11. Clock Manager
The hard processor system (HPS) clock generation is centralized in the clock manager. The clock manager is responsible for providing software-programmable clock control to configure all clocks generated in the HPS. Clocks are organized in clock groups. A clock group is a set of clock signals that originate from the same clock source which may be synchronous to each other. The Clock Manager has two phase-locked loop (PLL) clock group where the clock source is a common PLL voltage-controlled oscillator (VCO). A clock group which is independent and asynchronous to other clocks may only have single clock, also known as clock slice. Peripheral clocks are a group of independent clock slices.
