The Cortex-A9 processor is a high-performance, low-power, ARM macrocell with an L1 cache subsystem that provides full virtual memory capabilities. The Cortex-A9 processor implements the ARMv7-A architecture and runs 32-bit ARM instructions, 16-bit and 32-bit Thumb instructions, and 8-bit Java bytecodes in Jazelle state.

Figure 1.1 shows a Cortex-A9 uniprocessor in a design with a PL390 Interrupt Controller and an L2C-310 L2 Cache Controller,
