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.

Key features of the Cortex-A9 core are:

ARM states that the TSMC 40G hard macro implementation typically operating at 2 GHz; a single core (excluding caches) occupies less than 1.5 mm² 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.

Several system on a chip (SoC) devices implement the Cortex-A9 core, including:

RZ/A1L plus Ethernet AVB support and a JPEG codec unit, 3MByte RAM SoC

MINI4418

NanoPi-2 Fire NanoPi M2 NanoPC-T2
