SYSTEM ON CHIP AND SEMICONDUCTOR DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18316697 titled 'SYSTEM ON CHIP AND SEMICONDUCTOR DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a system on chip (SoC) and semiconductor device that includes multiple functional blocks, a frames per second (FPS) meter, a thermal management unit (TMU), a dynamic voltage frequency scaling (DVFS) controller, and a power management unit (PMU).
- The FPS meter measures the FPS based on data processed by the functional blocks.
- The TMU senses the temperature of each functional block.
- The DVFS controller performs DVFS on the functional blocks.
- The PMU independently controls the power of the functional blocks.
- The DVFS controller checks the FPS for the functional blocks when their operating frequency is limited.
- The DVFS controller limits the operating frequency of at least one functional block to a threshold value or less using the FPS and temperature information.
Potential applications of this technology:
- Mobile devices: The SoC and semiconductor device can be used in mobile devices such as smartphones and tablets to optimize power consumption and performance based on FPS and temperature measurements.
- Gaming consoles: The technology can be applied in gaming consoles to manage power and performance of different functional blocks based on FPS and temperature data.
Problems solved by this technology:
- Power optimization: The DVFS controller and PMU allow for independent control of power consumption in different functional blocks, optimizing power usage based on FPS and temperature measurements.
- Thermal management: The TMU senses the temperature of each functional block, allowing for effective thermal management and preventing overheating.
Benefits of this technology:
- Improved performance: By dynamically adjusting the operating frequency of functional blocks based on FPS and temperature, the system can optimize performance and prevent performance degradation.
- Power efficiency: The independent power control of functional blocks helps in reducing power consumption and increasing overall power efficiency.
- Thermal protection: The TMU ensures that the temperature of functional blocks is monitored and controlled, preventing overheating and potential damage to the device.
Original Abstract Submitted
A system on chip and semiconductor device including the same are provided. The system on chip comprises a plurality of functional blocks, a frames per second (FPS) meter measuring FPS based on data processed by the functional blocks, a thermal management unit (TMU) sensing a temperature of each of the functional blocks, a dynamic voltage frequency scaling (DVFS) controller performing DVFS on the functional blocks, and a power management unit (PMU) independently controlling the power of the functional blocks, wherein the DVFS controller checks the FPS for the functional blocks when an operating frequency of each of the functional blocks is limited and limits the operating frequency of the at least one of the functional blocks to a threshold value or less using the FPS checked by the DVFS controller and the temperature of each of the functional blocks.
