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

Thanks for the tips you have provided here. One more thing I would like to mention is that laptop memory requirements generally increase along with other breakthroughs in the engineering. For instance, as soon as new generations of processors are introduced to the market, there is usually a matching increase in the shape demands of all computer system memory plus hard drive room. This is because the application operated by these cpus will inevitably boost in power to leverage the new engineering. Coffee loophole

A well written article, I just passed this onto a workfellow who was doing somewhat analysis on this. And he indeed purchased me dinner because I discovered it for him…. .. therefore let me reword that: Thnkx for the treat however yeah Thnkx for spending the time to talk about this, I feel strongly concerning it and love reading more on this topic. If doable, as you gain expertise, would you mind updating your blog with more details? it is extraordinarily useful on behalf of me. massive thumb up for this blog Coffee loophole

What i don’t realize is in fact how you’re no longer actually much more smartly-liked than you may be right now. You are very intelligent. You understand thus significantly on the subject of this matter, produced me for my part imagine it from so many various angles. Its like men and women are not involved unless it is something to do with Lady gaga! Your personal stuffs nice. Always maintain it up! Coffee loophole

Good day! This post could not be written any better! Reading this post reminds me of my previous room mate! He always kept chatting about this. I will forward this write-up to him. Fairly certain he will have a good read. Thanks for sharing! The Divine Prayer Reviews

If you’re still on the fence: grab your favorite earphones, head down to a Best Buy and ask to plug them into a Zune then an iPod and see which one sounds better to you, and which interface makes you smile more. Then you’ll know which is right for you. The Divine Prayer Reviews
