This section describes the system MMUs integration in the device, including information about clocks, resets, and hardware requests. For more information about DSP, EVE, and IPU MMUs integration, refer to their respective chapters.
Figure 22-3 and Figure 22-4 show system MMU1, and MMU2 integration, respectively.
Table 22-1 through Table 22-3 summarize the system MMUs integration.
Module Instance | Attributes | |
Power Domain | Interconnect | |
System MMU1 | PD_COREAON | L4_PER3 |
System MMU2 | PD_COREAON | L4_PER3 |
Clocks | ||||
Module Instance | Destination Signal Name | Source Signal Name | Source | Description |
System MMU1 | MMU1_CLK | L3MAIN1_L3_GICLK | PRCM | System MMU1 interface/functional clock. This clock is used for all interface and functional operations. |
System MMU2 | MMU2_CLK | L3MAIN1_L3_GICLK | PRCM | System MMU2 interface/functional clock. This clock is used for all interface and functional operations. |
Resets | ||||
Module Instance | Destination Signal Name | Source Signal Name | Source | Description |
System MMU1 | MMU1_RST | CORE_RET_RST | PRCM | System MMU1 hardware reset. This reset is asynchronously applied to the MMU1 internal registers. |
System MMU2 | MMU2_RST | CORE_RET_RST | PRCM | System MMU2 hardware reset. This reset is asynchronously applied to the MMU2 internal registers. |
Interrupt Requests | ||||
Module Instance | Interrupt Name (Source) | IRQ_CROSSBAR Input (Destination) | Default Mapping | Description |
System MMU1 | MMU1_IRQ | IRQ_CROSSBAR_333 | – | System MMU1 interrupt. |
System MMU2 | MMU2_IRQ | IRQ_CROSSBAR_369 | – | System MMU2 interrupt. |
No DMA Requests |
