ARM11 Overview

The ARM11 processor family provides the engine that powers many smartphones in production today; it is also widely used in consumer, home, and embedded applications. It delivers extreme low power and a range of performance from 350 MHz in small area designs up to 1 GHz in speed optimized designs in 45 and 65 nm. ARM11 processor software is compatible with all previous generations of ARM processors, and introduces 32-bit SIMD for media processing, physically tagged caches to improve OS context switch performance, TrustZone for hardware-enforced security, and tightly coupled memories for real-time applications.
