Cortex-A series processors

ARM documentation set for the ARM Cortex-A series of CPU processor cores, including ARM Cortex-A5, ARM Cortex-A8, ARM Cortex-A9 MPCore, ARM Cortex-A9 Single Core processors.

The ARM Cortex-A Series is a family of applications processors for complex OS and user applications. The Cortex-A series processors support the ARM, Thumb, and Thumb-2 instruction sets.

• The ARM Cortex-A15 processor has an out-of-order superscalar pipeline with a tightly-coupled low-latency level-2 cache which can be up to 4MB in size. The Cortex-A15 processor implements the ARMv7-A architecture.
• The ARM Cortex-A9 processor is a very high-performance, low-power, ARM macrocell with an L1 cache subsystem that provides full virtual memory capabilities. The Cortex-A9 processor implements the ARMv7-A architecture and runs 32-bit ARM instructions, 16-bit and 32-bit Thumb instructions, and 8-bit Java bytecodes in Jazelle state.
• The ARM Cortex-A8 processor is a high-performance, low-power, cached application processor that provides full virtual memory capabilities.
• The ARM Cortex-A5 processor is a high-performance, low-power, ARM macrocell with an L1 cache subsystem that provides full virtual memory capabilities. The Cortex-A5 processor implements the ARMv7 architecture and runs 32-bit ARM instructions, 16-bit and 32-bit Thumb instructions, and 8-bit Java bytecodes in Jazelle state. The Cortex A-5 is the smallest Cortex-A processor.
