摘要： A tracking buffer apparatus is disclosed. A tracking buffer apparatus includes lookup logic configured to locate entries having a transaction identifier corresponding to a received request. The lookup logic is configured to determine which of the entries having the same transaction identifier has a highest priority and thus cause a corresponding entry from a data buffer to be provided. When information is written into the tracking buffer, write logic writes a corresponding transaction identifier to the first free entry. The write logic also writes priority information in the entry based on other entries having the same transaction identifier. The entry currently being written may be assigned a lower priority than all other entries having the same transaction identifier. The priority information for entries having a common transaction identifier with one currently being read are updated responsive to the read operation.

摘要： A write buffer for read-write interlocks improves memory access performance by minimizing the latency needed to avoid a read-after-write hazard when a read follows a write to the same memory location. Rather than waiting until a write has been stored in the memory location, the write buffer provides an acknowledgement signal before the data has been stored in memory in order for a subsequent read of the memory location to proceed. The write buffer merges the data to be written with any data that is stored in memory for the read request to return the current data for the read request.
摘要翻译：用于读写互锁的写缓冲器通过最小化在读写到同一存储单元时避免读写后危险所需的延迟来提高存储器访问性能。写缓冲器不是等待写入已经存储在存储器位置中，而是在数据已经存储在存储器中之前提供确认信号，以便继续读取存储器位置。写入缓冲区将要写入的数据与存储在读取请求的存储器中的任何数据合并，以返回读取请求的当前数据。

摘要： Systems and methods for determining the number of texture samples used to produce an anisotropically filtered texture mapped pixel may improve texture mapping performance or image quality. The number of texture samples may be increased or decreased based on texture state variables that may be specific to each texture map. Furthermore, the texture samples may be positioned along an axis of anisotropy to approximate an elliptical footprint, ensuring that the texture samples span the entire axis of anisotropy. A graphics driver may load the texture state variables and configure a system to modify the number of texture samples and/or position the texture samples used to produce the anisotropically filtered texture mapped pixel.
