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

When I originally commented I clicked the -Notify me when new surveys are added- checkbox and after this whenever a comment is added I purchase four emails using the same comment. Is there in whatever way you are able to remove me from that service? Thanks! surveillance camera installers

The new Zune browser is surprisingly good, but not as good as the iPods. It works well, but isnt as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser thats not an issue, but if youre planning to browse the web alot from your PMP then the iPods larger screen and better browser may be important. security cameras installation

A few things i have seen in terms of laptop or computer memory is that often there are features such as SDRAM, DDR etc, that must fit in with the specs of the mother board. If the personal computer’s motherboard is reasonably current while there are no operating-system issues, improving the memory literally will take under a couple of hours. It’s one of the easiest computer upgrade types of procedures one can envision. Thanks for sharing your ideas. markham
