This section describes the integration of the display subsystem module in the device, including information about clocks, resets, and hardware requests.
Figure 11-3 shows the integration of the display subsystem in the device.

DMA Requests | ||||
Module Instance | Source Signal Name | Destination DMA_CROSSBAR Input | Default Mapping | Description |
DISPC | DISPC_DREQ | DMA_CROSSBAR_6 | DMA_EDMA_DREQ_5 | The line trigger signal to synchronize a memory-to-memory logical channel in the DMA is generated by the DISPC IP. |

HDMI | DSS_DREQ | DMA_CROSSBAR_76 | DMA_SYSTEM_DREQ_75 | Display subsystem HDMI audio DMA request |
The “Default Mapping” column in Table 11-5
Display Subsystem Hardware Requests shows the default mapping of module
IRQ and DREQ source signals. These module IRQ and DREQ source signals can also
be mapped to other lines of each device Interrupt or DMA controller through the
IRQ_CROSSBAR and DMA_CROSSBAR modules, respectively.
For more information about the IRQ_CROSSBAR module, see IRQ_CROSSBAR
Module Functional Description, in Control Module.

module, see DMA_CROSSBAR Module Functional Description, in Control
Module.
