11.6. The Diamond 330HiFi audio DSP Core’s (Region-Protection Unit)

The Diamond 330HiFi audio DSP core uses the same region-protection unit (RPU) discussed in Chapter 8 on the Diamond 212GP processor.

Figure 11.7 shows how the Diamond RPU divides the Diamond 330HiFi audio DSP core’s 4-Gbyte memory space into eight equally sized, 512-Mbyte regions. The Diamond 330HiFi audio DSP core’s local data-memory address space and the address space assigned to the XLMI port fall into memory-protection region 1. Its local instruction-memory address space falls into memory-protection region 2. Thus the RPU can prevent accidental writes to instruction memory through the proper use of its protection mechanisms. The Diamond 330HiFi audio DSP core’s non-local ...
