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.[1]

Overview

Main article: Comparison of ARMv7-A cores

Key features of the Cortex-A9 core are:[2]

  • Out-of-order speculative issue superscalar execution 8-stage[3] pipeline giving 2.50 DMIPS/MHz/core.
  • NEON SIMD instruction set extension performing up to 16 operations per instruction (optional).
  • High performance VFPv3 floating point unit doubling the performance of previous ARM FPUs (optional).
  • Thumb-2 instruction set encoding reduces the size of programs with little impact on performance.
  • TrustZone security extensions.
  • Jazelle DBX support for Java execution.
  • Jazelle RCT for JIT compilation.
  • Program Trace Macrocell and CoreSight Design Kit for non-intrusive tracing of instruction execution.
  • L2 cache controller (0–4 MB).
  • Multi-core processing.

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[4] and can be clocked at speeds over 1 GHz, consuming less than 250 mW per core.[5]
