Linear address vs virtual address
Nettet虚拟内存(virtual memory) 这是对整个内存（不要与机器上插那条对上号）的抽像描述。 它是相对于物理内存来讲的，可以直接理解成“不直实的”，“假的”内存，例如，一个0x08000000内存地址，它并不对就物理地址上那个大数组中0x08000000 - 1那个地址元素； Nettet10. feb. 2024 · A relative address means a distance between two locations or addresses (which can be logical, linear/virtual or physical, which isn't important at this point).

Nettet15. mai 2015 · Lastly the mmu feature and virtual memory/virtual address space is that what appears in the virtual address space to be linear memory from address 0 to N does not have to be linear in physical memory. Mmus often work on one or various sized chunks, say for a simple case 4096 bytes per mmu entry. Nettet11. jan. 2024 · 2. A virtual address is not normal. It is used with paging. "Normal addresses" are direct physical addresses which access main memory directly. Intel's terminology says that virtual address will be translated by the segmentation unit to a linear address. The linear address will then be translated to physical address by the …
Nettet22. apr. 2024 · Solution 2. Logical Addressing : Address is formed by base and offset. This is nothing but segmented addressing, where the address (or offset) in the program is always used with the base value in the segment descriptor. Linear Addressing : Also called virtual address. Here adresses are contigous, but the physical address are not. NettetTypes of addresses in the x86 x64 family of Intel processors.Patreon: http://www.patreon.com/robotzer0
