IMCOP Memory on DM6446

Santhosh 9921
Prodigy 120 points

Hi,

In DM6446 EVM dsp gel file IMCOP memory map is defined in following way

/* DSP RAM */
    GEL_MapAddStr( 0x11100000, 0, 0x00100000, "R|W|AS4", 0 );   // DSP ImgCop
Imcop memory starts at 0x11100000 and the length 0x00100000. 

Does DSP has direct access to this memory? or Need to use IDMA ?

It is defined under DSP RAM. 

What is the level of this IMCOP memory(L1 or L2)?
Is there any difference between an access to LID SRAM and this IMCOP memory?


Thanks,
Santhosh

    Going by the datasheet memory map on page 20 of the datasheet the memory range at 0x11100000 is reserved for accesses, so I would not suggest trying to use this space as RAM, as it is most likely not entirely RAM, and could be being used by other functionality within the device. In general use of this space is not open to developers, and trying to use it as RAM could lead to problems, if you need details on IMCOP please work with your local TI contact.
