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

Thank you for the sensible critique. Me & my cousin were just preparing to do some research on this. We grabbed a book from our area library but I think I learned more from this post. I am very glad to see such fantastic info being shared freely out there… Nitric Boost Ultra

I am writing to let you understand what a extraordinary discovery my cousin’s daughter had going through your web page.

You really surpassed her expected results. Many thanks for giving the helpful, healthy, revealing as well as cool tips about that topic to Evelyn. Nitric Boost Ultra

Things i have seen in terms of computer memory is the fact there are technical specs such as SDRAM, DDR and many others, that must match the features of the motherboard. If the personal computer’s motherboard is fairly current while there are no operating-system issues, changing the memory literally takes under sixty minutes. It’s one of several easiest personal computer upgrade techniques one can picture. Thanks for giving your ideas. Nitric Boost Ultra

It is very interesting topic you’ve written here . The truth I’m not related to this, but I think is a good opportunity to learn more about, And as well talk about a different topic to which I used to talk with others Nitric Boost Ultra

The processor or CPU is the brains of the personal computer – it does most of the calculations your video game titles need to have to run (with the movie card undertaking most of the graphics function). With it getting such an critical part, you would instinctually go for the fastest – and most pricey – processor you could find, but there is a improved alternate to blowing hard cash on one thing that will be obsolete in a year: receiving a processor that will play tomorrow’s video game titles at a low cost is the sweet spot for any gaming computer.
