    • A data conversion apparatus for converting index data to real data and an image generation apparatus for converting index texture data to real texture data by the data conversion to make it possible to suitably carry out texture mapping. A data conversion apparatus comprises a first memory and a second memory each for storing data having a n bit width and in which any data is stored, an address detecting means for detecting addresses of the first memory and the second memory based on input data, a data reading means for reading data stored at the detected addresses of the first memory and the second memory, a first data selecting means for selecting either of the data read from the first memory or the data read from the second memory, a data extending means for extending the selected data to data having a 2×n bits width, and a second data selecting means for selecting either of the first data formed by connecting the data output from the first memory and the data output from the second memory or the second data of the extended data.

    • A system for mapping texture data at high speed with flexibility to different applications wherein texture data is sent to a memory interface (MEMIF) thorough a digital differential analyzer (DDA) and a texture mapping unit (TMAP) and loaded to free areas of a Z coordinatory memory (ZBUF) and a drawing data memory (FBUF). A Z coordinate value or drawing data is read/written through a bidirectional port. The TMAP converts texture coordinates into a physical address, reads texture data from dedicated read ports of the ZBUF and the FBUF with the physical address, and maps the texture data. Each of the ZBUF and the FBUF has a DRAM unit and an auxiliary memory. Data of one row of the DRAM unit can be sent to the auxiliary memory means at a time. When desired texture data is not present in the auxiliary memory, data of the entire row of the desired texture data is sent to the auxiliary memory and then read.
    • 一种用于将纹理数据高速映射到不同应用的系统,其中纹理数据通过数字差分分析器(DDA)和纹理映射单元(TMAP)发送到存储器接口(MEMIF),并被加载到Z的空闲区域 协调记忆体(ZBUF)和图形数据存储器(FBUF)。 通过双向端口读/写Z坐标值或绘图数据。 TMAP将纹理坐标转换为物理地址,从物理地址的ZBUF和FBUF的专用读取端口读取纹理数据,并映射纹理数据。 每个ZBUF和FBUF都有一个DRAM单元和一个辅助存储器。 DRAM单元的一行的数据可以一次发送到辅助存储装置。 当期望的纹理数据不存在于辅助存储器中时,期望纹理数据的整行的数据被发送到辅助存储器然后读取。
