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

Construction Supervisors are very important people when it comes to completing any construction project. They are responsible for supervising and coordinating the activities of all construction workers. Their main job is to examine and inspect all work in progress to make sure that specifications are met and that the construction site itself conforms to established health and safety standards, as well as make sure that projects are completed on time and within the allocated budget. link alternatif dominobet

Over the years, the Chinese construction machinery in the huge domestic demand to promote development and growth, many large and small engineering machinery enterprises own entertainment in the massive Chinese market, enjoying the feast. Meanwhile, foreign counterparts from around the world have also rushed to join the ranks of sub-cake. For a time, the Chinese school of earth rejoice. dominobet
