ARM Cortex A9 CPU subsystem

Processor subsystem based on the processor ARM Cortex A9, and has a dual-core configuration.

Key Features:

Each core has the following features:

  • ARM v7 processor with a clock frequency of 600 MHz
  • 32K L1 Instruction Cache parity
  • 32 KB L1 data cache parity
  • Built-in FPU operations for single and double precision data scalar floating-point
  • The memory management unit (MMU)
  • Instruction set support for ARM, Thumb2 and Thumb2-EE
  • Program Trace Macrocell (PTM) and CoreSight © component for software debugging
  • 32-bit timer with 8-bit divisor
  • The internal watchdog (also works as a timer)

Dual core configuration completes a common set of components:

  • Snoop Control Unit (SCU) for controlling communication between processes, cache memory and cache memory and transfer RAM, cache coherency
  • Shared interrupt control unit (GCA) is configured to support 128 independent interrupt sources with software configurable priorities and routing between the two nuclei
  • 64-bit global timer with an 8-bit divisor
  • Accelerator coherence port (ACP)
  • Support for parity for fault detection performance for other internal memories
  • 512 KB single 8-way associative L2 cache with ECC support
  • L2 cache controller based on ARM PL310 IP released
  • Dual asynchronous 64-bit AMBA 3 AXI interface with the ability to filter on the second use one port to access DDR memory
  • JTAG-interface and monitor port: debug and trace may be prohibited by OTP

This is the suitable blog for anybody who needs to seek out out about this topic. You notice so much its virtually laborious to argue with you (not that I really would want…HaHa). You undoubtedly put a brand new spin on a subject thats been written about for years. Great stuff, just great! email marketing
