1.1. About the Cortex-A9 MPCore processor

The Cortex-A9 MPCore processor consists of:

Individual Cortex-A9 processors in the Cortex-A9 MPCore cluster can be implemented with their own hardware configurations. See the Cortex-A9 Technical Reference Manual for additional information on possible Cortex-A9 processor configurations. ARM recommends you implement uniform configurations for software ease of use.

There are other configuration options that impact Cortex-A9 MPCore system integration. The major options are:

See Configurable options.

Figure 1.1 shows an example multiprocessor configuration.

It is possible to implement only one Cortex-A9 processor in a Cortex-A9 MPCore processor design. In this configuration, an SCU is still provided. The ACP, and an additional master port, are still available as configuration options.
