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

Nice post. I learn something more challenging on distinct blogs everyday. It will always be stimulating to read content off their writers and practice a little something from their store. I’d choose to use some with all the content in my small weblog whether you do not mind. Natually I’ll provide a link on your own internet weblog. Many thanks sharing. gasing777

Wow! This could be one particular of the most helpful blogs We’ve ever arrive across on this subject. Actually Great. I’m also an expert in this topic therefore I can understand your hard work. terong123

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. terong123
