Xtensa LX4 Microprocessor Data Book

Using Tensilica's hardware and software development tools, the configurable and extensible Xtensa LX4 processor lets the designer mold the processor to exactly fit the application. Highlights of the LX4 processor include:

• Highly efficient, small, low-power base 32-bit modern architecture
• Configurable over a wide range of options – get just what you need
• Configure processor as a multi-issue VLIW using FLIX architecture
• Extend processor with application-specific instructions, execution units, and register files
• Unlimited I/O bandwidth with designer-defined FIFO, GPIO, and Lookup interfaces
• Automated fine-grained clock gating for ultra-low power
• Designer-selectable 5-stage or 7-stage pipeline depth

This manual describes all aspects of the Xtensa LX4 processor.
