Processor Clock Speed Adjustment via External Temperature Sensor

The patent implements dynamic clock speed adjustment by introducing a clock governor that continuously monitors execution state and temperature, then adaptively selects from multiple clock speed levels. This transforms the static clock speed into a dynamic parameter that changes based on real-time conditions, resolving the contradiction between maintaining high performance and reducing energy consumption during different execution phases.

The patent changes the operational parameters of the processor by introducing multiple clock speed levels (first clock speed, second clock speed lower than the first) and selectively switching between them based on execution state and temperature conditions. This parameter change allows the system to optimize the balance between performance and energy consumption by using high clock speeds only when necessary and low clock speeds when the application can tolerate reduced performance.

The patent implements a feedback mechanism where the temperature sensor continuously monitors the execution state and temperature of the electronic device, and this information is fed back to the clock governor. The clock governor uses this feedback to dynamically adjust the clock speed, reducing it when temperature exceeds thresholds. This closed-loop feedback system resolves the contradiction by automatically responding to heat generation and adjusting performance levels accordingly.

The patent makes the clock speed dynamic by introducing real-time temperature monitoring and adaptive adjustment mechanisms. The system transitions from a fixed high clock speed to a dynamic clock speed that responds to thermal conditions, allowing performance to be optimized without causing excessive heat generation that would compromise device stability.

The patent creates a universal clock governor mechanism that serves multiple functions: it manages clock speeds for different applications, monitors temperature conditions, and adapts execution policies based on environmental factors. This multi-functional component resolves the contradiction by integrating both application-specific optimization and environmental adaptability into a single coordinated system that considers both performance requirements and thermal conditions.

The clock governor acts as an intermediary between the application execution system and the hardware resources (processor, temperature sensor). It receives execution state information from applications and temperature data from sensors, then mediates the selection of appropriate clock speeds by considering both application performance requirements and environmental conditions. This intermediary layer enables the system to balance performance optimization with environmental adaptability.
