Problems solved by technology

Therefore, the size of the control list that can be processed is limited by the amount of memory available to the software
Known software algorithms therefore have the disadvantage that a large amount of storage space is required to store all commands of a complex polygon prior to rendering
[0018] However, for more complex polygons, triangulation is not easy, especially for those that intersect themselves, because the entire complex polygon must be input and stored before triangulation to avoid filling in pixels that will later become "holes"

example 1

[0334] Example 1: Full screen Chinese text (static)

[0335] A complex situation is represented, yielding 42240 pixels or 84480 bytes for a display size of 176x240 (16 bits / pixel = 2 bytes / pixel). Assuming that a Chinese character is a minimum of 16×16 pixels, this realizes 165 Chinese characters per screen. A Chinese character is described by about 223 bytes on average, resulting in a total data volume of 36855 bytes.

Abstract

The invention provides a graphics engine for rendering image data for display pixels in dependence upon received high-level graphics commands defining polygons including an edge draw unit to read in a command phrase of the language corresponding to a single polygon edge and convert the command to a spatial representation of the edge based on that command phrase. An electrical device incorporating the graphics engine and a memory integrated circuit having an embedded graphics engine are also provided.

Description

technical field [0001] The present invention relates to a graphics engine, an electronic device and a memory incorporating the graphics engine. Background technique [0002] The present invention applies to displays of electronic devices, especially small area displays on portable or console electronic devices. There are many such devices such as PDAs, cordless phones, mobile and desk phones, information dashboards in automobiles, handheld electronic game devices, multifunction watches, and the like. [0003] In the prior art, there is usually a main CPU that generates commands, receives display commands, processes these display commands, and transmits the processing results to the display module in the form of pixel data describing the properties of each display pixel. The amount of data sent to the display module is directly proportional to the display resolution and color depth. For example, a small monochrome display of 96x96 pixels with four levels of gray requires a ...
