4.11. Diamond Standard Series Processor Cores—Dealing with Complexity

TIE expands the processing capabilities of microprocessor cores far beyond that of fixed-ISA processors. The combination of Xtensa processor configurability and TIE-based extensibility creates a huge, multidimensional design space, as illustrated by Figure 4.8.

Figure 4.8. Processor configurability and TIE-based extensibility create a huge, multidimensional design space.

Figure 4.8 is divided into the Xtensa technology’s four main configurability and extensibility quadrants: configurable features, instruction extensions, processor-state (register and ...
