11.4. The Diamond 330HiFi audio DSP Core’s Memory Map

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.

Table 11.2. Diamond 330HiFi audio DSP core memory-space assignments

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 ...
