4.3 ARMCortexA9MPxnCT
Figure 4-2 shows a view of the ARMCortexA9MPxnCT component in Fast Models, with all
vectored ports collapsed. This is a single component that represents a Cortex-A9 multiprocessor
containing from one to four processors. The xn in the component name indicates how many
processors are included in the component, so choose the one with the required number of
processors for your system. The component is based on r1p0 of the Cortex-A9 processor. All
variants of the ARMCortexA9MPxnCT component are described in this section, the only
difference being the number of processors.
The ARMCortexA9MPxnCT component implements the following additional peripherals, that
are not present in the basic Cortex-A9 processor:
• Snoop Control Unit (SCU)
• Generic Interrupt Controller (GIC)
• private timer and watchdog for each processor
• global timer
• Advanced Coherency Port (ACP).
These embedded peripherals are more fully documented elsewhere. See the processor technical
reference manual.
This component is written in C++.
