OpenMAX, etc.)
+It is important to note that these blocks can interact with each other. The
+picture below illustrates some of the components and their interconnection:
+
+.. kernel-figure:: amd_overview_block.svg
+
+In the diagram, memory-related blocks are represented by a green color. Notice
+that specific IPs have a green block that represents a small hardware block
+named 'hub', which is responsible for interfacing with memory (pre-vega devices
+have a dedicated block for that, named GMC). In the driver code, you can
+identify this component by looking for the suffix hub, for example: gfxhub,
+dchub, mmhub, vmhub, etc. All memory hubs are connected in the UMC, which in
+turn is connected to memory blocks.
+
+There is some level of protection for certain elements in memory, and the PSP
+plays an essential role in this area. For example, when a specific firmware is
+loaded into the memory, PSP takes an action to ensure that the firmware has a
+valid signature. Another use of PSP is to support the TA (e.g., HDCP) and
+encrypted memory via TMZ.
+
+Another IP that deserves attention is the SMU, as it is connected to all the
+other IPs. SMU will help put the GPU in optimal utilization by taking into
+account performance and power consumption. SMU helps other blocks to set up a
+proper clock configuration. Another feature of SMU is the support for resetting
+every component.
