System on a Chip that Drives Display when CPUs are Powered Down - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240094797 titled 'System on a Chip that Drives Display when CPUs are Powered Down
Simplified Explanation
The patent application describes a system with processors, a display controller, a memory controller, and a power management circuit that can establish different power states. In one power state, the display controller and memory controller are powered on while the CPUs are powered off, allowing the display controller to read and display prerendered frames from memory.
- System includes processors, display controller, memory controller, and power management circuit
- Power management circuit can establish different power states
- Display controller can read and display prerendered frames from memory
- CPUs are powered off in one power state
