Overview

De-Facto Standard in Customizable Processors

Cadence® Tensilica® Xtensa® processors combine the best of CPUs, GPUs, FPGAs, and dedicated custom RTL in ASICs/SoCs and enable the development of energy-efficient domain-specific processors that offer high performance, flexibility for future-proofing, and more importantly, can be tailored for your specific application requirements. Xtensa processors are based on a modular, highly flexible 32-bit RISC architecture that can easily scale from a tiny, cache-less controller or task engine to a high-performance SIMD/VLIW DSP. Furthermore, to facilitate the development of SoCs for functional safety, the Xtensa architecture supports a windowed watchdog timer (WWDT) and FlexLock including dual-core lockstep (DCLS).
