ARM Cortex-A9 GudangMovies21 Rebahinxxi LK21

      The ARM Cortex-A9 MPCore is a 32-bit multi-core processor that provides up to 4 cache-coherent cores, each implementing the ARM v7 architecture instruction set. It was introduced in 2007.


      Features



      Key features of the Cortex-A9 core are:

      Out-of-order speculative issue superscalar execution 8-stage pipeline giving 8.50 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 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 and can be clocked at speeds over 1 GHz, consuming less than 250 mW per core.
