GRAPHICS RENDERING DEVICE

摘要

Graphic form data of a rendering graphic form and a rendering list for defining the specifics of rendering out of an external memory, where the graphic form data and the rendering list are stored in advance, to generate intermediate data and store the intermediate data in the external memory with the use of intermediate data generation means. Intermediate data scanning means detects a graphic form from the intermediate data stored in the external memory. Graphic form rendering means generates pixels of the detected graphic form from the graphic form data stored in the external memory to render an image. The rendering image is written and held in a buffer that has a multi-buffer configuration. Display output means reads the rendering image stored in the buffer and outputs the read rendering image to a display device. The writing in the buffer and the reading out of the buffer are executed alternatingly.

主权项

1. A graphics rendering device configured to render graphics and display the graphics on a screen, comprising:
intermediate data generating means for reading graphic form data of a graphic form to be rendered and a rendering list that defines specifics of rendering, out of an external memory in which the graphic form data and the rendering list are stored in advance, generating intermediate data, and storing the generated intermediate data in the external memory; intermediate data scanning means for detecting a graphic form from the intermediate data stored in the external memory; graphic form rendering means for rendering a rendering image by generating, from the graphic form data stored in the external memory, pixels of the graphic form that has been detected by the intermediate data scanning means; a buffer that has a multi-buffer configuration for holding the rendering image that has been rendered by the graphic form rendering means, in order to execute alternatingly the rendering of a rendering image and the reading of the rendering image that has been rendered; and display output means for outputting a rendering image that is stored in the buffer in order to display the rendering image on a display device.
