The present invention provides a processor including a core circuit, a plurality of clock signal generation circuits, a multiplexer and a detection circuit is disclosed. The core circuit is supplied by a supply voltage. The plurality of clock signal generation circuits are configured to generate a plurality of clock signals with different frequencies, respectively, wherein a number of the plurality of clock signals is equal to or greater than three. The multiplexer is configured to receive the plurality of clock signals, and to select one of the plurality of clock signals to serve as an output clock signal according to a control signal, wherein the core circuit uses the output clock signal to serve as an operating clock. The detection circuit is configured to detect a level of the supply voltage received by the core circuit in a real-time manner, to generate the control signal.

Processor with adjustable operating frequency

The present invention discloses an AVS scanning method, wherein the AVS scanning method includes the steps of: mounting a system on chip (SoC) on a printed circuit board (PCB), and connecting the SoC to a storage unit; enabling the SoC to read a boot code from the storage unit, and executing the boot code to perform an AVS scanning operation on the SoC to determine a plurality of target supply voltages respectively corresponding to a plurality of operating frequencies of the SoC to establish an AVS look-up table; and storing the AVS look-up table into the SoC or the storage unit.

Adaptive voltage scaling scanning method and associated electronic device

A control device and a circuit board are provided. The control device can cooperate with the circuit board, and includes a ball grid array. The ball grid array includes a plurality of power balls and a plurality of ground balls, which are jointly arranged in a ball region. The power balls and the ground balls are respectively divided into a plurality of power ball groups and a plurality of ground ball groups. One of the ground ball groups includes two ground balls and is adjacent to a power ball group. A ball pitch between the two ground balls is greater than that between one of the power balls and one of the ground balls adjacent to each other. The circuit board includes a contact pad array corresponding to the ball grid array of the control device so that the control device can be disposed on the circuit board.
