Processor register. A register-transfer level (RTL) description of a 8-bit register with detailed implementation, showing how 8 bits of data can be stored by using Flip-flops. A processor register is a quickly accessible location available to a computer's processor. [ 1] Registers usually consist of a small amount of fast storage, although some ...
Register allocation. In compiler optimization, register allocation is the process of assigning local automatic variables and expression results to a limited number of processor registers . Register allocation can happen over a basic block ( local register allocation ), over a whole function/ procedure ( global register allocation ), or across ...
Register window. In computer engineering, register windows are a feature which dedicates registers to a subroutine by dynamically aliasing a subset of internal registers to fixed, programmer-visible registers. Register windows are implemented to improve the performance of a processor by reducing the number of stack operations required for ...
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [ 1][ 2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level programming ...
Software license. Diagram of software under various licenses according to the FSF and their The Free Software Definition: on the left side "free software", on the right side "proprietary software". On both sides, and therefore mostly orthogonal, "free download" ( Freeware ). A software license is a legal instrument governing the use or ...
Register machine. In mathematical logic and theoretical computer science, a register machine is a generic class of abstract machines, analogous to a Turing machine and thus Turing complete. Unlike a Turing machine that uses a tape and head, a register machine utilizes multiple uniquely addressed registers to store non-negative integers.
Systems programming, or system programming, is the activity of programming [1] computer system software.The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user directly (e.g. word processor), whereas systems programming aims to produce software and ...
Computer reservation system. Computer reservation systems, or central reservation systems ( CRS ), are computerized systems used to store and retrieve information and conduct transactions related to air travel, hotels, car rental, or other activities. Originally designed and operated by airlines, CRSs were later extended for use by travel ...
