ms.
I am sincerely looking forward to your reply.
Regards
