9.2. Power Management System Integration

The diagram below shows high-level connectivity to the power manager in HPS.

Figure 281. Power Manager Block Diagram

The power manager includes the following blocks:

  • Generic P-channel FSM to implement Arm-based P-channel spec. This is primarily used to manage the power down sequences for DSU cluster (CPU cores and L3 cache).
  • Hardware FSM to implement DSU and CPU core power-off scenarios and associated control, status registers.
  • Power-related control and status registers to support all power gating scenarios.
