The actual application processor cores are [http://www.arm.com/products/processors/cortex-a/cortex-a9.php Cortex A9], which is common in modern high performance embedded devices like cell phones and tablets. The [http://infocenter.arm.com/help/topic/com.arm.doc.ddi0388i/index.html Technical Reference Manual] gives a good overview of the specific processor features and is a good reference for what ARMv7 implementation specific features are enabled. The Vita cores have a MIDR value of <code>0x412FC09A</code>, meaning it is Cortex A9 r2p10. Indeed there are usage of undocumented CP15 registers.
Another manual that's important is the [http://infocenter.arm.com/help/topic/com.arm.doc.ddi0407i/index.html MPCore Technical Reference Manual] which is specific to the multi-core system the Vita uses. The main information of use are descriptors for the private memory region defined with the <code>PERIPHBASE</code> signal. This is mapped to [[Physical Memory|physical address]] <code>0x1A000000</code>.

As part of the Cortex A9 MPcore, the Vita also implements the [http://www.systems.ethz.ch/sites/default/files/file/aos2012/ReferenceMaterial/InterruptHandling/GIC_architecture_spec_v1_0.pdf Generic Interrupt Controller Architecture]. More information on interrupts can be found [[Interrupts|here]].

The Vita uses the [http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0246a/index.html PL310] L2 cache is is [[Physical Memory|mapped]] to <code>0x1A002000</code>.
