ARM Cortex-A7

<h2 id="overview">Overview</h2>

Main article: <a href="/facts/Comparison_of_ARMv7-A_cores/j9Jd85YP">Comparison of ARMv7-A cores</a>
It has two target applications; firstly as a smaller, simpler, and more power-efficient successor to the <a href="/facts/ARM_Cortex-A8/vM6beXwg">Cortex-A8</a>. The other use is in the <a href="/facts/Big.LITTLE/YIWq2bWY">big.LITTLE</a> architecture, combining one or more A7 cores with one or more <a href="/facts/ARM_Cortex-A15_MPCore/z1Vccoow">Cortex-A15</a> cores into a <a href="/facts/Heterogeneous_computing/FYkECQ75">heterogeneous system</a>.<a class="footnote-ref" id="fnref:2" href="#fn:2">2</a> To do this it is fully feature-compatible with the A15.
Key features of the Cortex-A7 core are:
