A transform, lighting and rasterization system embodied on a single semiconductor platform

(57) Graphics operation is provided with a summary graphic pipe-line system. The conversion module 52 contained in such a system is constituted so that it may be combined with the peak attribute buffer 5, in order to receive peak data. The conversion module 52 performs the duty which changes peak data into screen space from an object space. The writing module 54 is combined with a conversion module, and this is located in one semiconductor platform in order to perform writing operation by the peak data received from the conversion module. Moreover, it is combined with the writing module 54, and in order to carry out the rendering of the peak data received from there, the rasterization equipment located in one semiconductor platform is also contained.
