ARM Cortex-A9
The ARM Cortex-A9 MPCore is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture. It is a multicore processor providing up to 4 cache-coherent cores.
Overview
Key features of the Cortex-A9 core are:- Out-of-order speculative issue superscalar execution 8-stage pipeline giving 2.50 DMIPS/MHz/core.
- NEON SIMD instruction set extension performing up to 16 operations per instruction.
- High performance VFPv3 floating point unit doubling the performance of previous ARM FPUs.
- Thumb-2 instruction set encoding reduces the size of programs with little impact on performance.
- TrustZone security extensions.
- Jazelle DBX support for Java execution.
- Jazelle RCT for JIT compilation.
- Program Trace Macrocell and CoreSight Design Kit for non-intrusive tracing of instruction execution.
- L2 cache controller.
- Multi-core processing.
