1.3.1 MICROPROCESSOR

The key features of this microprocessor include:
• The ARM CortexTM-A8 processor is the first application processor based on ARMv7 architecture.
• With the ability to scale in speed from 600 MHz to 1 GHz (or more), the ARM CortexTM-A8 processor meets
the requirements of power-optimized mobile devices, which require operation in less than 300mW; and
performance-optimized consumer applications require 2000 Dhrystone MIPS.
• Supports first superscalar processor featuring technology from ARM for enhanced code density and
performance, NEONTM technology for multimedia and signal processing, and Jazelle® RCT technology for
ahead-of-time and just-in-time compilation of Java and other byte code languages.
• Other features of ARM CortexTM-A8 include:
− Thumb-2 technology for greater performance, energy efficiency, and code density
− NEONTM signal processing extensions
− Jazelle RCT Java-acceleration technology
− TrustZone technology for secure transactions and DRM
− 13-stage main integer pipeline
− 10-stage NEONTM media pipeline
− Integrated L2 Cache using standard compiled RAMs
− Optimized L1 caches for performance and power
