Processor Configuration with Chris Rowen
The Xtensa Processor Generator
A “generic" Xtensa processor does not exist. Each instance of the processor architecture is uniquely tuned by the system designer to ideally fit the SOC’s targeted application.
The designer can select from a broad selection of predefined standard RISC microprocessor options and can add instructions and register extensions to the tailored processor. Or the designer can use Tensilica's XPRES Compiler to automatically tailor the processor to optimize existing C/C++ code.
The Xtensa Processor Generator then creates the complete processor solution set - pre-verified processor hardware description in source RTL (Verilog or VHDL), plus supporting hardware implementation methodology scripts. This complete package includes software development tools including commercial RTOS support, and comprehensive system modeling and modeling co-verification support.
