This section details the registers available in the DisplayPort 1.4 RX Subsystem. The address map is split into the following regions:
  • DisplayPort RX IP
  • AXI IIC
  • HDCP Controller
  • AXI Timer

The address offsets of the helper cores is shown in the following table.

Table 1. RX Subsystem Helper Core Address Offsets
Helper Core Address Space Address Offset
DisplayPort 8K 0x0000_0000
AXI IIC 4K 0x0000_2000
AXI Timer 4K 0x0000_3000
HDCP 1.x Subsystem 4K 0x0000_4000
Clocking Wizard 4K 0x0000_5000
HDCP 2.x Subsystem 16K 0x0000_8000
The subsystem address propagation in the Vivado® IP integrator assigns the maximum addresses based on full-featured configuration. Ensure the following steps are taken:
  1. Confirm that the DisplayPort 1.4 RX Subsystem IP is mapped to a base address where the 14th bit in the address is 0. For example, 0x44A00000 is correct and 0x44A02000 causes errors.
  2. Ensure that all 14 bits of the address range are reserved for the DisplayPort 1.4 RX Subsystem IP.
