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
