12.4. The Diamond 545CK DSP Core’s Memory Map

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.

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 ...
