Bit addressability
WebIn a single-owner address space, the application owns the entire range of hardware addressability. For instance, if the hardware's maximum virtual address is 32 bits wide, applications generate 32-bit pointers. The implication is that the hardware supports a virtual machine environment in which every process “owns” the hardware's address space. WebApr 27, 2014 · The purpose for having byte addressability is because there are accesses to memory for things other than fetching instructions, and byte-level addressability is often useful for those scenarios. Note that there are architectures that are word addressable for things other than 8-bit bytes, but they aren't as common as 8-it addressable machines ...

Cheap Textbooks; WebSep 13, 2014 · It depends on how you address the data. If you use 32 bits to address each bit, you can address 2 32 bits or 4Gb = 512MB. If you address bytes like most current architectures it will give you 4GB.. But if you address much larger blocks you will need less bits to address 4GB. For example if you address each 512-byte block (2 9 bytes) you …
