memory address space

(architecture)
1. Any part of a processor's address space that is occupied by memory.

2. The range of addresses seen by a memory device relative to the base address at which it is mapped into the processor's address space.

Client-server architectures offers greater protection against accidental data corruption than architectures where the database software shares the same memory address space as the applications that want to access the data, but at the cost of potential vulnerability against malicious attacks.
A stack pointer and 16-bit index registers enhance manipulation of tables, and the core's 16 Mbytes of linear memory address space streamlines paging operations above 64 Kbytes.
The AMD Opteron processor can deliver the computing power and the large memory address space that is needed to move to the next level in professional workstation applications.
Most servers today are either uniprocessor machines or machines that use symmetric multiprocessing (SMP) technology to create a single virtual processor from many processors that all share a single main memory address space.
In fact, every couple of years the amount of memory address space needed to run whatever software is mainstream at the time just about doubles.
Application developers using TeleUSE enjoy increased virtual memory address space and the performance benefits that 64-bit computing offers.
Adding 64-bit support provides larger memory address space and increased performance to support very large databases - something customers have been requesting for awhile in order to gain an even greater level of control of the environment to achieve a flexible and reliable way to deploy and manage applications online.
In addition, concerning 64-bit processing power, this support gives enterprise customers the benefit of increased computing power through substantially increasing the processing speed and memory address space capacity.
The DRC RPU contains specialized cells that can be used to accelerate numeric tasks which work on arrays stored in the memory address space of an AMD Opteron," commented Stephen Fried, Microway's president and CTO.
Unlike most clustered-computing schemes that rely on distributed memory (where the memory is specific to each processor), SGI's approach to global shared-memory eliminates data transfer overhead by providing a single memory address space (or single system image), allowing multiple processors and I/O nodes to access all the data in the system's memory directly and efficiently.
The Windows XP x64 operating system is the latest in technical computing - supporting 128 GB of RAM and 16 terabytes of virtual memory address space.
The Parameter Blocks are located at the top of the memory address space for the M58WR128ET, and at the bottom for the M58WR128EB.
