Abstract: A neural network based method places flexible blocks on a chip canvas in an integrated circuit (IC) design. The neural network receives an input describing geometric features of a flexible block to be placed on the chip canvas. The geometric features includes an area size and multiple aspect ratios. The neural network generates a probability distribution over locations on the chip canvas and the aspect ratios of the flexible block. Based on the probability distribution, a location on the chip canvas is selected for placing the flexible block with a chosen aspect ratio.

Abstract: A word boundary detection method includes receiving a data stream from a data channel of a high definition multimedia interface (HDMI), and performing pattern matching upon the data stream to identify a word boundary between two consecutive codewords transmitted via the data stream. Known codewords of scrambled control vectors are involved in the pattern matching.

Abstract: A neural network is used to place macros on a chip canvas in an integrated circuit (IC) design. The macros are first clustered into multiple macro clusters. Then the neural network generates a probability distribution over locations on a grid and aspect ratios of a macro cluster. The grid represents the chip canvas and is formed by rows and columns of grid cells. The macro cluster is described by at least an area size, aspect ratios, and wire connections. Action masks are generated for respective ones of the aspect ratios to block out a subset of unoccupied grid cells based on design rules that optimize macro placement. Then, by applying the action masks on the probability distribution, a masked probability distribution is generated. Based on the masked probability distribution, a location on the grid is selected for placing the macro cluster with a chosen aspect ratio.

Abstract: A channel hiatus correction method for an HDMI device is provided. A recovery code from scrambled data of the stream is obtained. A liner feedback shift register (LFSR) value of channels of the HDMI port is obtained based on the recovery code and the scrambled data of the stream. The stream is de-scrambled according to the LFSR value of the channels of the HDMI port. Video data is displayed according to the de-scrambled stream.

Abstract: A power-saving method for switching High Definition Multimedia Interface (HDMI) ports on a sink device is provided. The sink device has a first HDMI port initially being enabled for displaying and a second HDMI port being disabled for displaying. The power-saving method includes the steps of using the reference signals to locate the VSYNC active edge in each frame generated by a source device connected to the second HDMI port; turning on the power to the second HDMI port during a power-on region corresponding to the VSYNC active edge in each frame and turning off power otherwise; obtaining information related to a high bandwidth digital content protection (HDCP) in the power-on region; and displaying video data from the source device based on the HDCP information when enabling the second HDMI port connected to the source device.
