4 core ARM Cortex-A9 MPCore

The ARM Cortex-A9 MPCore is a multicore processor providing up to 4 cache-coherent Cortex-A9 cores, each implementing the ARM v7 instruction set architecture.

Specifications

  • Designed by: ARM
  • Common manufacturer(s): TSMC
  • CPU clock rate: 800 MHz to 2000 MHz (generic spec, needs confirmation on Vita platform)
  • Instruction set: ARMv7
  • Cores: 1-4
  • L1 cache: 32 kB I/32 kB D
  • L2 cache controller: (0-4 MB)

Debugging/Tracing

CoreSight for Cortex-A series processors enable developers to control (debug) and observe (trace) their Cortex-A processor-based SoC with fewer pins. Cortex-A processor debug and run time control can be performed with only 2 pins using the Serial Wire Debug technology or alternatively using JTAG, when highly compressed real-time trace of the cores and others system trace can be captured on-chip (ETB) or exported through a dedicated trace port (TPIU).
