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

The subsequent time I learn a blog, I hope that it doesnt disappoint me as a lot as this one. I mean, I know it was my option to read, however I really thought youd have something attention-grabbing to say. All I hear is a bunch of whining about something that you possibly can repair when you werent too busy on the lookout for attention. اپلیکیشن مگاپاری

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 Dentist Plano

You undoubtedly ensure it is look simple along with your business presentation however i come across this kind of topic being truly an issue that I think I might never recognize. It appears also complex and extremely wide personally. I will be impatient for your next article, I am going to try to get the hang of it! Dentist in Plano
