Texture units批量处理请求,执行寻址(选择mip级别, 和各项异性, 将uv转换为texel坐标,应用clamp/wrap模式,等等),就可以知道需要哪里的texel,之后在cache hierarchy中读取(如果L1 cache没有命中会通过Crossbar去找L2 Cache,如果也没有找到,就会去找DRAM) 如果许多挂起的纹理请求都想要相同的或附近的texels,那么在这里会...
When a cache miss occurs, the vertex texture cache unit continues to process subsequent vertex texture requests while data is being retrieved from memory for the cache miss. Because the vertex texture cache unit may output vertex texture map data in a different order than the corresponding vertex...
When the first kernel output (result) is the input of the second kernel, whether has a way to avoid the first kernel result transfer to global memory, that is to say, we transfer the first kernel result to some cache, and the second kernel uses directly, you know, the data transfer...
If the sparse tile is unmapped, the GPU loads zeroed data into the cache and returns it to your shader. Metal’s estimated texture access count is determined by the number of cache misses, and isn’t an exact count of the number of accesses to a specific region. If your app accesse...

Texture memory is also global memory, but with a cache. So if you read only once a texture element, on top of fetching it from global mem, you also have a cache miss that occurs. I am surprised it caused that much overhead.
The design is prationioned into two “paths”, a hit- and miss-path that either deal with misses inside the cache or outside the texture cache. The hit-path is naturally a shorter more latency optimised path. On the hit-path, the texture cache itself has been improved and is now 32KB...

(miss) rate to locate a specific memory block within the cache module, but also in an increase in the need to excessively swap memory blocks into and out of the cache module. To minimize this locality problem, texture mapping systems require accurate synchronization between the memory module ...
