7.2. Diamond 108Mini Processor Core Interfaces
The Diamond 108Mini processor core has a number of interfaces for high-bandwidth I/O, as shown in Figure 7.2. These interfaces include a 32-bit implementation of the Xtensa PIF (main) bus and separate memory interfaces for one local instruction-memory block and two local data-memory blocks. Each of the three local-memory interfaces can accommodate memories as large as 128 Kbytes, for a total of 384 Kbytes of local memory.
Figure 7.2. The Diamond 108Mini processor core has three 32-bit buses that can be used for attaching local memories and a 32-bit implementation of the Xtensa PIF (main processor interface) bus for attaching additional memory and other system devices.
