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 (or multiple-issue 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 in ...

* 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.
