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

Do you mind if I quote a couple of your articles as long as I provide credit and sources back to your blog? My website is in the very same area of interest as yours and my users would really benefit from a lot of the information you present here. Please let me know if this okay with you. Regards! 33win2

Hello I found the Free Simple Shopping Icons Download | Design, Tech and Internet post very interesting therefore I’ve included our track-back for it on my own webpage, continue the great job:) 33win2

Thank you for another excellent article. Exactly where else could anybody get that kind of data in this kind of a perfect way of writing? I have a presentation subsequent week, and I am to the appear for such information and facts. 33win2

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. 33win2

Thanks a lot for being our mentor on this niche. I enjoyed your current article very much and most of all cherished how you really handled the aspect I considered to be controversial. You are always quite kind to readers much like me and let me in my everyday living. Thank you. 33win2

Hi there! This is kind of off topic but I need some advice from an established blog. Is it very hard to set up your own blog? I’m not very techincal but I can figure things out pretty quick. I’m thinking about setting up my own but I’m not sure where to start. Do you have any points or suggestions? Thank you 33win2
