This section describes the integration of the module in the device, including information about clocks, resets, and hardware requests.
Figure 14-2 shows the GPU integration.
Figure 14-2 GPU IntegrationThe GPU subsystem is connected to the level 3 (L3_MAIN) interconnect by two 128-bit master and a 64-bit slave interfaces.
Table 14-1 through Table 14-3 summarize the integration of the module in the device.

The “Default Mapping” column in Table 14-3, GPU Hardware Requests shows the default mapping of module IRQ source signals. These IRQ source signals can also be mapped to other lines of each device Interrupt controller through the IRQ_CROSSBAR module.
For more information about the IRQ_CROSSBAR module, see Section 20.4.6.4, IRQ_CROSSBAR Module Functional Description, in Chapter 20, Control Module.
For more information about the device interrupt controllers, see Chapter 19, Interrupt Controllers.
No DMA and no wake-up requests are generated by the GPU subsystem.
