DSP/BIOS memory base addresses for c55x seem different than the hardware description

Hello everybody,

I am developing a DSP/BIOS based application on the c5517 chip. For several reasons I have to insert custom dedicated sections in the memory map (for example, a DARAM block entirely dedicated to a timing critical buffer).

When I open the .tcf file though, in the Memory Section Manager, I see that the base addresses listed for every native memory sections are different than the ones specified in the datasheet. For example:

DARAM:

DSP/BIOS base address: 0x60

Datasheet base address: 0xC0

SARAM:

DSP/BIOS base address: 0x8000

Datasheet base address: 0x10000

Could anybody explain why this happens and, if it is a problem, how to solve it? thank you very much
