ARM11 Processor Family

Applications Processors for Consumer, Wireless, and Automotive Infotainment

• ARM1176JZ(F)-S and ARM11 MPCore™ Processors
  • Designed for use as applications processors in consumer and wireless products
  • Both processors feature the ARMv6 instruction set architecture, with media processing extensions, ARM Jazelle^® technology, and ARM Thumb^® for compact code.
  • In the ARM11 processor family, only the ARM1176JZ(F)-S processor has ARM TrustZone™ technology. TrustZone technology provides support within the CPU and platform architecture for building the trusted computing environments required to enable protection of critical system functions from downloaded applications, copyright protection of downloaded media, safe over-the-air system upgrades.
• Scalable Multicore performance with ARM11 MPCore Processor
  • The ARM11 MPCore synthesizable multiprocessor, based on the ARM11 microarchitecture, can be configured to contain between one and four processors delivering up to 2600 Dhrystone MIPS of performance.

• ARM1136J(F)-S Processor
  • Also designed for use as applications processors; includes many features of the ARM1176JZ(F)-S processor
  • Does not include AMBA^® 3 AXI™ bus or TrustZone
  • Some users implement the ARM1136J(F)-S processor for compatibility with existing AMBA AHB bus peripherals from their ARM9 processor-based SoC designs
  • Software-compatible migration path to latest generation ARM Cortex-A class processors

High Performance Processors for Automotive, Data Storage, Imaging and Embedded Control

• ARM1156T2-S Processor
  • First ARM processor to incorporate ARM Thumb-2 technology for even higher code density and instruction set efficiency.
    • Thumb-2 technology uses 31 percent less memory than pure 32-bit code to reduce system cost, while delivering up to 38 percent better performance than existing Thumb technology.
  • These processors also feature optional parity protection for caches and Tightly Coupled Memories (TCM), and non-maskable interrupts, making them ideal for embedded control applications where high reliability or high availability are paramount.
  • The ARM1156T2-S processors feature an enhanced Memory Protection Unit (MPU) and offer an ideal upgrade path for embedded control applications currently using ARM946E-S, ARM966E-S or older 16-bit processors.
  • These processors feature AMBA 3 AXI specification interfaces, offering higher system bus bandwidth with fewer bus layers and rapid timing closure.
  • Software-compatible migration path to latest generation ARM Cortex-R class processors

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.

System IP components are essential for building complex system on chips and by utilizing System IP components developers can significantly reduce development and validation cycles, saving cost and reducing time to market.

Tools Support

All ARM processors are supported by the ARM RealView^® portfolio of development tools, as well as a wide range of third party tools, operating system and EDA vendors. ARM RealView tools are unique in their ability to provide solutions that span the complete development process from concept to final product deployment.
