Data transfer through DRAM is faster than OCM?

Hi,

 

I tried out a simple application to read and write 8KB of data from and to DRAM as well as OCM. Found that OCM access was slower than DRAM. I am puzzled. I suppose OCM access must be faster than DRAM.

 

Are there an specific optimizations done for R5 DRAM access at the hardware? 

 

Note: L1 cache is enabled for transfers to both memories.

 

Regards,

Kiran
