The Diamond 330HiFi audio DSP core’s address space is mapped to the local memories and the PIF bus as shown in Table 11.2. Note that the Diamond 330HiFi’s instruction RAM and 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 330HiFi audio 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 ...
