1.1 About the processor
The ARM1176JZF-S processor incorporates an integer core that implements the ARM11 ARM
architecture v6. It supports the ARM and Thumb
™
instruction sets, Jazelle technology to enable
direct execution of Java bytecodes, and a range of SIMD DSP instructions that operate on 16-bit
or 8-bit data values in 32-bit registers.
The ARM1176JZF-S processor features:
•TrustZone
™
security extensions
• provision for Intelligent Energy Management (IEM
™
)
• high-speed Advanced Microprocessor Bus Architecture (AMBA) Advanced Extensible
Interface (AXI) level two interfaces supporting prioritized multiprocessor
implementations.
• an integer core with integral EmbeddedICE-RT logic
• an eight-stage pipeline
• branch prediction with return stack
• low interrupt latency configuration
• internal coprocessors CP14 and CP15
• Vector Floating-Point (VFP) coprocessor support
• external coprocessor interface
• Instruction and Data Memory Management Units (MMUs), managed using MicroTLB
structures backed by a unified Main TLB
• Instruction and data caches, including a non-blocking data cache with Hit-Under-Miss
(HUM)
• virtually indexed and physically addressed caches
• 64-bit interface to both caches
• level one Tightly-Coupled Memory (TCM) that you can use as a local RAM with DMA
• trace support
• JTAG-based debug.
Note
The only functional difference between the ARM1176JZ-S and ARM1176JZF-S processor is
that the ARM1176JZF-S processor includes a Vector Floating-Point (VFP) coprocessor.
