摘要： An embodiment of a processing device includes a function unit and a control unit. The function unit receives input data and performs a specific operation to the input data to generate result data. The control unit receives the result data and generates an output signal. The control unit latches the result data according to a first clock signal to generate first data and latches the result data according to a second clock signal to generate second data. The control unit compares the first data with the second data to generate a control signal and selects the first data or the second data to serve as data of the output signal according to the control signal. The second clock signal is delayed from the first clock signal by a predefined time period.

摘要： A voltage scaling system is provided and includes a processor, a latency predictor, a controller, and a voltage supplier. The processor performs functions and includes a function unit with variable-latency. The function unit is divided into several power domains. When the processor performs the functions, the function unit generates a latency signal according to a current circuit execution speed. The latency predictor predicts performance of the processor according to the received latency signal to generate a predication signal. The controller compares a value of the predication signal with at least one reference value. The controller generates control signals according to the comparison result. The voltage supplier couples to a first voltage source providing a high voltage and a second voltage source providing a low voltage. The voltage supplier is switched to provide the high or low voltage to the power domains according to the control signals, respectively.
