performance drop on porting from EVMDM642 to DM6435

digrexion
Prodigy 200 points

Hi,
  I am porting my application from a EVMDM642 board to a DM6435 board (not an EVM). I am seeing a performance drop by a factor of about 3 to 4. I have the MAR128to159 set to 0x0000ffff, I profiled the code to see if the cache is being thrashed  - about 80% of the cycles are used in processing data. I have included the tcf settings at the end of the message. Is there any other setting that I should be modifying? Any thing I should be trying?
 
  Thanks

    What are you doing with the L2?  I see a few references to "IRAM" in there, but I can't imagine that's filling the entire L2.  Can you make the length of IRAM half it's current size and turn on 64k of L2 cache?  Like this...

    bios.MEM.instance("IRAM").len = 0x00010000;
    bios.GBL.C64PLUSL2CFG = "64k";

    I don't know how your L2 was configured on DM642, but that could make a big difference.

    Hi,

       I am using the tcf for the sample capture application that came with the camera and DM6435 card, I am not sure why  the default setting for L2 was as such. I changed the tcf as suggested , I did not see any improvements in speed. The EVMDM642 used the following settings

    Thanks!
