一、Mapping Functions 二、Persistently mapped memory(永久Mapping) 三、Cache flush and invalidate 四、检查内存是否可Mapping 总结 前言 本文为Vulkan® Memory Allocator系列系列教程,定时更新,请大家关注。如果需要深入学习Vulkan的同学,可以点击课程链接,学习链接:
In this technique, a number of mapping functions are used to transfer the data from main memory to cache memory. That means any main memory can be mapped into any cache line. Therefore, cache memory address is not in the use. Associative cache controller interprets the request by using the...
三、Cache flush and invalidate 在Vulkan当中,除非GPU上要使用,你是不需要对Mapped内存进行UnMap操作的。但是呢,如果这块内存不具备VK_MEMORY_PROPERTY_HOST_COHERENT_BIT这个能力的话,CPU与GPU的数据就无法及时更新入内存(存在缓存)。你就得在CPU端读取之前,调用invalidate cache操作;在CPU写入数据后,进行flush cache...

The bit-serial PEs must therefore communicate with the memories through serial-parallel converters that act as cache memories. 8. The next step involves logic design of the modules in the architecture— i.e., the PEs, memories, control units, etc. Control signals, which are also derived from...
WeakKeyDictionary and WeakValueDictionary use weak references in their implementation, setting up callback functions on the weak references that notify the weak dictionaries when a key or value has been reclaimed by garbage collection. WeakSet implements the set interface, but keeps weak references to...
This results in a lot of duplicate implementations of these mapping functions. The set of functions provided by different architectures also differs, with some having implementations of phys_to_virt & others not. A later patch will make use of phys_to_virt in architecture-neutral code, and so...
In addition, WAFTL maintains only part of the page-based mapping table in RAM. 7.3.3.2 CACH-FTL or Cache Aware Configurable Hybrid FTL CACH-FTL [BOU 13a] is another example of FTL that considers flash memory as a partitioned area, one region using a block-level mapping scheme and the ...
resulting in higher compression ratios and fewer artifacts. It also provides better performance because during the relief-mapping iterations, only the depth information is needed and a one-channel texture will be more cache friendly (the normal information will be needed only at the end ...
Allocates physical storage in memory or in the paging file on disk for all pages of a section. This is the default setting. SEC_IMAGE Not supported. SEC_NOCACHE Not supported. SEC_RESERVE Not supported. dwMaximumSizeHigh [in] Specifies the high-order 32 bits of the maximum size of the...
