    • A system for accessing texture data in a graphics rendering system allows texture data to be stored in memories with high latency or in a compressed format. The system utilizes a texture cache to temporarily store blocks of texture data retrieved from an external memory during rendering operations. In one implementation, geometric primitives are stored in a queue long enough to absorb the latency of fetching and possibly decompressing a texture block. The geometric primitives are converted into texture block references, and these references are used to fetch texture blocks from memory. A rasterizer rasterizes each geometric primitives as the necessary texture data becomes available in the texture cache. In another implementation, geometric primitives are converted into pixels, including a pixel address, color data, and a texture request. These pixels are stored in a queue long enough to absorb the latency of a texture block fetch. The texture requests are read from the queue and used to fetch the appropriate texture blocks. As texture data becomes available in the texture cache, the texture data is sampled as necessary and combined with the pixel data read from the queue to compute output pixels.
    • 用于在图形渲染系统中访问纹理数据的系统允许纹理数据以高延迟或压缩格式存储在存储器中。 该系统利用纹理缓存临时存储在渲染操作期间从外部存储器检索的纹理数据块。 在一个实现中,几何基元被存储在队列中足够长的时间以吸收提取的延迟并且可能解压缩纹理块。 几何基元被转换为纹理块引用,这些引用用于从内存中获取纹理块。 当纹理缓存中必需的纹理数据变得可用时,光栅化器会栅格化每个几何图元。 在另一个实现中,几何基元被转换成像素,包括像素地址,颜色数据和纹理请求。 这些像素被存储在足够长的队列中以吸收纹理块提取的等待时间。 从队列中读取纹理请求,并用于获取适当的纹理块。 随着纹理数据在纹理高速缓存中变得可用,纹理数据根据需要进行采样,并与从队列读取的像素数据组合以计算输出像素。

    • A system for managing space in a computer memory is disclosed. The system creates free space in a computer memory by using a “downsize” operation, which selectively removes data from a data object residing in the memory. Each data object in the memory provides a downsize operation designed for that data object, which reduces the amount of space that the data object occupies in the memory by deleting data that can be recreated from another source, or data that is not essential to the function of the data object. Each data object may also provide a “restore” operation, which returns the object to a usable state in the memory by replacing data in the memory that has been removed by a prior downsize operation. The restore operation is used if an attempt is made to access the data object after it has been downsized. The system can be used to manage various types of memory containing various types of data objects. One use of the system is to manage the space on a personal computer hard disk by downsizing applications on the disk when additional disk space is needed and then restoring a downsized application when a user attempts to run it. Another use of the system could include management of a database on a storage medium by deleting portions of the database that have been archived on another medium and retrieving portions from the archive on an as-needed basis.
    • 公开了一种用于管理计算机存储器中的空间的系统。 系统通过使用“缩小”操作在计算机存储器中创建可用空间,该操作有选择地从驻留在存储器中的数据对象中删除数据。 内存中的每个数据对象都提供了一个为该数据对象设计的小型化操作,通过删除可从另一个源重新创建的数据,或减少对该函数不是必需的数据,减少了数据对象在内存中占用的空间量 的数据对象。 每个数据对象还可以提供“还原”操作,其通过替换由先前的小型化操作去除的存储器中的数据将对象返回到存储器中的可用状态。 如果在数据对象缩小之后尝试访问数据对象,则使用还原操作。 该系统可用于管理包含各种类型的数据对象的各种类型的存储器。 该系统的一个用途是通过在需要额外的磁盘空间时缩小磁盘上的应用程序,然后在用户尝试运行时恢复缩小的应用程序,来管理个人计算机硬盘上的空间。 该系统的另一用途可以包括通过删除已经存档在另一介质上的数据库部分,并根据需要从存档中检索部分来管理存储介质上的数据库。
