Title for Topic

This diagram illustrates the flow of data among the L1 data caches and the SCU. The ACP gets data directly from the L1 cache and the read is interleaved with a processor access to the L1 cache.

All other products or services mentioned. Usage constraints This register is writable: Our objectives More information.

Cortex-A9 MPCore

This feature works only if the L2C is present in the design. It does not duplicate information from these sources ARM architecture The Cortex-A9 processor implements the ARMv7-A architecture profile that includes the following architecture extensions: Memory regions used for these registers must be marked as Device or Strongly-ordered in the translation tables.

An explanation with as much information as you can provide.

The top of the region is determined by the L2 cache filter. Attributes See the register summary in SCU registers summary on page Reference to a feature that is included means that the appropriate build and pin configuration options techniacl selected.

Related Information System Interconnect. You can enter the underlined text instead of the full command or option name.

The floating-point unit FPU can execute half- single- and double-precision variants of the following operations: This might include integrating RAMs into the design. With the exception of a few debug configuration signals, the debug interfaces of the individual Cortex-A9 processors are presented externally so that each referrence can be debugged independently. ARM11 performance monitor unit.

To be kept coherent, the memory must be marked as Write-Back, Shareable, Normal memory. Includes support for floating-point operations.

Course responsible and examiner: The preload functionality is under software control. For information on the relevant technica standards and protocols, see Compliance on page Documentation Design flow The Cortex-A9 MPCore documentation is manjal follows: To use the ACP for coherent accesses, the following configurations apply: It contains the following sections: See About the Global Timer on page All transactions that are set as cacheable are routed to the ACP instead of the normal mapping and are treated as coherent by the cache controllers of the MPU subsystem.

The encoding is as follows: The preload engine PLE is a hardware block that enables the L2 cache to preload selected regions of memory.

The cache control is done cortxe-a9 by the. Freescale Semiconductor Document Number: Up to 24 per processor. The PMU supports 58 events to gather statistics on the operation of the processor and memory system.
