Abstract: A detection circuit is provided in the invention. The detection circuit includes a synchronous circuit, a comparison circuit and a fail-signal generating circuit. The comparison circuit is coupled to the synchronous circuit. The comparison circuit compares a target signal with a reference signal to generate a comparison result. The frequency of the reference signal is lower than the frequency of the target signal. The fail-signal generates circuit is coupled to the synchronous circuit and the comparison circuit. The fail-signal receives the comparison circuit. According to the comparison circuit, the fail-signal determines whether the target signal has failed.

Abstract: A device and method for blending image data and the alpha channel and reconstructing to obtain the image again after transmission. An encoder blends the alpha channel and the red-green-blue (RGB) image data through a layer blending method that is supported by the general application processor (AP). Transporter image data, such as a checkerboard pattern, is blended with 1-alpha channel data to obtain a transporter. The blended image data (RGB+alpha) is mixed with the transporter to obtain mixed image data. The mixed image data is then transmitted through the existing transmission interface. After receiving the mixed image data, reconstruction processing is performed by a decoder to obtain the original RGB image data and the alpha channel again.

Abstract: A clock multiplier is provided. The clock multiplier includes a delay line, an output clock generator, and a delay controller. The delay line receives an input clock and delays the input clock according to a selection signal group with multiple bits to provide a plurality of delayed clocks and a feedback clock. The output clock generator performs a logic operation on the input clock and a portion of the delayed clocks to generate an output clock. A frequency of the output clock is an integer multiple of a frequency of the input clock. The delay controller adjusts the selection signal group according to a timing difference between the input clock and the feedback clock, so that a transition point of the feedback clock approaches a transition point of the input clock.
