CNL Memory

8000 0000h

Aliasing to A000 0000h - BFFF FFFFh range (non L1 cacheable).

A000 0000h

L2 cacheable memory (L1 cacheable).

B000 0000h

L2 uncacheable memory (L1 cacheable). IMR (4MB size), see IMR Allocation.

BE00 0000h

L2 local HPSRAM (L1 cacheable). Seen as 8MB of virtual memory space (47 * 64KB).


By default, address virtualization is disabled. The Translation Lookup Buffer (TLB) entries for populated HPSRAM banks have the same values for virtual addresses and physical addresses.

BE80 0000h

L2 local LPSRAM (L1 cacheable). Accessed using physical addresses (1 * 64KB).

BEFE 0000h
