Each context has its own virtual address space.
The segment register acts as an index into a table,which provides an offset to be added to the virtual address.
Granularity: The virtual address space is broken up into pages.
This allows up to 256 TB(248 bytes) of virtual address space.
Bit applications have a virtual address space limit of 4 GB under either kernel.
The address issued by a processor is called a virtual address.
The logical address is a virtual address and can be viewed by the user.
Typically, an operating system assigns each program its own virtual address space.
The CAM search key is the virtual address, and the search result is a physical address. .
Dynamic flow instruction cache memory organized around trace segments independent of virtual address line.
MIPS64 supports up to 64 bits of virtual address space and up to 59 bits of physical address space.
Both 32- and 64-bit applications,if not linked with"large address aware," are limited to 2 GB of virtual address space.
Systems with large virtual address ranges or amounts of real memory generally use larger page sizes.
The operating system maps different sections of the virtual address space with different size PTEs.
For instance, a 4 GiB virtual address space might be cut up into 1,048,576 pages of 4 KiB size, each of which can be independently mapped.
Virtually indexed, physically tagged(VIPT)caches use the virtual address for the index and the physical address in the tag.
If there is only one, different applications which are running at the same time share a single virtual address space, i.e.
Example: Assume that we have a TLB mapping of virtual address 0x2cfc7000 to physical address 0x12345000.
The operating system(OS) then handles the situation, perhaps by trying to find a spare frame of RAM andset up a new PTE to map it to the requested virtual address.
Another problem is homonyms,where the same virtual address maps to several different physical addresses. .
The virtual address is calculated with an adder, the relevant portion of the address extracted and used to index an SRAM, which returns the loaded data.
MIPS32 and MIPS32r2 support 32 bits of virtual address space and up to 36 bits of physical address space.
Sharing of virtual address space and inter-context communications can be provided by writing the same values in to the segment or page maps of different contexts.
Legacy mode allows for a maximum of 32 bit virtual addressing which limits the virtual address space to 4 GB.
This caching scheme can result in much faster lookups,since the MMU does not need to be consulted first to determine the physical address for a given virtual address.
Each cycle's instruction fetch has its virtual address translated through this TLB into a physical address. .
Larger virtual address space The AMD64 architecture defines a 64-bit virtual address format, of which the low-order 48 bits are used in current implementations.
In a Harvard architecture or modified Harvard architecture,a separate virtual address space or memory-access hardware may exist for instructions and data.
An associative cache of PTEs is called a translation lookaside buffer(TLB) andis used to avoid the necessity of accessing the main memory every time a virtual address is mapped.
If the CPU finds no valid entry for the virtual address in the page tables, it raises a page fault exception, which the operating system must handle.
