Table 2-3 Supported ARM architectures and example processors (continued)
Architecture Description Example processors
6Z ARMv6 with Security Extensions ARM1176JZF-S,
ARM1176JZ-S
7 ARMv7 with Thumb-2 only and without hardware divide
7-A ARMv7 application profile supporting virtual MMU-based memory
systems, with ARM, Thumb-2, and Thumb-2EE instruction sets, DSP
support, and 32-bit SIMD support
7-R ARMv7 real-time profile with ARM, Thumb-2, DSP support, and 32-bit
SIMD support
Cortex-A8, Cortex-A9
Cortex-R4, Cortex-R4F
7-M ARMv7 micro-controller profile with Thumb-2 only and hardware divide Cortex-M3, SC300
a. The ARM compiler cannot generate Java bytecodes.
Note
ARMv7 is not an actual ARM architecture. --cpu=7 denotes the features that are
common to all of the ARMv7-A, ARMv7-R, and ARMv7-M architectures. By
definition, any given feature used with --cpu=7 exists on all of the ARMv7-A,
ARMv7-R, and ARMv7-M architectures.
Default
If you do not specify a --cpu option, the compiler assumes --cpu=ARM7TDMI.
To get a full list of CPU architectures and processors, use the --cpu=list option.
Usage
The following general points apply to processor and architecture options:
Processors
• Selecting the processor selects the appropriate architecture,
Floating-Point Unit (FPU), and memory organization.
• The supported --cpu values include all current ARM product
names or architecture versions.
Other ARM architecture-based processors, such as the Marvell
Feroceon and the Intel XScale, are also supported.
