Abstract: A bus architecture and a data transmission method thereof are applicable to a signal transmission environment between functioning components of an information system, so as to transmit data, addresses and/or control signals between any two of the functioning components of the information system in a serial transmission manner via at least one wire. During the data transmission method, the bus architecture can convert a parallel signal to a serial signal and/or convert a serial signal to a parallel signal, and the sequence of the two conversions being performed or the proceeding of only one or both of the conversions depends on practical requirements.

Abstract: A graphics rendering system and a graphics rendering method are applied in an environment for graph production and image processing. After a graph code is entered into the graphics rendering system, it is analyzed by a graph code processing module in the graphics rendering system to find one or more records of data corresponding to the graph code and transfer the one or more records of data to an image producing module, wherein the data are in the command form and required for outputting complete graphs/images. The image producing module includes an image producing program for interpreting and executing the commands. The image producing program decodes composition, structure and ratio of graphs/images from the graph code and produces the required graphs/images according to graph/image producing parameters obtained from information provided by the data corresponding to the graph code, without having to use lookup table mapping in the prior art.
