Cache only memory architecture — (COMA) is a computer memory organization for use in multiprocessors in which the local memories (typically DRAM) at each node are used as cache. This is in contrast to using the local memories as actual main memory, as in NUMA organizations. In… … Wikipedia
Memory architecture — describes the methods used to implement electronic computer data storage in a manner that is a combination of the fastest, most reliable, most durable, and least expensive way to store and retrieve information. Depending on the specific… … Wikipedia
Non-Uniform Memory Access — (NUMA) is a computer memory design used in Multiprocessing, where the memory access time depends on the memory location relative to a processor. Under NUMA, a processor can access its own local memory faster than non local memory, that is, memory … Wikipedia
Memory ordering — is a group of properties of the modern microprocessors, characterising their possibilities in memory operations reordering. It is a type of out of order execution. Memory reordering can be used to fully utilize different cache and memory banks.… … Wikipedia
Memory disambiguation — is a set of techniques employed by high performance out of order execution microprocessors that execute memory access instructions (loads and stores) out of program order. The mechanisms for performing memory disambiguation, implemented using… … Wikipedia
Memory coherence — is an issue that affects the design of computer systems in which two or more processors or cores share a common area of memory.[1][2][3][4] In a uniprocessor system (whereby, in today s terms, there exists only one core), there is only one… … Wikipedia
Memory protection — is a way to control memory access rights on a computer, and is a part of most modern operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug… … Wikipedia
Memory barrier — Memory barrier, also known as membar or memory fence or fence instruction, is a type of barrier and a class of instruction which causes a central processing unit (CPU) or compiler to enforce an ordering constraint on memory operations issued… … Wikipedia
Non-Uniform Memory Access — Non Uniform Memory Architecture oder kurz NUMA ist eine Computer Speicher Architektur für Multiprozessorsysteme, bei denen jeder Prozessor eigenen, lokalen Speicher hat, aber anderen Prozessoren über einen gemeinsamen Adressraum direkten Zugriff… … Deutsch Wikipedia
CPU cache — Cache memory redirects here. For the general use, see cache. A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the… … Wikipedia
Memory management unit — This 68451 MMU could be used with the Motorola 68010 A memory management unit (MMU), sometimes called paged memory management unit (PMMU), is a computer hardware component responsible for handling accesses to memory requested by the CPU. Its… … Wikipedia
