Dynamic CPU Frequency Control for Network Packet Processing

The patent applies dynamics by making the CPU activation period variable rather than fixed. The control unit dynamically adjusts the activation period of the main CPU based on the type of network packet received. For high-priority packets requiring immediate attention, the activation period is shortened, allowing faster response. For low-priority packets, the activation period remains longer, maintaining power savings. This dynamic adjustment resolves the contradiction between power consumption and response time.

The patent applies local quality by differentiating the activation period based on the specific type of network packet. Instead of using a uniform activation period for all packets, the control unit identifies the packet type and assigns appropriate activation periods tailored to each packet's requirements. High-priority packets receive shorter activation periods for immediate processing, while low-priority packets use longer periods. This localized differentiation ensures packet response completeness without excessive complexity.

The patent applies parameter changes by dynamically adjusting the clock frequency of the main CPU based on packet priority and activation period requirements. For high-priority packets requiring immediate attention, the CPU operates at highest clock frequency to ensure fast processing. For low-priority packets where timing is less critical, the CPU operates at lower frequencies, reducing power consumption. This parameter adjustment resolves the contradiction between processing speed and power consumption.
