Flynn's taxonomyFlynn's taxonomy is a classification of computer architectures, proposed by Michael J. Flynn in 1966 and extended in 1972. The classification system has stuck, and it has been used as a tool in the design of modern processors and their functionalities. Since the rise of multiprocessingcentral processing units (CPUs), a multiprogramming context has evolved as an extension of the classification system.Scalar processorScalar processors are a class of computer processors that process only one data item at a time. Typical data items include integers and floating point numbers.
Single instruction, multiple dataSingle instruction, multiple data (SIMD) is a type of parallel computing (processing) in Flynn's taxonomy. SIMD describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA.

Instruction set architectureAn instruction set architecture (ISA) is an abstract model that defines the programmable interface of the CPU of a computer, defining how software interacts with hardware. A device (i.e. CPU) that interprets instructions described by an ISA is an implementation of that ISA. Generally, the same ISA is used for a family of related CPU devices.Array (data structure)In computer science, an array is a data structure consisting of a collection of elements (values or variables), of the same memory size, each identified by at least one array index or key, the collection of which may be a tuple, known as an index tuple. In general, an array is a mutable and linear collection of elements with the same data type.

ComputingComputing is any goal-oriented activity that requires, benefits from, or creates computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both hardware and software. Computing encompasses scientific, engineering, mathematical, technological, and social aspects.
Data compressionCompact encoding of digital dataIn information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information.SWARSIMD within a register (SWAR), also known by the name "packed SIMD" is a technique for performing parallel operations on data contained in a processor register. SIMD stands for single instruction, multiple data. Many modern general-purpose computer processors have some provisions for SIMD, in the form of a group of registers and instructions to make use of them.
Computer simulationComputer simulation is the running of a mathematical model on a computer, the model being designed to represent the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict.*As an Amazon Associate I earn from qualifying purchases.
