The ARM Cortex-A9 MPCore is a 32-bit multi-core processor that provides up to 4 cache-coherent cores, each implementing the ARM v7 architecture instruction set. It was introduced in 2007.
Features
Key features of the Cortex-A9 core are:
*
Out-of-order speculative issue superscalar
A superscalar processor is a CPU that implements a form of parallelism called instruction-level parallelism within a single processor. In contrast to a scalar processor, which can execute at most one single instruction per clock cycle, a sup ...

NEON
Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered (along with krypt ...
SIMD
Single instruction, multiple data (SIMD) is a type of parallel processing in Flynn's taxonomy. SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should ...
instruction set extension performing up to 16 operations per instruction (optional).
* High performance VFPv3 floating point unit doubling the performance of previous ARM FPUs (optional).
*
Thumb-2
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computer (RISC) instruction set architectures for computer processors, configured ...
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 (0–4 MB).
* Multi-core processing.
ARM states that the TSMC 40G hard macro implementation typically operates at 2 GHz; a single core (excluding caches) occupies less than 1.5 mm
2 when designed in a TSMC 65 nanometer (nm) generic process and can be clocked at speeds over 1 GHz, consuming less than 250 mW per core.
