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

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 รูปซุปเปอร์แมนการ์ตูน

A few things i don’t understood is at truth how you are now not necessarily really a lot more neatly-favored as compared to you may be right now. You might be so smart. You already know thus considerably concerning this matter, taught me to be separately consider it from the large amount of different sides. It’s just like people are certainly not intrigued until it is something to accomplish along with Girl coo! Your individual stuffs outstanding. All the time look after up! โหลดเกม don't starve
