ARM11 Family

Based on the ARM11 microarchitecture, the ARM11 processor family comprises a range of high performance microprocessors, delivering up to 740 Dhrystone 2.1 MIPS in 0.13µ process technology. The family comprises four main product lines, the ARM1136J(F)-S processor, the ARM1156T2(F)-S processor and the ARM1176JZ(F)-S^TM processor, each optimized for the specific requirements of different market segments, and the ARM11 MPCore^TM multiprocessor. 

TrustZone^TM and IEM Enabled Applications Processors for Consumer and Wireless
The ARM1176JZ-S and ARM1176JZF-S processors featuring ARM TrustZone technology, and ARM Jazelle® technology for efficient embedded Java execution, are designed for use as applications processors in consumer and wireless products. ARM 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.

Both processors feature the ARMv6 instruction set architecture, with media processing extensions, ARM Jazelle technology, and ARM Thumb^® for compact code. The ARM1176JZF-S processor also features an integrated floating point coprocessor, which makes it particularly suitable for embedded 3D-graphics applications. These are also the first processors to integrate support for ARM Intelligent Energy Manager (IEM) technology which can reduce processor energy consumption by up to 60% - making them ideal for cell-phone, PDA, hand-held game and other portable consumer devices.

These processors feature AXI interfaces compatible with the latest AMBA^TM 3 AXI^TM specification, and offering higher system bus bandwidth with fewer bus layers and rapid timing closure.

High Performance Processors for Automotive, Data Storage, Imaging and Embedded Control
The ARM1156T2-S and ARM1156T2F-S processors incorporate the latest 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 at the same time delivering up to 38 percent better performance than existing Thumb technology-based solutions. 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 ARM1156T2F-S processor includes an integrated floating point coprocessor - ideal for embedded control applications developed from mathematical models. Both processors feature an enhanced Memory Protection Unit (MPU) and offer an ideal upgrade path for embedded control applications currently using ARM946E-S^TM, ARM966E-S^TM 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.

Processors for Network Infrastructure, Consumer, and Automotive Infotainment
The award-winning ARM1136J-S and ARM1136JF-S processors, feature the ARMv6 instruction set with media extensions, ARM Jazelle technology, ARM Thumb code compression, and optional floating point coprocessor. As with all ARM11 family processors, media processing extensions offer up to 1.9x acceleration of media-processing tasks such as MPEG4 encode, instruction and data cache sizes are configurable, and optional Tightly Coupled Memories can be added to accelerate interrupt handling and data-processing. These processors feature AMBA 2 AHB interfaces compatible with a wide range of system IP and peripherals.

ARM11 MPCore Multiprocessor
The ARM11 MPCore synthesizable multiprocessor is based on the ARM11 microarchitecture and can be configured to contain between one and four processors delivering up to 2600 Dhrystone MIPS of performance.

The ARM11 MPCore multiprocessor solution delivers greater performance at lower frequencies than comparable single processor solutions, bringing significant cost savings to system designers, while maintaining full compatibility with existing EDA tools and flows.  The ARM11 MPCore processor also simplifies otherwise complex multiprocessor designs, reducing time-to-market and design costs.

Supporting Products
The ARM11 family of processors is complemented by the range of ARM11 PrimeXsys Platforms and ETK11 which provide a foundation for efficient and rapid implementation of ARM11 core-based designs. ARM PrimeXsys Platforms provide a comprehensive set of peripherals, pre-configured with a flexible high-performance interconnect, and are readily extendable with customers’ own or third party IP.

The CoreSight range of embedded debug products provides the ability to trace execution of the ARM11 processors in real-time and gives debug visibility of the entire ARM11 SoC.

A wide range of development tools is also available from ARM and third parties.

Applications:

*ARM1176JZ-S and ARM1176JZF-S processors are also suitable for all application areas covered by ARM1136J-S, but with the added advantage of TrustZone technology where a trusted computing platform is required.
