Features

Key features of the Cortex-A9 core are: [3]

ARM states that the TSMC 40G hard macro implementation typically operates at 2 GHz; a single core (excluding caches) occupies less than 1.5 mm2 when designed in a TSMC 65 nanometer (nm) generic process [5] and can be clocked at speeds over 1 GHz, consuming less than 250 mW per core. [2]
