Systems and Methods for Reducing Power at System-On-Chip

Patent number 9026828, filed on December 31, 2012, and published online on May 5, 2015, proposes innovative systems and methods for reducing power consumption at system-on-chip. The invention, attributed to inventor Park, Jinkwon, focuses on optimizing power management in low-power systems, addressing the increasing need for energy conservation in home appliances and office equipment. This breakthrough incorporates low-power techniques, such as static and dynamic power consumption reduction, to minimize power consumption while maintaining operational efficiency.

Key Takeaways:

  • The patent, titled "Systems and Methods for Reducing Power at System-On-Chip," presents an inventive concept that includes a power-off domain block and a power-on domain block.
  • The power-off domain block receives power in response to the wake-up operation and comprises a main CPU, a memory controller, and various intellectual properties that perform individual functions.
  • The power-on domain block analyzes externally transferred data during a power-down state of the power-off domain block and substitutes an operation of the power-off domain block based on the analyzed result.
  • The inventive concept encompasses various aspects, including the power-off domain block being powered down in a power-save mode and the low-power management module performing an operation of the main CPU during the power-down state.
  • The wake-up intellectual property analyzes data, and the keep-alive intellectual property activates power of the power-off domain block according to the result analyzed by the wake-up intellectual property.
  • The system-on-chip also includes a power-on domain block with a low-power CPU and a memory that serves as an auxiliary memory of the power-off domain block at a power-on mode and as a memory storing programs and data for the low-power CPU at a power-off mode.
  • The power-on domain block analyzes externally transferred data during a power-down state of the power-off domain block to substituted an operation of the power-off domain block, based on the analyzed result.
  • When the system-on-chip satisfies a power-down condition, programs and data to be used by the low-power CPU are copied to the memory of the power-on domain block, the power-off domain block is powered down, and the low-power CPU is booted up.
