The Diamond 570T CPU core’s address space is mapped to the local memories and the PIF bus as shown in Table 10.2. Note that the Diamond 570T’s instruction- and data-RAM memory spaces are adjacent so they form one contiguous 256-Kbyte memory block from 0x3FFE0000 to 0x4001FFFF. The address space for the Diamond 570T’s XLMI port is mapped just below and contiguous with the address space for the data-memory block. All of the Diamond 570T CPU core’s three local-memory spaces thus form one contiguous 384-Kbyte address space from 0x3FFC0000 to 0x4001FFFF.
|Local memory||Start address||End address|
|Local instruction RAM||0x40000000||0x4001FFFF|
|Local data RAM #1||0x3FFE0000 ...|
