ARM11 Processor Family

ARM11 Processor Family Image
The ARM11™ processor family provides the engine that powers many smartphones in production today and 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.

Cortex Alternative

The Cortex™-A5 processor is a related follow-on product to the ARM1176. The Cortex-A5 processor offers similar speed to ARM11™ processors, at lower power and smaller die area, with the ARMv7 benefits of NEON™, and TrustZone®, as well as a more advanced AMBA® AXI™ bus. Cutting edge new SoC designs for are starting now based on the ARM Cortex-A5 processor, however some SoC designs are still starting with ARM1176 processor where cost and minimal risk are important considerations.

System IP

The ARM1176 processor is commonly integrated with many other IP blocks to optimize the SoC for performance, power, and security.
