Configurable and Extensible Processors with Increased Performance

The Cadence® Tensilica® Xtensa® NX processor platform is the newest addition to the Xtensa customizable processors with a performance of over 2GHz suitable for embedded applications that require high performance and large memories, and for performing compute-intensive tasks. The Xtensa NX processor is built on the highly successful energy-efficient Xtensa Instruction Set Architecture (ISA) with various architectural enhancements, including a deeper pipeline, new interrupt architecture, branch prediction, and many more, while offering the same level of configurability and extensibility that Xtensa processors are known for.
