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

There are incredibly plenty of details like that take into consideration. That is the fantastic specify raise up. I offer the thoughts above as general inspiration but clearly you can find questions such as the one you raise up where the most critical factor will probably be doing work in honest very good faith. I don?t know if guidelines have emerged about things like that, but More than likely that your particular job is clearly identified as a fair game. Both boys and girls notice the impact of a moment’s pleasure, for the rest of their lives. wps下载电脑版

When I originally commented I clicked the -Notify me when new feedback are added- checkbox and now every time a remark is added I get four emails with the same comment. Is there any approach you’ll be able to remove me from that service? Thanks! wps下载电脑版
