10.3. The Diamond 570T CPU Memory Map
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 ... |
