This section describes the integration of the module in the device, including information about clocks, resets, and hardware requests. Figure 10-1 summarizes the integration of the module in the device.
Alternative clocking to the VPE module is provided from DPLL_VIDEO1. For more information about configuring DPLL_VIDEO1, see Section 11.1.2.1, Display Subsystem Clocks. Source clock selection is done with CTRL_CORE_SMA_SW_1[8] VPE_CLK_DIV_BY_2_EN register from the Control Module. For more information, see Control Module.
Table 10-1 and Table 10-2 list the integration attributes and clock and resets, respectively.

Clocks | ||||
---|---|---|---|---|
Module Instance | Destination Signal Name | Source Signal Name | Source | Description |
VPE | L3_CLK PROC_CLK | VPE_GCLK | PRCM | L3_CLK is the clock used to drive and receive data over the bus to L3_MAIN. The VPDMA uses this clock to send and receive external data and transfer this data to internal processing. PROC_CLK is the clock used to drive data processing within the VPE subsystem. |
L4_CLK PROC_D2_CLK | VPE_GCLK/2 | PRCM | L4_CLK is the interface clock for Memory Mapped Registers (MMR) configuration bus PROC_D2_CLK is an additional clock used by the DEI within the DEI Subsystem. Inputs and outputs of the DEI operate on PROC_CLK, but internally, the data paths within the DEI operate on this clock. | |

Module Instance | Destination Signal Name | Source Signal Name | Source | Description |
VPE | VPE_RST | VPE_RST | PRCM | VPE Reset |
Interrupt Requests | ||||
Module Instance | Source Signal Name | Destination IRQ_CROSSBAR Input | Default Mapping | Description |
VPE | VPE_IRQ | IRQ_CROSSBAR_354 | N/A | VPE interrupt requests. These IRQ source signals are not mapped by default to any device INTC. |
The “Default Mapping” column in Table 10-3
VPE Hardware Requests shows the default
mapping of module IRQ source signals. These module
IRQ source signals can also be mapped to other
lines of each device Interrupt controller through
the IRQ_CROSSBAR module, respectively.

controllers, see Interrupt Controllers.
