Dynamic Voltage Scaling for Packet-Based Data Transceivers

The patent applies dynamic voltage scaling to make the transceiver's operating voltage adaptable rather than fixed. The voltage control unit dynamically adjusts the supply voltage based on instantaneous data rate requirements, allowing the system to operate at lower voltages when peak throughput is not needed, thereby reducing power consumption while maintaining the capability to achieve maximum data rate when required.

The invention changes the operating voltage parameter dynamically based on system conditions. By monitoring data rate requirements and adjusting the supply voltage accordingly, the system optimizes the trade-off between productivity and energy consumption. This parameter adaptation allows the transceiver to operate efficiently across different throughput demands rather than being locked into a fixed high-performance configuration.

The patent segments the transceiver into two distinct functional groups: parameter-independent functions and parameter-dependent functions. This segmentation allows different voltage supply strategies to be applied to each group. The parameter-independent functions receive constant voltage for design simplicity, while parameter-dependent functions receive dynamically scaled voltage for power optimization, thus resolving the contradiction between design simplicity and power efficiency.

The invention applies local quality by providing different voltage supply characteristics to different parts of the transceiver based on their specific requirements. Rather than applying a uniform voltage strategy throughout, the system tailors the voltage supply to the local needs of each functional block, giving constant voltage where simplicity is paramount and variable voltage where performance adaptation is needed.

The system dynamically adjusts voltage based on instantaneous data rate requirements rather than operating at a fixed low voltage. When high data rates are needed, the voltage control unit increases the supply voltage to maintain performance. When lower data rates suffice, the voltage is reduced to improve energy efficiency. This dynamic adaptation resolves the contradiction by making performance and efficiency context-dependent rather than mutually exclusive.

The patent implements a feedback mechanism where the voltage control unit monitors system parameters and data rate requirements, then adjusts the supply voltage accordingly. This closed-loop control ensures that voltage is optimized for energy efficiency while automatically maintaining sufficient performance levels, preventing the data rate from deteriorating below acceptable thresholds even when operating at reduced power consumption.
