The Diamond 545CK DSP core’s address space is mapped to the local memories and the PIF bus as shown in Table 12.2. Note that the Diamond 545CK’s instruction-RAM and two data-RAM memory spaces are adjacent so they form one contiguous 384-Kbyte memory block from 0x3FFC0000 to 0x4001FFFF.
|Local memory||Start address||End address|
|Local instruction RAM||0x40000000||0x4001FFFF|
|Local data RAM #1||0x3FFE0000||0x3FFFFFFF|
|Local data RAM #2||0x3FFC0000||0x3FFDFFFF|
The Diamond 545CK DSP core has a 32-bit, 4-Gbyte address space, so additional memory can be attached to its PIF bus if needed. However, the address spaces dedicated to local memory are hardwired to the appropriate ...
