Write-only memory — is the antithesis of read only memory (ROM). By definition, a WOM is a memory device which can be written but never read. Since there seems to be no obvious utility for such a memory circuit, from which data cannot be retrieved, the concept is… … Wikipedia
Read Only Memory — The notion of read only data can also refer to file system permissions. Read only memory (usually known by its acronym, ROM) is a class of storage media used in computers and other electronic devices. Because data stored in ROM cannot be modified … Wikipedia
Hazard (computer architecture) — Hazards are problems with the instruction pipeline in central processing unit (CPU) microarchitectures that potentially result in incorrect computation. There are typically three types of hazards: data hazards structural hazards control hazards… … Wikipedia
Register renaming — In computer engineering, register renaming refers to a technique usedto avoid unnecessary serialization of program operations imposed by the reuseof registers by those operations.Problem definitionPrograms are composed of instructions which… … Wikipedia
Data dependency — A data dependency in computer science is a situation in which a program statement (instruction) refers to the data of a preceding statement. In compiler theory, the technique used to discover data dependencies among statements (or instructions)… … Wikipedia
Instruction scheduling — In computer science, instruction scheduling is a compiler optimization used to improve instruction level parallelism, which improves performance on machines with instruction pipelines. Put more simply, without changing the meaning of the code, it … Wikipedia
Dependence analysis — In compiler theory, dependence analysis produces execution order constraints between statements/instructions. Broadly speaking, a statement S2 depends on S1 if S1 must be executed before S2. Broadly, there are two classes of dependencies control… … 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
Scoreboarding — is a centralized method, used in the CDC 6600, for dynamically scheduling a pipeline so that the instructions can execute out of order when there are no conflicts and the hardware is available. In a scoreboard, the data dependencies of every… … Wikipedia
Abhängigkeitsanalyse — Dependence analysis bzw. die Abhängigkeitsanalyse stellt im Compilerbau die Abhängigkeit zwischen Anweisungen fest. Daraus wird ermittelt wann es sicher ist die Ausführungsreihenfolge von Programmen zu verändern bzw. zu parallelisieren. Allgemein … Deutsch Wikipedia
