US 6,806,875 B2 · Data processing apparatus and shading apparatus

Abstract

In a data processor and a shading apparatus used in the data processor, the data processor selects an address based on the information of a memory or a translation look-aside buffer. Therefore, even when the same data are accessed, a different address at high speed is adopted according to the hardware, object to be processed, processing, etc. A plurality of geometric vectors are given as the parameters for the vertexes of a picture, the vectors are interpolated in the picture, and the luminance of each small area in the figure is calculated using the vectors generated by the interpolation. Therefore, a spotlight or highlight can be expressed with high accuracy and at high speed even when the amount of the hardware and the extent of the picture are small.

Dependent claims

A processing apparatus, comprising:

a memory to store first image data arranged in a tile-type address and second image data arranged in an array-type address;
a first processor to output said tile-type address and to access said first image data stored in said memory;
and
a second processor to output said array-type address and to access said second image data stored in said memory;
wherein said memory, said first processor and said second processor are connected;
and
wherein a memory accessing portion is provided for controlling access from said first processor or said second processor to said memory, and for converting said array-type address output by said second processor into said tile-type address corresponding to said first image data to output to said memory, when said second processor accesses said first image data.
