Register (sociolinguistics)

FORM OF LANGUAGE USED FOR A PARTICULAR PURPOSE OR IN A PARTICULAR COMMUNICATIVE SITUATION

Levels of Register; Speech register; Diatype; Linguistic register; Language register; Formality scale; Lexicographical register; Formality level; Register (socio-linguistics); Speech levels; Formal register; Informal register; Low-register; High-register; Consultative register; Frozen register; Casual register; Intimate register

In sociolinguistics, a register is a variety of language used for a particular purpose or in a particular communicative situation. For example, when speaking officially or in a public setting, an English speaker may be more likely to follow prescriptive norms for formal usage than in a casual setting, for example, by pronouncing words ending in -ing with a velar nasal instead of an alveolar nasal (e.

Register (phonology)

FEATURE OF SOME TONAL LANGUAGES

Register language; Phonetic register; Pitch register

In phonology, a register, or pitch register, is a prosodic feature of syllables in certain languages in which tone, vowel phonation, glottalization or similar features depend upon one another.

Status register

REGISTER CONTAINING FLAGS GIVING ADDITIONAL INFORMATION CONCERNING A RESULT IN A PROCESSOR

Condition Code Register; Flag register; Condition code register; Processor flag

A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor. Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.

Wikipedia

In computer architecture, register renaming is a technique that abstracts logical registers from physical registers. Every logical register has a set of physical registers associated with it. When a machine language instruction refers to a particular logical register, the processor transposes this name to one specific physical register on the fly. The physical registers are opaque and cannot be referenced directly but only via the canonical names.

This technique is used to eliminate false data dependencies arising from the reuse of registers by successive instructions that do not have any real data dependencies between them. The elimination of these false data dependencies reveals more instruction-level parallelism in an instruction stream, which can be exploited by various and complementary techniques such as superscalar and out-of-order execution for better performance.
