L2 Cache location in internal RAM

I'm using a 6482.  I want to cache external RAM using a 32kbyte L2 Cache in internal memory.

The examples in TMS320C64x+ DSP Cache User's Guide show the L2 Cache at the high addresses of internal memory (0x9F8000 to 0xA00000 for 32-kbyte cache).

Does L2 Cache have to be in the high addresses of internal RAM?  Or can it be at any arbitrary address (like 0x9F0000) instead?

thanks,

Brad
