在访问主存前，必须将虚拟存储器地址转换为实际存储器地址。
The virtual memory addresses must be translated into actual memory addresses before main memory is referenced.
上文中参照图5描述了物理地址与虚拟本地存储器地址之间的关系。
The relationship between the physical address and the virtual local memory address is described above in reference to Figure 5.
随后，处理逻辑通过查找虚拟本地存储器地址所表示的物理地址来处理存取请求(处理框602)。
Next, processing logic processes the access request by looking up the physical address represented by the virtual local memory address (processing block 602).
图7至图9描述虚拟地址空间中的图形本地存储器和系统存储器可能的分配的不同示例实施例。
Figures 7 through 9 describe different example embodiments of possible apportionments of graphics local memory and system memory in virtual address space.
参照图6，该方法通过处理逻辑接收对图形虚拟本地存储器地址空间中的位置的存储器存取请求开始(处理框600)。
Referring to Figure 6, the method begins by processing logic receiving a memory access request to a location in graphics virtual local memory address space (processing block 600).
参照图6，该方法通过处理逻辑接收对图形虚拟本地存储器地址空间中的位置的存储器存取请求开始(处理框600)。
