Abstract: A method and circuitry for generating a trigger signal based on an oscillation signal and associated non-transitory computer program product are provided. The method includes following steps. Firstly, a calibration value is obtained according to a reference frequency and a frequency of the oscillation signal, and a counting value is gradually altered from a first initial value to a breakpoint value. Secondly, the counting value is updated to a second initial value when the counting value is equal to the breakpoint value. Then, the counting value is gradually altered from the second initial value to a final value, and the trigger signal is generated when the counting value is equal to the final value.

Abstract: A media peripheral interface for communication between a processor and a peripheral device includes a clock port, a plurality of data I/Os, and a data strobe port. The clock port is operative to transfer a clock signal to the peripheral device. The data I/Os are provided for command transfer to the peripheral device and for data transfer to and from the peripheral device. The data strobe port is operative to transfer a data strobe signal to or from the peripheral device according to an instruction that the processor issues to the peripheral device. According to the clock signal, command information transferred via the data I/Os is captured. According to rising edges and falling edges of the data strobe signal, data transferred via the data I/Os are captured.
