摘要： A vertex processing device applied in an image processing system having an image capture module is disclosed. The image capture module generates camera images. The vertex processing device comprises a coefficient interpolation unit and a coordinate modifying unit. The coefficient interpolation unit generates an interpolated warping coefficient for each camera image with respect to each vertex from a vertex list based on n number of warping coefficients and its original texture coordinates in each camera image. The coordinate modifying unit calculates modified texture coordinates in each camera image for each vertex according to the interpolated warping coefficient and its original texture coordinates in each camera image. The vertex list comprises vertices with data structures that define vertex mapping between the camera images and a panoramic image. The n number of warping coefficients correspond to n number of overlap regions in the panoramic image.

摘要： A System on Chip (SOC) is disclosed. The SOC comprises a first UART controller, a second UART controller, a debug controller, a processor, a UART port, a first multiplexer and a second multiplexer. The first UART controller and the second UART controller have different baud rates. The UART port has a R×D pin coupled to a R×D pin of the second UART controller. The debug controller generates a control signal with a first state and checks whether a received data from the UART controller is equal to a keyword after power-up or a hardware reset. When the received data from the second UART controller is equal to the keyword, the debug controller generates the control signal with the second state, and starts parsing and executing at least one debug command from the second UART controller.
