Systems and methods for modifying the number of texture samples used to produce an anisotropically filtered texture mapped pixel may improve texture mapping performance. When the number of texture samples is reduced, fewer texels are read and fewer filtering computations are needed to produce a texture value for an anisotropic footprint. The number of texture samples is reduced based on the mip map level weight. The number of texture samples may also be modified using specific parameters for the coarse and / or fine mip map levels. The spacing between the texture samples along the major axis of anisotropy may be modified to improve image quality or texture cache performance.

The invention discloses a traffic mapping method for a time-sensitive network, comprising the following steps: a first device sends a request message to a network controller according to an IP address of a second device to obtain a TSN label; the first device writes the TSN label into the IP-MAC table; the first device communicates with the second device according to the IP address and TSN label of the second device. In this technical solution, when the first device accesses the peer communication device in the TSN network, it only needs to call the TSN label obtained from the network controller and stored in the IP-MAC table combined with the IP address of the peer device. Communication between the first device and the peer device. There is no need to add a TSN label to each communication data packet, which avoids the degradation of traffic mapping performance caused by this processing method. Therefore, the technical solution is simple and convenient, and can significantly improve network traffic mapping performance.
